# New Relic Ruby Agent Release Notes #
## v3.6.7 ##
* Resque-pool support
Resque processes started via the resque-pool gem weren't recognized by the
Ruby agent. The agent now starts correctly in those worker processes.
* Environment-based configuration
All settings in newrelic.yml can now be configured via environment variables.
See https://newrelic.com/docs/ruby/ruby-agent-configuration for full details.
* Additional locking option for Resque (3.6.7.159)
There have been reports of worker process deadlocks in Resque when using the
Ruby agent. An optional lock is now available to avoid those deadlocks. See
https://newrelic.com/docs/ruby/resque-instrumentation for more details.
* HTTP connection setup timeout (3.6.7.159)
HTTP initialization in the agent lacked an appropriate timeout,
leading to dropouts in reporting under certain network error conditions.
* Unnecessary requests from Resque jobs (3.6.7.159)
An issue causing Resque jobs to unnecessarily make requests against New Relic
servers was fixed.
* Fix compatibility issues with excon and curb instrumentation
This release of the agent fixes a warning seen under certain circumstances
with the excon gem (most notably, when excon was used by fog), as well as
a bug with the curb instrumentation that conflicted with the feedzirra gem.
* Allow license key to be set by Capistrano variables
A license key can be passed via a Capistrano variable where previously it
could only be in newrelic.yml. Thanks Chris Marshall for the contribution!
* Make HTTP client instrumentation aware of "Host" request header
If a "Host" header is set explicitly on an HTTP request, that hostname will
be used for external metrics. Thanks Mislav Marohnić for the contribution!
* Fix ActiveSupport::Concern warnings with MethodTracer
Including NewRelic::Agent::MethodTracer in a class using Concerns could cause
deprecation warnings. Thanks Mike Połtyn for the contribution!
* Fix Authlogic constant name
Code checking for the Authlogic module was using in the wrong case. Thanks
Dharam Gollapudi for the contribution!
## v3.6.6 ##
* HTTPClient and Curb support
The Ruby agent now supports the HTTPClient and Curb HTTP libraries! Cross
application tracing and more is fully supported for these libraries. For more
details see https://newrelic.com/docs/ruby/ruby-http-clients.
* Sinatra startup improvements
In earlier agent versions, newrelic_rpm had to be required after Sinatra to
get instrumentation. Now the agent should start when your Sinatra app starts
up in rackup, thin, unicorn, or similar web servers.
* Puma clustered mode support
Clustered mode in Puma was not reporting data without manually adding a hook
to Puma's configuration. The agent will now automatically add this hook.
* SSL certificate verification
Early versions of the agent's SSL support provided an option to skip
certificate verification. This option has been removed.
## v3.6.5 ##
* Rails 4.0 Support
The Ruby agent is all set for the recent general release of Rails 4.0! We've
been tracking the RC's, and that work paid off. Versions 3.6.5 and 3.6.4 of
the Ruby agent should work fine with Rails 4.0.0.
* Excon and Typhoeus support
The Ruby agent now supports the Excon and Typhoeus HTTP libraries! For more
details see https://newrelic.com/docs/ruby/ruby-http-clients.
## v3.6.4 ##
* Exception Whitelist
We've improved exception message handling for applications running in
high security mode. Enabling 'high_security' now removes exception messages
entirely rather than simply obfuscating any SQL.
By default this feature affects all exceptions, though you can configure a
whitelist of exceptions whose messages should be left intact.
More details: https://newrelic.com/docs/ruby/ruby-agent-configuration
* Fix a race condition affecting some Rails applications at startup
Some Rails applications using newrelic_rpm were affected by a race condition
at startup that manifested as an error when model classes with associations
were first loaded. The cause of these errors has been addressed by moving the
generation of the agent's EnvironmentReport on startup from a background
thread to the main thread.
## v3.6.3 ##
* Better Sinatra Support
A number of improvements have been made to our Sinatra instrumentation.
More details: https://newrelic.com/docs/ruby/sinatra-support-in-the-ruby-agent
Sinatra instrumentation has been updated to more accurately reflect the final
route that was actually executed, taking pass and conditions into account.
New Relic middlewares for error collection, real user monitoring, and cross
application tracing are automatically inserted into the middleware stack.
Ignoring routes, similar to functionality available to Rails controllers, is
now available in Sinatra as well.
