Jenkins

A Jenkins plugin for automatically forwarding metrics, events, and service checks to a Datadog account.

Note: The Jenkins CI plugin page for this plugin references this documentation.

Setup

Installation

This plugin requires Jenkins 2.303.3.

For older versions of Jenkins (i.e 1.632+), you can find the 1.2.0 version of the plugin here.

This plugin can be installed from the Update Center (found at Manage Jenkins -> Manage Plugins) in your Jenkins installation:

1. Select the Available tab, search for Datadog, and select the checkbox next to Datadog Plugin.
2. Install the plugin by using one of the two install buttons at the bottom of the screen.
3. To verify the plugin is installed, search for Datadog Plugin on the Installed tab.

Continue below for configuration.

Note: If you see an unexpected version of the Datadog Plugin, run Check Now from the Manage Jenkins -> Manage Plugins screen.

Configuration

There are two ways to configure your plugin to submit data to Datadog:

• RECOMMENDED: Using a Datadog Agent that acts as a forwarder between Jenkins and Datadog.
  • When using a DogStatsD server instead of a full Datadog Agent, only metrics and events are supported.
  • For data submitted from an external host, the Datadog Agent requires the following configuration: dogstatsd_non_local_traffic: true and apm_non_local_traffic: true. This can be configured using the datadog.yaml configuration file.
• Sending data directly to Datadog through HTTP.
  • The HTTP client implementation used is blocking with a timeout duration of 1 minute. If there is a connection problem with Datadog, it may slow your Jenkins instance down.
  • This method does not currently support trace collection to be used with the “CI Visibility” product.

The configuration can be done from the plugin user interface with a Groovy script, or through environment variables.

Plugin user interface

To configure your Datadog Plugin, navigate to the Manage Jenkins -> Configure System page on your Jenkins installation. Once there, scroll down to find the Datadog Plugin section:

HTTP forwarding

1. Select the radio button next to Use Datadog API URL and Key to report to Datadog (selected by default).
2. Paste your Datadog API key in the API Key textbox on the Jenkins configuration screen. If you would like to store your API key with the Credentails Manager, create a Credential for the API key and select that credential in the Datadog API Key (Select from Credentials) dropdown.
3. Test your Datadog API key by using the Test Key button on the Jenkins configuration screen directly below the API key textbox.
4. (optional) Enter the hostname of the Jenkins server in the Advanced tab to include it with the events.
5. (optional) Enter your Datadog Log Intake URL and select “Enable Log Collection” in the Advanced tab.
6. Save your configuration.

Datadog Agent forwarding

1. Select the radio button next to Use the Datadog Agent to report to Datadog.
2. Specify your Datadog Agent hostname and port.
3. (optional) Enter the hostname of the Jenkins server in the Advanced tab to include it with the events.
4. (optional) Enter your Log Collection Port, configure log collection in the Datadog Agent, and select “Enable Log Collection”.
5. (optional) Enter your Trace Collection Port and select “Enable CI Visibility”, optionally configuring your CI Instance name.
6. Save your configuration.

Groovy script

Configure your Datadog plugin to forward data through HTTP or DogStatsD using the Groovy scripts below. Configuring the plugin this way might be useful if you’re running your Jenkins Master in a Docker container using the official Jenkins Docker image or any derivative that supports plugins.txt and Groovy init scripts.

HTTP forwarding using Groovy

import jenkins.model.*
import org.datadog.jenkins.plugins.datadog.DatadogGlobalConfiguration

def j = Jenkins.getInstance()
def d = j.getDescriptor("org.datadog.jenkins.plugins.datadog.DatadogGlobalConfiguration")

// If you want to use Datadog API URL and Key to report to Datadog
d.setReportWith('HTTP')
d.setTargetApiURL('https://api.datadoghq.com/api/')
d.setTargetApiKey('<DATADOG_API_KEY>')

// Customization, see dedicated section below
d.setExcluded('job1,job2')

// If you want to collect logs
d.setLogIntakeUrl('https://http-intake.logs.datadoghq.com/v1/input/')

// Save config
d.save()

Datadog Agent forwarding using Groovy

import jenkins.model.*
import org.datadog.jenkins.plugins.datadog.DatadogGlobalConfiguration

def j = Jenkins.getInstance()
def d = j.getDescriptor("org.datadog.jenkins.plugins.datadog.DatadogGlobalConfiguration")

d.setReportWith('DSD')
d.setTargetHost('localhost')
d.setTargetPort(8125)

// If you want to collect logs
d.setTargetLogCollectionPort(10518)
d.setCollectBuildLogs(true)

// If you want to enable CI Visibility
d.setTargetTraceCollectionPort(8126)
d.setEnableCiVisibility(true)
d.setCiInstanceName("jenkins")

// Customization, see dedicated section below
d.setExcluded('job1,job2')

// Save config
d.save()

Environment variables

Configure your Datadog plugin using environment variables with the DATADOG_JENKINS_PLUGIN_REPORT_WITH variable, which specifies the report mechanism to use.

