AppSignal for Ruby gem Changelog

3.7.1

Published on 2024-04-29.

Changed

226a8f51 patch - If the gem can't find a valid log path in the app's log/ directory, it will no longer print the warning more than once.
5f97aa29 patch - Stop the minutely probes when Appsignal.stop is called. When Appsignal.stop is called, the probes thread will no longer continue running in the app process.
ccfa3572 patch - Listen to the APPSIGNAL_HTTP_PROXY environment variable in the extension installer. When APPSIGNAL_HTTP_PROXY is set during gem instal appsignal or bundle install, it will use the proxy specified in the APPSIGNAL_HTTP_PROXY environment variable to download the extension and agent.
123c7108 patch - Allow unregistering minutely probes. Use Appsignal::Probes.unregister to unregister probes registered with Appsignal::Probes.register if you do not need a certain probe, including default probes.
12305025 patch - Add Appsignal::Probes.register method as the preferred method to register probes. The Appsignal::Probes.probes.register and Appsignal::Minutely.probes.register methods are now deprecated.
12305025 patch - Automatically start new probes registered with Appsignal::Probes.register when the gem has already started the probes thread. Previously, the late registered probes would not be run.
12305025 patch - Rename the Minutely constant to Probes so that the API is the same between AppSignal integrations. If your apps calls Appsignal::Minutely, please update it to Appsignal::Probes. If your app calls Appsignal::Minutely after this upgrade without the name change, the gem will print a deprecation warning for each time the Appsignal::Minutely is called.
ee08eed2 patch - Log debug messages when metrics are received for easier debugging.

Fixed

a2f4b313 patch - Clear the AppSignal in memory logger, used during the gem start, after the file/STDOUT logger is started. This reduces memory usage of the AppSignal Ruby gem by a tiny bit, and prevent stale logs being logged whenever a process gets forked and starts AppSignal.

3.7.0

Published on 2024-04-22.

Added

5b0eb9b2 minor - Heartbeats are currently only available to beta testers. If you are interested in trying it out, send an email to support@appsignal.com!

Add heartbeats support. You can send heartbeats directly from your code, to track the execution of certain processes:
```
def send_invoices()
  # ... your code here ...
  Appsignal.heartbeat("send_invoices")
end
```
You can pass a block to Appsignal.heartbeat, to report to AppSignal both when the process starts, and when it finishes, allowing you to see the duration of the process:
```
def send_invoices()
  Appsignal.heartbeat("send_invoices") do
    # ... your code here ...
  end
end
```
If an exception is raised within the block, the finish event will not be reported to AppSignal, triggering a notification about the missing heartbeat. The exception will bubble outside of the heartbeat block.
5fc83cc1 patch - Implement the ignore_logs configuration option, which can also be configured as the APPSIGNAL_IGNORE_LOGS environment variable.

The value of ignore_logs is a list (comma-separated, when using the environment variable) of log line messages that should be ignored. For example, the value "start" will cause any message containing the word "start" to be ignored. Any log line message containing a value in ignore_logs will not be reported to AppSignal.

The values can use a small subset of regular expression syntax (specifically, ^, $ and .*) to narrow or expand the scope of lines that should be matched.

For example, the value "^start$" can be used to ignore any message that is exactly the word "start", but not messages that merely contain it, like "Process failed to start". The value "Task .* succeeded" can be used to ignore messages about task success regardless of the specific task name.

3.6.5

Published on 2024-04-17.

Fixed

83004ae5 patch - Check the redis-client gem version before installing instrumentation. This prevents errors from being raised on redis-client gem versions older than 0.14.0.

3.6.4

Published on 2024-03-25.

Fixed

09b9aa41 patch - Fix CPU user/system usage measurements, as to take into account the amount of CPUs available.

3.6.3

Published on 2024-03-20.

Added

e50433fb patch - Implement CPU count configuration option. Use it to override the auto-detected, cgroups-provided number of CPUs that is used to calculate CPU usage percentages.

To set it, use the the cpu_count configuration option or the APPSIGNAL_CPU_COUNT environment variable.

Fixed

c6dd9779 patch - Add request parameters, path and method tags to errors reported in controllers via the Rails error reporter.

3.6.2

Published on 2024-03-08.

