collectd jenkins Plugin

A Jenkins collectd plugin which users can use to send metrics from Jenkins instances to SignalFx.

Installation

• Checkout this repository somewhere on your system accessible by collectd. The suggested location is /usr/share/collectd/
• Install the Python requirements with sudo pip install -r requirements.txt
• Install the Metrics Plugin in Jenkins. Manage Jenkins > Manage Plugins > Available > Search "Metrics Plugin"
• Configure the plugin (see below)
• Restart collectd

Requirements

• collectd 4.9 or later (for the Python plugin)
• Python 2.7 or later
• Jenkins 1.580.3 or later
• Metrics Plugin(see installation steps)

Configuration

The following are required configuration keys:

• Host - Required. Hostname or IP address of the etcd member, default is 'localhost'
• Port - Required. The port of the jenkins instance, default is '8080'
• MetricsKey - Required. The access key from Manage Jenkins > Configure System > Metrics > ADD. If empty, click Generate

Optional configurations keys include:

• Interval - Interval between metric calls. Default is 10s
• Username - user id with access, if any. Username will require APIToken too
• APIToken - API token from the system configuration in Jenkins. Username > Configure > API Token > Show API Token
• Path - URL prefix to use in the HTTP request
• EnhancedMetrics - Flag to specify whether advanced stats from the /metrics/<MetricsKey>/metrics endpoint are needed. Default is False
• IncludeMetric - Advanced Metrics from the /metrics/<MetricsKey>/metrics endpoint can be included individually
• ExcludeMetric - Advanced Metrics from the /metrics/<MetricsKey>/metrics endpoint can be excluded individually
• Dimension - Add extra dimensions to your metrics
• ExcludeJobMetrics - Flag to specify whether to exclude calls to /json/api for all jobs and builds.

SSL/TLS

• ssl_enabled - True to perform HTTP requests over TLS. Default is False
• ssl_cert_validation - False to skip certificate validation. Default is True

To enable client certificate authentication specify these options:

• ssl_keyfile - path to file
• ssl_certificate - path to file

Provide a custom file that lists trusted CA certificates, required when keyfile and certificate are provided or the server certificate is not signed by a system CA:

• ssl_ca_certs - path to file

From /metrics/<MetricsKey>/metrics only the metrics inside gauges key are representable, if the value is a number. Metrics of type histograms, meter and timer will be skipped over. Check out https://wiki.jenkins.io/display/JENKINS/Metrics+Plugin for description of the metrics.

Note that multiple Jenkins instances can be configured in the same file.
