Kubernetes: metrics from the Kube State API

The new kubernetes_state check pulls metrics from the Kubernetes State API.

See #2890, #2984 and omnibus-software-85 for more details.

RPM package for SUSE

The Agent is now available as an RPM package for SUSE. Please follow the instructions on our Agent installation page to use it.

For more details, see related PRs #2900, #2937, omnibus-software-72, dd-agent-omnibus-90

Linux packages: change of ownership of /opt/datadog-agent directory

The Linux packages (deb and rpm) now make the dd-agent user and group own the /opt/datadog-agent folder and its contents when they're installed. This shouldn't cause any change on regular installations of the Agent, but please take this change into account if you customize the ownership/permissions of the /opt/datadog-agent directory or its contents.

For more details, see related PR: dd-agent-omnibus-97

5.8.5 / 07-27-2016

Windows, Linux and Source Install

Details

https://github.com/DataDog/dd-agent/compare/5.8.4...5.8.5

Future rotation of the APT signing key

In preparation for a future rotation of our package signing keys, the 5.8.5 DEB package will, on install, import a new trusted APT key:

pub   4096R/382E94DE 2016-06-29 [expires: 2022-06-28]
uid                  Datadog, Inc <package[@datadoghq][].com>

During the package install, the DEB package will output the following:

Prepare Datadog Agent keys rotation
  Add the new 'Datadog, Inc <package[@datadoghq][].com>' key to the list of APT trusted keys. ... OK

The signing key of the Agent hasn't changed yet but will be switched to this new key in a future release.

Service Discovery

Starting with the 5.8 release, the Datadog Agent ships with service discovery. This feature works for Docker containers and can run on platforms such as Kubernetes, Docker Swarm, and Amazon ECS.

Service discovery makes it possible to define configuration templates for a given Docker image in a configuration store, and to dynamically apply them to new containers on the fly. The Agent will then use these configuration templates combined with container metadata to enable, disable and reconfigure checks dynamically in response to container start/stop events.

For more details on Datadog Agent's Service Discovery, check out the wiki page.

See #2008, #2424, #2426, #2514.

Kong integration

Kong is an open-source management layer for APIs.

The checks collects metrics using /status endpoint part of Kong RESTful API. It retrieves usage information about the node, with some basic information about the connections being processed by the underlying NGINX process, and the number of entities stored in the datastore collections. It also submits a service check to reflect the agent's ability to connect to the instance.

See #2241.

A big thank you @shashiranjan84 !

Spark integration

The Spark check runs from the Master Node and retrieves metrics from YARN's ResourceManager. The collected metrics cover statistics about:

  • Spark Jobs
  • Spark Stages
  • Spark Executors
  • Spark Resilient Distributed Datasets (RDD)

See #2407.

PowerDNS Recursor integration

The PowerDNS Recursor check retrieves metrics using the /servers/localhost/statistics endpoint part of PowerDNS API when the experimental web server is active. The collected metrics cover the Recursor statistics: (outgoing) queries, answers, cache and cache entries. A service check reflects the agent's ability to connect to the instance.

For more details about the metrics collected, check out the PowerDNS documentation about Recursor Statistics.

See #2108, #2490.

A big thank you @AntoCard, @janeczku !

MapReduce & YARN updates

Hadoop MapReduce and YARN integrations have been updated to reduce and consolidate the metrics' tags. In particular:

  • cluster_name tag replaces cluster_id
  • app_name tag replaces app_id

MapReduce metrics have received additional improvements and cleanups:

  • Metric type rate replaces gauge when applicable
  • The following metrics have been removed:
    • mapreduce.job.map.task.progress
    • mapreduce.job.reduce.task.progress

See #2473, #2474, #2487.

Source install: end of Python 2.6 compatibility support

For source installation, the Datadog Agent uses system's Python. Starting with the 5.8.0 release, the Datadog Agent does not enforce compatibility with Python 2.6 anymore and requires Python 2.7. Tests and code sections used to maintain compability have been removed.

Users running a different version of Python on their system are advised to install a packaged version of the Datadog Agent. If you have any questions, please contact our support team support(at)datadoghq(dot)com.

See #2377.

Hadoop integrations (HDFS, MapReduce and YARN checks)

The Agent now includes 4 new checks to monitor Hadoop clusters:

  • 2 HDFS checks (hdfs_namenode and hdfs_datanode) that collect metrics respectively from namenodes and datanodes using the JMX-HTTP API
  • a MapReduce check that collects metrics on the running Mapreduce jobs from the Application Master's REST API
  • a YARN check that collects metrics from YARN's ResourceManager REST API

The existing hdfs check is deprecated and will be removed in a future version of the Agent. Its metric scope is entirely covered by the new hdfs_namenode check.