Fixed

c3921865 patch - Revert Rack middleware changes (see changelog) to fix issues relating to Unicorn broken pipe errors and multiple requests merging into a single sample.

3.6.1

Published on 2024-03-05.

Added

8974d201 patch - Add activejob_report_errors config option. When set to "none", ActiveJob jobs will no longer report errors. This can be used in combination with custom exception reporting. By default, the config option has the value "all", which reports all errors.

3.6.0

Published on 2024-02-26.

Added

9984156f minor - Add instrumentation for all Rack responses, including streaming responses. New response_body_each.rack, response_body_call.rack and response_body_to_ary.rack events will be shown in the event timeline. This will show how long it takes to complete responses, depending on the response implementation.

This Sinatra route with a streaming response will be better instrumented, for example:
```
get "/stream" do
  stream do |out|
    sleep 1
    out << "1"
    sleep 1
    out << "2"
    sleep 1
    out << "3"
  end
end
```
e7706038 patch - Add histogram support to the OpenTelemetry HTTP server. This allows OpenTelemetry-based instrumentations to report histogram data to AppSignal as distribution metrics.

Changed

11220302 minor - Breaking change: Normalize CPU metrics for cgroups v1 systems. When we can detect how many CPUs are configured in the container's limits, we will normalize the CPU percentages to a maximum of 100%. This is a breaking change. Triggers for CPU percentages that are configured for a CPU percentage higher than 100% will no longer trigger after this update. Please configure triggers to a percentage with a maximum of 100% CPU percentage.
11220302 patch - Support fractional CPUs for cgroups v2 metrics. Previously a CPU count of 0.5 would be interpreted as 1 CPU. Now it will be correctly seen as half a CPU and calculate CPU percentages accordingly.
14aefc35 patch - Update bundled trusted root certificates.

Fixed

f2abbd6a patch - Fix (sub)traces not being reported in their entirety when the OpenTelemetry exporter sends one trace in multiple export requests. This would be an issue for long running traces, that are exported in several requests.

3.5.6

Changed

c76a3293 patch - Default headers don't contain REQUEST_URI anymore as query params are not filtered. Now REQUEST_PATH is sent instead to avoid any PII filtering.

3.5.5

Published on 2024-02-01.

Added

d44f7092 patch - Add support for the redis-client gem, which is used by the redis gem since version 5.

Changed

6b9b814d patch - Make the debug log message for OpenTelemetry spans from libraries we don't automatically recognize more clear. Mention the span id and the instrumentation library.
6b9b814d patch - Fix an issue where queries containing a MySQL leading type indicator would only be partially sanitised.

Fixed

e0f7b0e5 patch - Add more testing to JRuby extension installation to better report the installation result and any possible failures.

3.5.4

Changed

1a863490 patch - Fix disk usage returning a Vec with no entries on Alpine Linux when the df --local command fails.

Deprecated

bb98744b patch - Deprecate the Appsignal.set_host_gauge and Appsignal.set_process_gauge helper methods in the Ruby gem. These methods would already log deprecation warnings in the appsignal.log file, but now also as a Ruby warning. These methods will be removed in the next major version. These methods already did not report any metrics, and still do not.

Removed

1a863490 patch - Remove the appsignal_set_host_gauge and appsignal_set_process_gauge extension functions. These functions were already deprecated and did not report any metrics.

Fixed

0637b71d patch - Fix the Makefile log path inclusion in the diagnose report. The diagnose tool didn't look in the correct gem extension directory for this log file.
fe71d78b patch - Fix reporting of the Ruby syntax version and JRuby version in install report better.

3.5.3

Changed

50708677 patch - Log a warning when no mountpoints are found to report the disk usage metrics. This scenario shouldn't happen (it should log an error, message about skipping a mountpoint or log the disk usage). Log a warning to detect if this issue really occurs.

3.5.2

Fixed

a5963f65 patch - Fix Ruby Logger 1.6.0 compatibility

3.5.1

Fixed

2e93182b patch - Fix an error in the diagnose report when reading a file's contents results in an "Invalid seek" error. This could happen when the log path is configured to /dev/stdout, which is not supported.
ae0b779b patch - Fix logger compatibility with Ruby 3.3

3.5.0

Added

cee1676f minor - Nested errors are now supported. The error causes are stored as sample data on the transaction so they can be displayed in the UI.

