Jenkins Usage Statistics

Build Status

These scripts generate various data from existing census JSON files collected by the jenkins.io infrastructure. More specifically:

WHAT


this scipts will create the following files:

  • multiple SVG graphics showing different statistcs about the usage of jenkins

  • a file <plugin-name>.stats.jsonfor every plugin, containing the following data (example: git-plugin - git.stats.json ):

    • name: the name of the plugin (as used in the filename)
    • installations: the number of installations for a given month
    • installationsPercentage: the percentage of installations
    • installationsPerVersion: the number of plugin installations for for each plugin version
    • installationsPercentagePerVersion: the percentage of installations a specifig version of the plugin makes up
  • installations.json: the number of jenkins installations by the jenkins core version

  • capabilities.json: a reverse cumulation of the installations.json to assist plugin developers in choosing base versions for there further plugin development

HOWTO


Data

  1. you need to download the raw data (*.json.gz) from jenkins-ci.org

    $> groovy download.groovy [pwd]

SVG (optional)

  • generate the graphs ... you might have to increase the memory: JAVA_OPTS="-Xmx4000M"
$> export LANG=en
$> groovy generateStats.groovy

The final SVGs will be in [workspace]/target/svg

JSON (optional)

  1. collect the data from the raw json format and store it into a local SQLite database
$> export LANG=en
$> groovy collectNumbers.groovy`
  1. generate the fine grained data set (json) for each plugin

    $> groovy createJson.groovy

The final json files will be in [workspace]/target/stats - these files have to be uploaded to a webserver to make them available for the confluence plugin.

All the scripts can be reexecuted in case a failure happens, e.g. the download will only download the files he needs and collecting the numbers will only happen on the raw data which is not imported yet.