Routes in 1.4 are properly formatting in transaction names. Thanks Zachary
Anker for the contribution!
* Padrino Support
Along with improving our support of Sinatra, we've also extended that to
supporting Padrino, a framework that builds on Sinatra. Web transactions
should show up in New Relic now for Padrino apps automatically. The agent has
been tested against the latest Padrino in versions 0.11.x and 0.10.x.
* Main overview graph only shows web transactions
In the past database times from background jobs mixed with other web transaction
metrics in the main overview graph. This often skewed graphs. A common workaround
was to send background jobs to a separate application, but that should no longer
be necessary as the overview graphs now only represent web transactions.
## v3.6.2 ##
* Sequel support
The Ruby agent now supports Sequel, a database toolkit for Ruby. This
includes capturing SQL calls and model operations in transaction traces, and
recording slow SQL calls. See https://newrelic.com/docs/ruby/sequel-instrumentation
for full details.
* Thread profiling fix
The prior release of the agent (version 3.6.1) broke thread profiling. A
profile would appear to run, but return no data. This has been fixed.
* Fix for over-counted Net::HTTP calls
Under some circumstances, calls into Net::HTTP were being counted twice in
metrics and transaction traces. This has been fixed.
* Missing traced errors for Resque applications
Traced errors weren't displaying for some Resque workers, although the errors
were factored into the overall count graphs. This has been fixed, and traced
errors should be available again after upgrading the agent.
## v3.6.1 ##
* Full URIs for HTTP requests are recorded in transaction traces
When recording a transaction trace node for an outgoing HTTP call via
Net::HTTP, the agent will now save the full URI (instead of just the hostname)
for the request. Embedded credentials, the query string, and the fragment will
be stripped from the URI before it is saved.
* Simplify Agent Autostart Logic
Previously the agent would only start when it detected a supported
"Dispatcher", meaning a known web server or background task framework. This
was problematic for customers using webservers that the agent was not
configured to detect (e.g. Puma). Now the agent will attempt to report any
time it detects it is running in a monitored environment (e.g. production).
There are two exceptions to this. The agent will not autostart in a rails
console or irb session or when the process was invoked by a rake task (e.g.
rake assets:precompile). The NEWRELIC_ENABLE environment variable can be set
to true or false to force the agent to start or not start.
* Don't attempt to resolve collector hostname when proxy is in use
When a proxy is configured, the agent will not attempt to lookup and cache the
IP address of New Relic server to which it is sending data, since DNS may not
be available in some environments. Thanks to Bill Kirtley for the contribution
* Added NewRelic::Agent.set_transaction_name and NewRelic::Agent.get_transaction_name
Ordinarily the name of your transaction is defined up-front, but if you'd like to
change the name of a transaction while it is still running you can use
**NewRelic::Agent.set_transaction_name()**. Similarly, if you need to know the name
of the currently running transaction, you can use **NewRelic::Agent.get_transaction_name()**.
## v3.6.0 ##
* Sidekiq support
The Ruby agent now supports the Sidekiq background job framework. Traces from
Sidekiq jobs will automatically show up in the Background tasks on New Relic
similar to Resque and Delayed::Job tasks.
* Improved thread safety
The primary metrics data structures in the Ruby agent are now thread safe.
This should provide better reliability for the agent under JRuby and threaded
scenarios such as Sidekiq or Puma.
* More robust environment report
The agent's analysis of the local environment (e.g. OS, Processors, loaded
gems) will now work in a wider variety of app environments, including
Sinatra.
* Experimental Rainbows! support
The Ruby agent now automatically detects and instruments the Rainbows! web
server. This support is considered experimental at present, and has not been
tested with all dispatch modes.
Thanks to Joseph Chen for the contribution.
* Fix a potential file descriptor leak in Resque instrumentation
A file descriptor leak that occurred when DontPerform exceptions were used to
abort processing of a job has been fixed. This should allow the Resque
instrumentation work correctly with the resque-lonely_job gem.
## v3.5.8 ##
* Key Transactions
The Ruby agent now supports Key Transactions! Check out more details on the
feature at https://newrelic.com/docs/site/key-transactions
* Ruby 2.0
The Ruby agent is compatible with Ruby 2.0.0 which was just released.
* Improved Sinatra instrumentation
Several cases around the use of conditions and pass in Sinatra are now
better supported by the Ruby agent. Thanks Konstantin for the help!