TCP RTT measurement with go-metro

This new feature is in beta

The Datadog Agent on 64-bit Linux is now bundled with a new component (go-metro) that passively calculates TCP RTT metrics between the agent's host and external hosts, and reports them as system.net.tcp.rtt.avg, system.net.tcp.rtt.jitter and system.net.tcp.rtt through StatsD.

go-metro follows TCP streams active within a certain period of time and estimates the RTT between any outgoing packet with data, and its corresponding TCP acknowledgement.

go-metro runs in its own process. It's disabled by default and can be enabled like a regular check by configuring an /etc/dd-agent/conf.d/go-metro.yaml file and restarting the agent.

For more details on go-metro, check out the project's GitHub page.

Ceph check

The Ceph check retrieves metrics from Ceph's Administration Tool command (ceph).

The check collects metrics from mon_status, status, df detail, osd pool stats and osd perf, and sends a service check reflecting the overall health of the cluster.

See #2264

MySQL

Multiple community-contributed additions to the MySQL check have been consolidated and merged, including:

  • metrics from the performance_schema table on MySQL >= 5.6 (thanks to @ovaistariq)
  • extra metrics on the InnoDB and MyISAM engines, from the Binlog, and from the SHOW STATUS query (thanks to @ovaistariq)
  • several schema-specific metrics, including schema size, schema average query runtime and 95th percentile query execution time (thanks again to @ovaistariq)
  • metrics on the Handler (thanks to @polynomial)
  • Galera-specific performance stats (thanks to @zdannar)
  • Query Cache metrics (thanks to @leucos)
  • a mysql.replication.slave_running service check reflecting the state of the slaves (thanks to @c960657)

Most of these additional metrics are not collected by default but can be enabled in the check's YAML file. See the YAML conf example file for details.

Various bug fixes and improvements have also been implemented:

  • the Agent's connections to MySQL are handled properly to prevent stale connections
  • the replication status is implemented on both the master and the slaves. On the master this status is determined by the Binlog status and the number of slaves.
  • the system metrics of MySQL are retrieved w/o errors on non-linux platforms by using the psutil library
  • the parsing of the MySQL server version is improved

Huge thanks to all our contributors for all these improvements!

See #2116 and #2242

Potential backward incompatibilities

Docker

The dockerized Agent now uses the docker hostname (provided by the Name param from docker info) as its own hostname when available. This means that for hosts running the dockerized Agent the reported hostname may change to this docker-provided hostname.

For reference, the rules followed by the Agent for its hostname resolution are described on this wiki page.

MongoDB

The collect_tcmalloc_metrics parameter in the YAML conf is replaced with the tcmalloc option under additional_metrics. Please refer to the example YAML conf file for more info on the usage of the additional_metrics option.

vSphere

Instead of sending all metrics as gauges, the vSphere integration now checks the types of the metrics as reported by the VMWare module, and sends metrics as rates when applicable.

If you haven't enabled the all_metrics option on the check, the only affected metrics are cpu.usage, cpu.usagemhz, network.received and network.transmitted. If the option is enabled, the additional affected metrics are listed here. The change will affect the values of these metrics.

WMI check

The wmi_check now only supports % as the wildcard character in the filters. The support of * as the wildcard character, which was undocumented, has been dropped.

Kubernetes check

The Kubernetes check retrieves metrics from cAdvisor running under Kubelet.

See #2031

OpenStack check

The OpenStack check is intended to run besides individual hypervisors. It can be scoped to any set of projects living on that host via instance-level config.

At the hypervisor-level it collects:

At the project-level it collects:

Additionally it sends service checks to register the UP/DOWN state of networks discovered by the agent, the locally running hypervisor, and the outward-facing (public || internal) API services of Nova, Neutron and Keystone

Authentication

While the check will run without issues as an admin user, it is recommended to configure a read-only datadog user and configure the check with the corresponding user/password. Instructions on setting up the datadog user + role , as well as the changes required to the policy.json file can be found here

A note on compatibility

Authentication is performed via the password method, and requires Identity API v3 Nova API v2 and v2.1 are supported, with minor additional configuration necessary for v2.

A big thank you @mtougeron !

New WMI module wrapper

Datadog Agent 5.6.0 ships a new built-in lightweight Python WMI module wrapper, built on top of pywin32 and win32com extensions.

Specifications

  • Based on top of the pywin32 and win32com third party extensions only
  • Compatible with Raw* and Formatted Performance Data classes
    • Dynamically resolve properties' counter types
    • Hold the previous/current Raw samples to compute/format new values*
  • Fast and lightweight
    • Avoid queries overhead
    • Cache connections and qualifiers
    • Use wbemFlagForwardOnly flag to improve enumeration/memory performance

\ Raw data formatting relies on the avaibility of the corresponding calculator. Please refer to checks.lib.wmi.counter_type for more information*

Usage
The new WMI module wrapper is used among the following checks to improve speed performances:

  • System
  • WMI

Other checks relying on WMI collection will follow in future versions of Datadog Agent.