3.4.16

Changed

2149c064 patch - Filter more disk mountpoints for disk usage and disk IO stats. This helps reduce noise in the host metrics by focussing on more important mountpoints.

The following mountpoint are ignored. Any mountpoint containing:
- /etc/hostname
- /etc/hosts
- /etc/resolv.conf
- /snap/
- /proc/

Fixed

2149c064 patch - - Support disk usage reporting (using df) on Alpine Linux. This host metric would report an error on Alpine Linux.
- When a disk mountpoint has no inodes usage percentage, skip the mountpoint, and report the inodes information successfully for the inodes that do have an inodes usage percentage.

3.4.15

Changed

3fe0fa7a patch - Bump agent to eec7f7b

Updated the probes dependency to 0.5.2. CPU usage is now normalized to the number of CPUs available to the container. This means that a container with 2 CPUs will have its CPU usage reported as 50% when using 1 CPU instead of 100%. This is a breaking change for anyone using the cpu probe.

If you have CPU triggers set up based on the old behaviour, you might need to update those to these new normalized values to get the same behaviour. Note that this is needed only if the AppSignal integration package you're using includes this change.

3.4.14

Changed

bd15ec20 patch - Bump agent to e8207c1.
- Add memory_in_percentages and swap_in_percentages host metrics that represents metrics in percentages.
- Ignore /snap/ disk mountpoints.
- Fix issue with the open span count in logs being logged as a negative number.
- Fix agent's TCP server getting stuck when two requests are made within the same fraction of a second.
09b45c80 patch - Bump agent to b604345.
- Add an exponential backoff to the retry sleep time to bind to the StatsD, NGINX and OpenTelemetry exporter ports. This gives the agent a longer time to connect to the ports if they become available within a 4 minute window.
- Changes to the agent logger:
  - Logs from the agent and extension now use a more consistent format in logs for spans and transactions.
  - Logs that are for more internal use are moved to the trace log level and logs that are useful for debugging most support issues are moved to the debug log level. It should not be necessary to use log level 'trace' as often anymore. The 'debug' log level should be enough.
- Add running_in_container to agent diagnose report, to be used primarily by the Python package as a way to detect if an app's host is a container or not.
1945d613 patch - Bump agent to 1dd2a18.
- When adding an SQL body attribute via the extension, instead of truncating the body first and sanitising it later, sanitise it first and truncate it later. This prevents an issue where queries containing very big values result in truncated sanitisations.

Fixed

c8698dca patch - Fix a deprecation warning for Sidekiq 7.1.6+ when an error is reported to AppSignal. (Thanks @bdewater-thatch!)
1c606c6a patch - Fix an internal error when some Redis info keys we're expecting are missing. This will fix the Sidekiq dashboard showing much less data than we can report when Redis is configured to not report all the data points we expect. You'll still miss out of metrics like used memory, but miss less data than before.

3.4.13

Added

29970d93 patch - Events from dry-monitor are now supported. There's also native support for rom-sql instrumentation events if they're configured.
27656744 patch - Support Rails 7.1 ActiveSupport Notifications handler.

Changed

6932bb3f patch - Add configuration load modifiers to diagnose report. Track if the APPSIGNAL_INACTIVE_ON_CONFIG_FILE_ERROR environment variable was set.

3.4.12

Added

441de353 patch - Add an option to not start AppSignal on config file errors. When the config/appsignal.yml file raises an error (due to ERB syntax issues or ERB errors), it will currently ignore the config file and try to make a configuration work from the other config sources (default, auto detection and system environment variables). This can cause unexpected behavior, because the config from the config file is not part of the loaded config.

In future versions of the Ruby gem, AppSignal will not start when the config file contains an error. To opt-in to this new behavior, set the APPSIGNAL_INACTIVE_ON_CONFIG_FILE_ERROR system environment variable to either 1 or true.

Changed

a42da92b patch - Log an error when sample data is of an invalid type. Accepted types are Array and Hash. If any other types are given, it will log an error to the appsignal.log file.

Fixed

8e636323 patch - Bump agent to 6133900.
- Fix disk_inode_usage metric name format to not be interpreted as a JSON object.