* Outbound HTTP headers
Adds a 'X-NewRelic-ID' header to outbound Net::HTTP requests. This change
helps improve the correlation of performance between services in a service-
oriented architecture for a forthcoming feature. In the meantime, to disable
the header, set this in your newrelic.yml:
cross_application_tracer:
enabled: false
* Automatically detect Resque dispatcher
The agent does better auto-detection for the Resque worker process.
This should reduce the need to set NEW_RELIC_DISPATCHER=resque directly.
## v3.5.7 ##
* Resolved some issues with tracking of frontend queue time, particularly
when the agent is running on an app hosted on Heroku. The agent will now
more reliably parse the headers described in
https://newrelic.com/docs/features/tracking-front-end-time and will
automatically detect whether the times provided are in seconds,
milliseconds or microseconds.
## v3.5.6 ##
* Use HTTPS by default
The agent now defaults to using SSL when it communicates with New Relic's
servers. By default is already configured New Relic does not transmit any
sensitive information (e.g. SQL parameters are masked), but SSL adds an
additional layer of security. Upgrading customers may need to remove the
"ssl: false" directive from their newrelic.yml to enable ssl. Customers on
Jruby may need to install the jruby-openssl gem to take advantage of this
feature.
* Fix two Resque-related issues
Fixes a possible hang on exit of an instrumented Resque master process
(https://github.com/defunkt/resque/issues/578), as well as a file descriptor
leak that could occur during startup of the Resque master process.
* Fix for error graph over 100%
Some errors were double counted toward the overall error total. This
resulted in graphs with error percentages over 100%. This duplication did
not impact the specific error traces captured, only the total metric.
* Notice gracefully handled errors in Sinatra
When show_exceptions was set to false in Sinatra, errors weren't caught
by New Relic's error collector. Now handled errors also have the chance
to get reported back.
* Ruby 2.0 compatibility fixes
Ruby 2.0 no longer finds protected methods by default, but will with a flag.
http://tenderlovemaking.com/2012/09/07/protected-methods-and-ruby-2-0.html
Thanks Ravil Bayramgalin and Charlie Somerville for the fixes.
* Auto-detect Trinidad as dispatcher
Code already existing for detecting Trinidad as a dispatcher, but was only
accessible via an ENV variable. This now auto-detects on startup. Thanks
Robert Rasmussen for catching that.
* Coercion of types in collector communication
Certain metrics can be recorded with a Ruby Rational type, which JSON
serializes as a string rather than a floating point value. We now treat
coerce each outgoing value, and log issues before sending the data.
* Developer mode fix for chart error
Added require to fix a NameError in developer mode for summary page. Thanks
to Ryan B. Harvey.
* Don't touch deprecated RAILS_ROOT if on Rails 3
Under some odd startup conditions, we would look for the RAILS_ROOT constant
after failing to find the ::Rails.root in a Rails 3 app, causing deprecation
warnings. Thanks for Adrian Irving-Beer for the fix.
## v3.5.5 ##
* Add thread profiling support
Thread profiling performs statistical sampling of backtraces of all threads
within your Ruby processes. This feature requires MRI >= 1.9.2, and is
controlled via the New Relic web UI. JRuby support (in 1.9.x compat mode) is
considered experimental, due to issues with JRuby's Thread#backtrace.
* Add audit logging capability
The agent can now log all of the data it sends to the New Relic servers to
a special log file for human inspection. This feature is off by default, and
can be enabled by setting the audit_log.enabled configuration key to true.
You may also control the location of the audit log with the audit_log.path key.
* Use config system for dispatcher, framework, and config file detection
Several aspects of the agent's configuration were not being handled by the
configuration system. Detection/configuration of the dispatcher (e.g. passenger,
unicorn, resque), framework (e.g. rails3, sinatra), and newrelic.yml
location are now handled via the Agent environment, manual, and default
configuration sources.
* Updates to logging across the agent
We've carefully reviewed the logging messages that the agent outputs, adding
details in some cases, and removing unnecessary clutter. We've also altered
the startup sequence to ensure that we don't spam STDOUT with messages
during initialization.
* Fix passing environment to manual_start()
Thanks to Justin Hannus. The :env key, when passed to Agent.manual_start,
can again be used to specify which section of newrelic.yml is loaded.
* Rails 4 support
This release includes preliminary support for Rails 4 as of 4.0.0.beta.