HTTP forwarding using environment variables

1. Set the DATADOG_JENKINS_PLUGIN_REPORT_WITH variable to HTTP.
2. Set the DATADOG_JENKINS_PLUGIN_TARGET_API_URL variable, which specifies the Datadog API endpoint (defaults to https://api.datadoghq.com/api/).
3. Set the DATADOG_JENKINS_PLUGIN_TARGET_API_KEY variable, which specifies your Datadog API key.
4. (optional) Set the DATADOG_JENKINS_PLUGIN_TARGET_LOG_INTAKE_URL variable, which specifies the Datadog Log Intake URL (defaults to https://http-intake.logs.datadoghq.com/v1/input/).

Datadog Agent forwarding using environment variables

1. Set the DATADOG_JENKINS_PLUGIN_REPORT_WITH variable to DSD.
2. Set the DATADOG_JENKINS_PLUGIN_TARGET_HOST variable, which specifies the DogStatsD server host (defaults to localhost).
3. Set the DATADOG_JENKINS_PLUGIN_TARGET_PORT variable, which specifies the DogStatsD server port (defaults to 8125).
4. (optional) Log Collection:
   • Enable log collection in the Datadog Agent.
   • Set the DATADOG_JENKINS_PLUGIN_TARGET_LOG_COLLECTION_PORT variable, which specifies the Datadog Agent log collection port.
   • Set the DATADOG_JENKINS_PLUGIN_COLLECT_BUILD_LOGS variable to true in order to enable log collection (disabled by default).
5. (optional) CI Visibility (trace collection):
   • Set the DATADOG_JENKINS_PLUGIN_TARGET_TRACE_COLLECTION_PORT variable, which specifies the Datadog Agent trace collection port (defaults to 8126).
   • Set the DATADOG_JENKINS_PLUGIN_ENABLE_CI_VISIBILITY variable to true in order to enable CI Visibility (disabled by default).
   • Set the DATADOG_JENKINS_PLUGIN_CI_VISIBILITY_CI_INSTANCE_NAME variable, which specifies the name of the Jenkins instance for CI Visibility (defaults to jenkins).

Additionally, you can use the standard Datadog environment variables:

• Set the DD_AGENT_HOST variable, which specifies the Datadog Agent host.
• Set the DD_AGENT_PORT variable, which specifies the DogStatsD server port.
• Set the DD_TRACE_AGENT_PORT variable, which specifies the Datadog Agent trace collection port.
• Set the DD_TRACE_AGENT_URL variable, which specifies the Datadog Agent URL to send traces. When set this takes precedence over DD_AGENT_HOST and DD_TRACE_AGENT_PORT.

The environment variables with the DATADOG_JENKINS_PLUGIN namespace take precedence over the standard Datadog environment variables.

Logging

Logging is done by utilizing the java.util.Logger, which follows the best logging practices for Jenkins. To obtain logs, follow the directions in the Jenkins logging documentation. When adding a logger, all Datadog plugin functions start with org.datadog.jenkins.plugins.datadog. and the function name you are after should autopopulate. As of this writing, the only function available was org.datadog.jenkins.plugins.datadog.listeners.DatadogBuildListener.

Customization

Pipeline customization

The Datadog plugin adds a “datadog” step that provides some configuration option for your pipeline-based jobs. In declarative pipelines, add the step to a top-level option block like so:

pipeline {
    agent any
    options {
        datadog(collectLogs: true, tags: ["foo:bar", "bar:baz"])
    }
    stages {
        stage('Example') {
            steps {
                echo "Hello world."
            }
        }
    }
}

In scripted pipeline, wrap the relevant section with the datadog step like so:

datadog(collectLogs: true, tags: ["foo:bar", "bar:baz"]){
  node {
    stage('Example') {
      echo "Hello world."
    }
  }
}

Note: Pipeline customizations are only registered after a job has started. Tags specified in pipeline customization will not be associated with jenkins.job.started.

Global customization

To customize your global configuration, in Jenkins navigate to Manage Jenkins -> Configure System then click the Advanced button. The following options are available:

Job customization

From a job specific configuration page:

Data collected

This plugin is collecting the following events, metrics, and service checks:

Events

Default events type

NOTE: event_type is always set to default for above events and metrics.

Systems events type

NOTE: event_type is always set to system for above events and metrics.

Security events type

NOTE: event_type is always set to security for above events and metrics.

Metrics

Log Collection for Agents

Note: This configuration only applies to those using the Datadog Agent configuration.

1. Collecting logs is disabled by default in the Datadog Agent, enable it in your datadog.yaml file:

   logs_enabled: true
   

2. To collect Jenkins logs, create a custom log source file for your Agent by creating a conf.yaml inside conf.d/jenkins.d with the following:

   logs:
     - type: tcp
       port: <PORT>
       service: <SERVICE>
       source: jenkins
   

3. In Jenkins, submit the port you specified above as the Log Collection Port. You can set this using environment variables, a Groovy script, or the Jenkins UI.

4. Restart the Agent.

Service checks

Build status jenkins.job.status with the default tags: : jenkins_url, job, node, user_id

Issue tracking