3.4.11

Added

4722292d patch - Re-add support for Ruby 2.7.
d782f9a6 patch - Add the host_role config option. This config option can be set per host to generate some metrics automatically per host and possibly do things like grouping in the future.

Changed

f61f4f68 patch - Bump agent to version d789895.
- Increase short data truncation from 2000 to 10000 characters.

3.4.10

Changed

61e093b8 patch - Bump agent to 6bec691.
- Upgrade sql_lexer to v0.9.5. It adds sanitization support for the THEN and ELSE logical operators.

3.4.9

Added

d048c778 patch - Allow passing custom data using the appsignal context via the Rails error reporter:

custom_data = { :hash => { :one => 1, :two => 2 }, :array => [1, 2] }
Rails.error.handle(:context => { :appsignal => { :custom_data => custom_data } }) do
  raise "Test"
end

3.4.8

Added

5ddde58b patch - Allow configuration of the agent's TCP and UDP servers using the bind_address config option. This is by default set to 127.0.0.1, which only makes it accessible from the same host. If you want it to be accessible from other machines, use 0.0.0.0 or a specific IP address.
74583d26 patch - Report total CPU usage host metric for VMs. This change adds another state tag value on the cpu metric called total_usage, which reports the VM's total CPU usage in percentages.

3.4.7

Added

46735abb patch - Use RENDER_GIT_COMMIT environment variable as revision if no revision is specified.

Changed

86856aae patch - Bump agent to 32590eb.
- Only ignore disk metrics that start with "loop", not all mounted disks that end with a number to report metrics for more disks.

3.4.6

Changed

85c155a0 patch - When sanitizing an array or hash, replace recursively nested values with a placeholder string. This fixes a SystemStackError issue when sanitising arrays and hashes.

3.4.5

Added

e5e79d9a patch - Add filter_metadata config option to filter metadata set on Transactions set by default. Metadata like path, (request) method, request_id, hostname, etc. This can be useful if there's PII or other sensitive data in any of the app's metadata.

Fixed

5a4797c8 patch - Fix Sinatra request custom request parameters method. If the Sinatra option params_method is set, a different method than params will be called on the request object to fetch the request parameters. This can be used to add custom filtering to parameters recorded by AppSignal.
9cdee8aa patch - Log error when the argument type of the breadcrumb metadata is invalid. This metadata argument should be a Hash, and other values are not supported. More information can be found in the Ruby gem breadcrumb documentation.
```
Appsignal.add_breadcrumb(
  "breadcrumb category",
  "breadcrumb action",
  "some message",
  { :metadata_key => "some value" } # This needs to be a Hash object
)
```

3.4.4

Fixed

17500724 patch - Fixed a bug that prevented log messages from getting to AppSignal when using the convenience methods as in:
```
Rails.logger.warn("Warning message")
```

3.4.3

Added

8e54a894 patch - Allow configuration of the agent's StatsD server port through the statsd_port option.

Changed

b9a8effe patch - Update bundled trusted root certificates.
d03735c7 patch - Bump agent to fd8ee9e.
- Rely on APPSIGNAL_RUNNING_IN_CONTAINER config option value before other environment factors to determine if the app is running in a container.
- Fix container detection for hosts running Docker itself.
- Add APPSIGNAL_STATSD_PORT config option.

3.4.2

Changed

645d749f patch - Update agent to version 6f29190.
- Log revision config in boot debug log.
- Update internal agent CLI start command.
- Rename internal _APPSIGNAL_ENVIRONMENT variable to _APPSIGNAL_APP_ENV to be consistent with the public version.

Fixed

4cd1601e patch - Do not run minutely probes on Rails console

3.4.1

Added

77ce4e39 patch - Add Rails error reporter support. Errors reported using Rails.error.handle are tracked as separate errors in AppSignal. We rely on our other Rails instrumentation to report the errors reported with Rails.error.record.

The error is reported under the same controller/job name, on a best effort basis. It may not be 100% accurate. If Rails.error.handle is called within a Rails controller or Active Job job, it will copy the AppSignal transaction namespace, action name and tags from the current transaction to the transaction for the Rails.error.handle reported error. If you call Appsignal.set_namespace, Appsignal.set_action or Appsignal.tag_request after Rails.error.handle, those changes will not be reflected up in the already reported error.