Rails 4 is still in development, but the agent should work as expected for
people who are experimenting with the beta.
## v3.5.4 ##
* Add queue time support for sinatra apps
Sinatra applications can now take advantage of front end queue time
reporting. Thanks to Winfield Peterson for this contribution.
* Simplify queue time configuration for nginx 1.2.6+
Beginning in version 1.2.6, recently released as a development version, the
$msec variable can be used to set an http header. This change allows front
end queue time to be tracked in New Relic simply by adding this line to the
nginx config:
proxy_set_header X-Queue-Start "t=${msec}000"
It will no longer be necessary to compile a patched version of nginx or
compile in the perl or lua module to enable this functionality.
Thanks to Lawrence Pit for the contribution.
* Report back build number and stage along with version info
In the 3.5.3 series the agent would fail to report its full version number
to NewRelic's environment report. For example it would report its version
as 3.5.3 instead of 3.5.3.25 or 3.5.3.25.beta. The agent will now report
its complete version number as defined in newrelic_rpm.gemspec.
* The host and the port that the agent reports to can now be set from environment vars
The host can be set with NEW_RELIC_HOST and the port with NEW_RELIC_PORT. These setting
will override any other settings in your newrelic.yml.
* Fix RUM reporting to multiple applications
When the agent is configured to report to multiple "roll up" applications
RUM did not work correctly.
## v3.5.3 ##
* Update the collector protocol to use JSON and Ruby primitives
The communication between the agent and the NewRelic will not longer be
marshaled Ruby objects, but rather JSON in the case of Ruby 1.9 and marshaled
Ruby primitives in the case of 1.8. This results in greater harvest efficiency
as well as feature parity with other New Relic agents.
* Fix incorrect application of conditions in sinatra instrumentation
The agent's sinatra instrumentation was causing sinatra's conditions to
be incorrectly applied in some obscure cases. The bug was triggered
when a condition was present on a lower priority route that would match
the current request, except for the presence of a higher priority route.
## v3.5.2 ##
* Simplified process of running agent test suite and documented code
contribution process in GUIDELINES_FOR_CONTRIBUTING.
## v3.5.1 ##
* Enabling Memory Profiling on Lion and Mountain Lion
The agent's list of supported platforms for memory profiling wasn't correctly checking
for more recent versions of OS X.
* Fixed an arity issue encountered when calling newrelic_notice_error from Rails applications.
* End user queue time was not being properly reported, works properly now.
* Server-side configuration for ignoring errors was not being heeded by agent.
* Better handling of a thread safety issue.
Some issues may remain, which we are working to address, but they should be gracefully handled
now, rather than crashing the running app.
* Use "java_import" rather than "include_class" when require Java Jars into a JRuby app.
Thanks to Jan Habermann for the pull request
* Replaced alias_method mechanism with super call in DataMapper instrumentation.
Thanks to Michael Rykov for the pull request
* Fixed the Rubinius GC profiler.
Thanks to Dirkjan Bussink
* Use ActiveSupport.on_load to load controller instrumentation Rails 3.
Thanks to Jonathan del Strother
* Reduce the number of thread local reference in a particular high traffic method
Thanks to Jeremy Kemper
## v3.5.0.1 ##
* (Fix) Due to a serious resource leak we have ended support for versions of Phusion Passenger
older than 2.1.1. Users of older versions are encouraged upgrade to a more recent version.
## v3.5.0 ##
* (Fix) RUM Stops Working After 3.4.2.1 Agent Upgrade
v3.4.2.1 introduced a bug that caused the browser monitor auto instrumentation
(for RUM) default to be false. The correct value of true is now used
* When the Ruby Agent detects Unicorn as the dispatcher it creates an INFO level log message
with additional information
To help customers using Unicorn, if the agent detects it (Unicorn) is being used as the
dispatcher an INFO level log message it created that includes a link to New Relic
online doc that has additional steps that may be required to get performance data reporting.
* (Fix) In version 3.4.2 of the Ruby Agent the server side value for Apdex T was disregarded
With version 3.4.2 of the agent, the value set in the newrelic.yml file took precedence over the
value set in the New Relic UI. As of version 3.5.0 only the value for Apdex T set in the
New Relic UI will be used. Any setting in the yaml file will be ignored.