[Warning] JMXFetch false-positive bean match & potential backward incompatibilities issues

JMXFetch was illegitimately matching some MBeans attributes when the associated MBean had one of its parameter defined in an instance configuration.

The issue is addressed. As a result, please note that metrics related to false positive bean matches are not reported anymore.

Potential affected checks: ActiveMQ, Cassandra, JMX, Solr, Tomcat.

For more information, please get in touch with support(at)datadoghq(dot)com

Details

https://github.com/DataDog/dd-agent/compare/5.5.1...5.5.2

[WARNING] Datadog Agent not reporting metrics after Daylight Saving Time (DST) ends

This release fixes a bug on servers that are configured in local time instead of UTC Time. If your server's clock is configured to use Daylight Saving Time (DST), the Datadog Agent might stop sending metrics for up to one hour when the Daylight Saving Time ends or until it is restarted after the Daylight Saving Time ends.

We highly recommend to upgrade to this version if your server is configured in local time.

  • New metrics:
    • Network metrics
    • Memory limits
    • Container size (rootfs)
    • Image size
  • Support for labels (convert them into tags). Off by default, uses a list of labels that should be converted.

Backward incompatible changes:

As a consequence, the previous check 'Docker' is now deprecated and will not receive further support.

See #1908

Windows 64bit - Datadog Agent

The Datadog Agent is now available in a 64bit version on Windows. For more information, please visit our Integrations/Agent page.

Flare on Windows

Datadog Agent flare feature makes easy to ship a tarball with logs and configurations to ease agent troubleshooting. Previously exclusive to Linux, it's now available on Windows. For more information, please visit our wiki page.

[Warning] JMX host tag issues & potential backward incompatibilities issues with service check monitors

JMX related checks -c.f. list below- were illegitimately submitting service checks tagged with the host value defined in the YAML configuration file. As it was overriding the agent hostname, with a value often equals to localhost, it was difficult to define and scope monitors based on these service checks.

The issue is addressed. JMX service checks have a new jmx_server tag which contains the YAML configuration host value so it does not replace the actual agent hostname in the host tag anymore.

Warning: these changes affect your JMX-service-checks related existing monitors scoped with the host tag. For more information, please get in touch with support@datadoghq.com

JMX related checks: ActiveMQ, Cassandra, JMX, Solr, Tomcat.

See #66

5.0.5 (Every platform) / 10-31-2014

Details

https://github.com/DataDog/dd-agent/compare/5.0.4...5.0.5

This release fixes a bug on servers that are configured in local time instead of UTC Time. If your server's clock is configured to use daylight saving time, your server might stop sending metrics for up to one hour when the Daylight Saving Time ends or until the Agent is restarted after the Daylight Saving Time ends.

We highly recommend to upgrade to this version if your server is configured in local time.

5.0.0 / 08-22-2014

Details

https://github.com/DataDog/dd-agent/compare/4.4.0...5.0.0

Notes

This is a major version of the Datadog-Agent.

  • On Linux: Packaging of the Agent has changed for RPM and DEB packages.

  • On Windows: This release has multiple fixes, see the list below. Warning: The way CPU metrics are collected has changed and will be more accurate, you might see some changes in the graphs.

What will break ?

  • MySQL integration: If you see this error: OperationalError(2003, 'Can\'t connect to MySQL server on \'localhost\' ((1045, u"Access denied for user \'datadog\'@\'127.0.0.1\'...) the Datadog user will need to be modified from 'datadog'@'localhost' to 'datadog'@'127.0.0.1' (your host IP). You can do this by running:

           $ mysql -p mysql
           # UPDATE user SET Host = '127.0.0.1' WHERE User = 'datadog';
           # FLUSH PRIVILEGES;
    
  • If you were using a custom check that needed python dependencies you will have to reinstall them using the bundled pip:

    sudo /opt/datadog-agent/embedded/bin/pip install YOUR_DEPENDENCY
    
  • Configuring checks in datadog.conf for checks.d is deprecated and won't work anymore. Please configure your checks by editing the yaml files in the conf.d directory.

How to upgrade from 3.0.4 on Debian and Ubuntu

When we released datadog-agent 3.0.4 we made a mistake and messed up the version dependency between packages. As a result, whenever you run apt-get upgrade or apt-get dist-upgrade and 3.0.4 is installed you may get the following error:

E: Couldn't configure pre-depend datadog-agent-base for datadog-agent, probably a dependency cycle.

If that's the case, don't panic: there is a simple fix. Simply run:

sudo apt-get update
sudo apt-get remove datadog-agent
sudo apt-get install datadog-agent

to get the new versions up-and-running.