It is also possible to customize the AppSignal namespace and action name for the reported error using the appsignal context:
```
Rails.error.handle(:context => { :appsignal => { :namespace => "context", :action => "ContextAction" } }) do
  raise "Test"
end
```
All other key-values are reported as tags:
```
Rails.error.handle(:context => { :tag_key => "tag value" }) do
  raise "Test"
end
```
Integration with the Rails error reporter is enabled by default. Disable this feature by setting the enable_rails_error_reporter config option to false.
b4f58afd patch - Support Sidekiq in Rails error reporter. Track errors reported using Rails.error.handle in Sidekiq jobs, in the correct action. Previously it would report no action name for the incident, now it will use the worker name by default.

Changed

e0332791 patch - Set the AppSignal transaction namespace, action name and some tags, before Active Job jobs are performed. This allows us to check what the namespace, action name and some tags are during the instrumentation itself.
4a40699a patch - The AppSignal gem requires Ruby 3 or higher to run. Remove unnecessary Ruby version checks that query Ruby 2.7 or lower.
da7d1c76 patch - Internal refactor of Ruby code due to RuboCop upgrade. Use the public prepend method to prepend AppSignal instrumentation modules.

Fixed

009d533f patch - Fix a bug when using ActiveSupport::TaggedLogging calling the silence method.

3.4.0

Deprecated

6f9b7a4d minor - Remove support for Ruby versions in that are end of life, following our maintenance policy. Please upgrade your Ruby version to a supported version before upgrading AppSignal.

Fixed

5b7735ac patch - Fix Logger add method signature error

3.3.10

Fixed

48389475 patch - The Appsignal::Logger is now compatible with ActiveSupport::Logger.broadcast.

3.3.9

Fixed

a6db61b9 patch - Fixed an error when using our Logging feature with Ruby's default logger formatter.

3.3.8

Added

2fc6ba85 patch - Support "warning" value for log_level config option. This option was documented, but wasn't accepted and fell back on the "info" log level if used. Now it works to configure it to the "warn"/"warning" log level.
c04f7783 patch - Add global VM lock metrics. If the gvltools library is installed, AppSignal for Ruby will report metrics on the global VM lock and the number of waiting threads in your application.

3.3.7

Added

a815b298 patch - Support cgroups v2. Used by newer Docker engines to report host metrics. Upgrade if you receive no host metrics for Docker containers.

Changed

8e67159e patch - Configure AppSignal with the RACK_ENV or RAILS_ENV environment variable in diagnose CLI, if present. Makes it easier to run the diagnose CLI in production, without having to always specify the environment with the --environment CLI option.
a815b298 patch - Allow transaction events to have a duration up to 48 hours before being discarded.

Fixed

a815b298 patch - Remove trailing comments in SQL queries, ensuring queries are grouped consistently.
a815b298 patch - Fix an issue where events longer than forty-eight minutes would be shown as having a zero-second duration.

3.3.6

Changed

962d069c patch - Bump agent to 8d042e2.
- Support multiple log formats.

3.3.5

Changed

fc85adde patch - Bump agent to 0d593d5.
- Report shared memory metric state.

3.3.4

Added

75e29895 patch - Add NGINX metrics support. See our documentation for details.

3.3.3

Fixed

b2f872bc patch - Fix the T_DATA warning originating from the AppSignal C extension on Ruby 3.2.

3.3.2

Changed

d1b960f0 patch - Reduce our dependency on YAML during installation. Instead of a YAML file with details about the extension download location, use a pure Ruby file. This is a partial fix for the installation issue involving psych version 5.

Fixed

e1e598ae patch - Skip the .gemrc config during installation if it raises an error loading it. This can be caused when the psych gem version 5 is installed on Ruby < 3.2. Use the HTTP_PROXY environment variable instead to configure the HTTP proxy that should be used during installation.

3.3.1

Added

7f62ada8 patch - Track the Operating System release/distro in the diagnose report. This helps us with debugging what exact version of Linux an app is running on, for example.

Fixed

1443e05f patch - Attempt to load C extension from lib/ directory. Fixes an issue where JRuby would fail to load the extension from the ext/ directory, as the directory is cleaned after installation when using RubyGems 3.4.0.