* Improved Error Detection/Reporting capabilities for Rails 3 apps
Some errors are missed by the agent's exception reporting handlers because they are
generated in the rails stack, outside of the instrumented controller action. A Rack
middleware is now included that can detect these errors as they bubble out of the middleware stack.
Note that this does not include Routing Errors.
* The Ruby Agent now logs certain information it receives from the New Relic servers
After connecting to the New Relic servers the agent logs the New Relic URL
of the app it is reporting to.
* GC profiling overhead for Ruby 1.9 reduced
For Ruby 1.9 the amount of time spent in GC profiling has been reduced.
* Know issue with Ruby 1.8.7-p334, sqlite3-ruby 1.3.0 or older, and resque 1.23.0
The Ruby Agent will not work in conjunction with Ruby 1.8.7-p334, sqlite3-ruby 1.3.3
or earlier, and resque 1.23.0. Your app will likely stop functioning. This is a known problem
with Ruby versions up to 1.8.7-p334. Upgrading to the last release of Ruby 1.8.7
is recommended. This issue has been present in every version of the agent we've tested
going back for a year.
### previous versions ###
## v3.4.2.1 ##
* Fix issue when app_name is nil
If the app_name setting ends up being nil an exception got generated and the application
wouldn't run. This would notably occur when running a Heroku app locally without the
NEW_RELIC_APP_NAME environment variable set. A nil app_name is now detected and an
error logged specifying remediation.
## v3.4.2 ##
* The RUM NRAGENT tk value gets more robustly sanitized to prevent potential XSS vulnerabilities
The code that scrubs the token used in Real User Monitoring has been enhanced to be
more robust.
* Support for Apdex T in server side configuration
For those using server side configuration the Ruby Agent now supports setting
the Apdex T value via the New Relic UI.
* Refactoring of agent config code
The code that reads the configuration information and configures the agent
got substantially reorganized, consolidated, simplified, and made more robust.
## v3.4.1 ##
#### Bug Fixes ####
* Fix edge case in RUM auto instrumentation where X-UA-Compatible meta tag is
present but </head> tag is missing.
There is a somewhat obscure edge case where RUM auto instrumentation will
crash a request. The issue seems to be triggered when the X-UA-Compatible
meta tag is present and the </head> tag is missing.
* Fixed reference to @service.request_timeout to @request_timeout in
new_relic_service.rb. (Thanks to Matthew Savage)
When a timeout occurred during connection to the collector an "undefined
method `request_timeout' for nil:NilClass'" would get raised.
* preserve visibility on traced methods.
Aliased methods now have the same visibility as the original traced method.
A couple of the esoteric methods created in the process weren't getting the
visibility set properly.
* Agent service does not connect to directed shard collector after connecting
to proxy
After connecting to collector proxy name of real collector was updated, but
ip address was not being updated causing connections to go to the proxy.
Agent now looks up ip address for real collector.
* corrupt marshal data from pipe children crashing agent
If the agent received corrupted data from the Reqsue worker child agent
it could crash the agent itself. fixed.
* should reset RubyBench GC counter between polls
On Ruby REE, the GC profiler does not reset the counter between polls. This
is only a problem if GC could happen *between* transactions, as in, for
example, out-of-band GC in Unicorn. fixed.
v3.4.0.1
* Prevent the agent from resolving the collector address when disabled.
* Fix for error collector configuration that was introduced during beta.
* Preserve method visibility when methods are traced with #add_method_tracer and #add_transaction_tracer
v3.4.0
* Major refactor of data transmission mechanism. This enabled child processes to send data to parent processes, which then send the data to the New Relic service. This should only affect Resque users, dramatically improving their experience.
* Moved Resque instrumentation from rpm_contrib to main agent. Resque users should discontinue use of rpm_contrib or upgrade to 2.1.11.
* Resolve issue with configuring the Error Collector when using server-side configuration.
v3.3.5
* [FIX] Allow tracing of methods ending in ! and ?
* [PERF] Give up after scanning first 50k of the response in RUM
auto-instrumentation.
* [FIX] Don't raise when extracting metrics from SQL queries with non UTF-8 bytes.
* Replaced "Custom/DJ Locked Jobs" metric with new metrics for
monitoring DelayedJob: queue_length, failed_jobs, and locked_jobs, all under
Workers/DelayedJob. queue_length is also broken out by queue name or priority
depending on the version of DelayedJob deployed.