3.3.0

Added

e4314b5b minor - Hanami 2 is now supported. Requests will now appear as performance measurements.

3.2.2

Changed

2b1964d9 patch - Track new Ruby 3.2 VM cache metrics. In Ruby 3.2 the class_serial and global_constant_state metrics are no longer reported for the "Ruby (VM) metrics" magic dashboard, because Ruby 3.2 removed these metrics. Instead we will now report the new constant_cache_invalidations and constant_cache_misses metrics reported by Ruby 3.2.
6804e898 patch - Use log formatter if set in logger

3.2.1

Fixed

5e87aa34 patch - Support the http.rb gem's URI argument using objects with the #to_s method. A Ruby URI object is no longer required.

3.2.0

Added

199d05c0 minor - Support the http.rb gem. Any outgoing requests will be tracked as events on the incident event timeline. This instrumentation is activated automatically, but can be disable by setting the instrumentation_http_rb option to false.
9bcd107d minor - Support log collection from Ruby apps using the new AppSignal Logging feature. Learn more about AppSignal's Logging on our docs.

3.1.6

Fixed

a03b7246 patch - Support Sidekiq 7 in the Sidekiq minutely probe. It will now report metrics to Sidekiq magic dashboard for Sidekiq version 7 and newer.

3.1.5

Changed

4035c3c2 patch - Bump agent to version 813a59b
- Fix http proxy config option parsing for port 80.
- Fix the return value for appsignal_import_opentelemetry_span extension function in appsignal.h.

Fixed

feb60fb8 patch - Fix NoMethodError for AppSignal Puma plugin for Puma 6. Puma 5 is also still supported.

3.1.4

Added

ffe49cfe patch - Support temporarily disabling GC profiling without reporting inaccurate gc_time metric durations. The MRI probe's gc_time will not report any value when the GC::Profiler.enabled? returns false.

Changed

af7e666c patch - Listen if the Ruby Garbage Collection profiler is enabled and collect how long the GC is running for the Ruby VM magic dashboard. An app will need to call GC::Profiler.enable to enable the GC profiler. Do not enable this in production environments, or at least not for long, because this can negatively impact performance of apps.

Fixed

b3a163be patch - Fix the MRI probe using the Garbage Collection profiler instead of the NilProfiler when garbage collection instrumentation is not enabled for MRI probe. This caused unnecessary overhead.

3.1.3

Added

811a1082 patch - Add the Transaction.current? helper to determine if any Transaction is currently active or not. AppSignal NilTransactions are not considered active transactions.

Changed

dc50d889 patch - Rename the (so far privately reported) gc_total_time metric to gc_time. It no longer reports the total time of Garbage Collection measured, but only the time between two (minutely) measurements.

Fixed

7cfed987 patch - Fix error on unknown HTTP request method. When a request is made with an unknown request method, triggering and ActionController::UnknownHttpMethod, it will no longer break the AppSignal instrumentation but omit the request method in the sample data.

3.1.2

Changed

1b95bb4c patch - Report Garbage Collection total time metric as the delta between measurements. This reports a more user friendly metric that doesn't always goes up until the app restarts or gets a new deploy. This metric is reported 0 by default without GC::Profiler.enable having been called.
61a78fb0 patch - Bump agent to 06391fb
- Accept "warning" value for the log_level config option.
- Add aarch64 Linux musl build.
- Improve debug logging from the extension.
- Fix high CPU issue for appsignal-agent when nothing could be read from the socket.

3.1.1

Changed

e225c798 patch - Report all Ruby VM metrics as gauges. We previously reported some metrics as distributions, but all fields for those distributions would report the same values.

Fixed

31fd19c6 patch - Add hostname tag for Ruby VM metrics. This allows us to graph every host separately and multiple hosts won't overwrite each other metrics.

3.1.0

Added

d10c3f32 minor - Add tracking of thread counts, garbage collection runs, heap slots and other garbage collection stats to the default MRI probe. These metrics will be shown in AppSignal.com in a new Ruby VM Magic Dashboard.

Changed

114fe4f9 patch - Bump agent to v-d573c9b
- Display unsupported OpenTelemetry spans in limited form.
- Clean up payload storage before sending. Should fix issues with locally queued payloads blocking data from being sent.
- Add appsignal_create_opentelemetry_span function to create spans for further modification, rather than only import them.
dd803449 patch - Report gauge delta value for allocated objects. This reports a more user friendly metric we can graph with a more stable continuous value in apps with stable memory allocation.
547f925e patch - Report gauge delta value for Garbage Collection counts. This reports a more user friendly metric that doesn't always goes up until the app restarts or gets a new deploy.

Fixed

e555a81a patch - Fix FFI function calls missing arguments for appsignal_free_transaction and appsignal_free_data extension functions. This fixes a high CPU issue when these function calls would be retried indefinitely.

3.0.27

Fixed

7032dc4b patch - Use Dir.pwd to determine the current directory in the Capistrano 3 integration. It previously relied on ENV["pwd"] which returned nil in some scenarios.

3.0.26

Removed

56ec42ae patch - Remove Moped support as it is no longer the official Ruby Mongo driver and it's been unmaintained for 7 years.

Fixed

991ca18d patch - Fix runtime errors on YAML load with older psych versions (< 4) used in combination with newer Ruby version (3.x).

3.0.25

Added

399cf790 patch - Sanitize ActiveRecord::RecordNotUnique error messages to not include any database values that is not unique in the database. This ensures no personal information is sent to AppSignal through error messages from this error.

3.0.24

Changed

964861f7 patch - Bump agent to v-f57e6cb
- Enable process metrics on Heroku and Dokku

3.0.23

Fixed

d73905d3 patch - Fix sanitized values wrapped in Arrays. When a value like [{ "foo" => "bar" }] was sanitized it would be stored as { "foo" => "?" }, omitting the parent value's Array square brackets. Now values will appear with the same structure as they were originally sanitized. This only applies to certain integrations like MongoDB, moped and ElasticSearch.
096d3cdf patch - Fix the ActiveJob default_queue_name config option issue being reset to "default". When ActiveJob default_queue_name was set in a Rails initializer it would reset on load to default. Now the default_queue_name can be set in an initializer as well.

3.0.22

Changed

9762e79d patch - Bump agent to v-bbc830a
- Support batched statsd messages
- Set start times for spans with traceparents
- Check duration in transactions for negative and too high value

3.0.21

Changed

548dd6f4 patch - Add config override source. Track final decisions made by the Ruby gem in the configuration in the override config source. This will help us track new config options which are being set by their deprecated predecessors in the diagnose report.

Removed

3f503ade patch - Remove internal Appsignal.extensions system. It was unused.

3.0.21.alpha.1

Changed

f19d9dcc patch - The MongoDB query sanitization now shows all the attributes in the query at all levels. Only the actual values are filtered with a ? character. Less MongoDB queries are now marked as N+1 queries when they weren't the exact same query. This increases the number of unique events AppSignal tracks for MongoDB queries.

3.0.20

Added

35bd83b8 patch - Add send_session_data option to configure if session data is automatically included transactions. By default this is turned on. It can be disabled by configuring send_session_data to false.

Deprecated

35bd83b8 patch - Deprecate skip_session_data option in favor of the newly introduced send_session_data option. If it is configured it will print a warning on AppSignal load, but will also retain its functionality until the config option is fully removed in the next major release.
e51a8fb6 patch - Warn about the deprecated working_dir_path option from all config sources. It previously only printed a warning when it was configured in the config/appsignal.yml file, but now also prints the warning if it's set via the Config class initialize options and environment variables. Please use the working_directory_path option instead.

Fixed

c9000eee patch - Fix reported Ruby version in diagnose report. It would report only the first major release of the series, e.g. 2.6.0 for 2.6.1.

3.0.19

Changed

2587eae3 patch - Store the extension install report as JSON, instead of YAML. Reduces internal complexity.

Fixed

243c1ed4 patch - Improve compatibility with the sequel-rails gem by tracking the performed SQL query in instrumentation events.

3.0.18

Added

d7bfcdf1 patch - Add Ruby 3.1.0 support. There was an issue with YAML.load arguments when parsing the appsignal.yml config file.

3.0.17

Fixed

f9d57752 patch - Use the log_level option for the Ruby gem logger. Previously it only configured the extension and agent loggers. Also fixes the debug and transaction_debug_mode option if no log_level is configured by the app.

3.0.16

Added

fe226e99 patch - Add experimental Span API. This is not loaded by default and we do not recommend using it yet.
84b1ba18 patch - Add "log_level" config option. This new option allows you to define the kind of messages AppSignal's will log and up. The "debug" option will log all "debug", "info", "warning" and "error" log messages. The default value is: "info"

The allowed values are:
- error
- warning
- info
- debug
6b2ecca2 patch - Clean up index values in error messages from PG index violation errors.

Changed

25bde454 patch - Order the config options alphabetically in diagnose report output.
fe226e99 patch - Use the filter_parameters and filter_session_data options to filter out specific parameter keys or session data keys for the experimental Span API. Previously only the (undocumented) filter_data_keys config option was available to filter out all kinds of app data.
fe226e99 patch - Standardize diagnose validation failure message. Explain the diagnose request failed and why.
fe226e99 patch - Bump agent to v-5b63505
- Only filter parameters with the filter_parameters config option.
- Only filter session data with the filter_session_data config option.
3ad95ea5 patch - Bump agent to v-0db01c2
- Add log_level config option in extension.
- Deprecate debug and transaction_debug_mode option in extension.

Deprecated

84b1ba18 patch - Deprecate "debug" and "transaction_debug_mode" config options in favor of the new "log_level" config option.

3.0.15

b40b3b4f patch - Print String values in the diagnose report surrounded by quotes. Makes it more clear that it's a String value and not a label we print.
fd6faf16 patch - Bump agent to 09308fb
- Update sql_lexer dependency with support for reversed operators in queries.
- Add debug level logging to custom metrics in transaction_debug_mode.
- Add hostname config option to standalone agent.

3.0.14

c40f6d75 patch - Add minutely probe that collects metrics for :class_serial and :global_constant_state from RubyVM.
7c18fb6d patch - Bump agent to 7376537
- Support JSON PostgreSQL operator in sql_lexer.
- Do not strip comments from SQL queries.
8d7b80ea patch - Add configuration option for the AppSignal agent StatsD server. This is on by default, but you can disable it with enable_statsd: false.

3.0.13

5c202185 patch - Bump agent to v-0318770.
- Improve Dokku platform detection. Do not disable host metrics on Dokku.
- Report CPU steal metric.

88f7d585 patch - Bump agent to c2024bf with appsignal-agent diagnose timing issue fix when reading the report and improved filtering for HTTP request transmission logs.

3.0.9

44dd4bdc patch - Check Rails.backtrace_cleaner method before calling the method. This prevents a NoMethodError from being raised in some edge cases.

3.0.8

5f94712d patch - Add the APPSIGNAL_BUILD_FOR_LINUX_ARM flag to allow users to enable the experimental Linux ARM build for 64-bit hosts. Usage: export APPSIGNAL_BUILD_FOR_LINUX_ARM=1 bundle install. Please be aware this is an experimental build. Please report any issue you may encounter at our support email.

3.0.7

27f9b178 patch - Bump agent to 6caf6d0. Replaces curl HTTP client and includes various other maintenance updates.
665d883a patch - Improve Puma plugin stats collection. Instead of starting the AppSignal gem in the main process we send the stats to the AppSignal agent directly using StatsD. This should improve compatibility with phased restarts. If you use prune_bundler, you will need to add AppSignal to the extra extra_runtime_dependencies list.
```
# config/puma.rb
plugin :appsignal
extra_runtime_dependencies ["appsignal"]
```

3.0.6

d354d79b patch - Add Excon integration. Track requests and responses from the Excon gem.
4c32e818 patch - Support Redis eval statements better by showing the actual script that was performed. Instead of showing eval ? ? ? (for a script with 2 arguments), show <script> ? ?, where <script> is whatever script was sent to Redis.new.eval("<script>").

3.0.5

4bddac36 patch - Skip empty HTTP proxy config. When any of the HTTP proxy config returns an empty string, skip this config. This fixes installation issues where an empty String is used as a HTTP proxy, causing a RuntimeError upon installation.

3.0.4

6338e822 patch - Drop logger level to debug. Reduce the output on the "info" level and only show these messages in debug mode. This should reduce the noise for users running AppSignal with the STDOUT logger, such as is the default on Heroku.
