This plugin saves a copy of the configuration file of a job (
config.xml) for every change made and of the system configuration. You can also see what changes have been made by which user if you configured a security policy.
The plugin also provides an overview page of all changes. You can find it under
<jenkins_url>/jobConfigHistory or reach it via links in the sidepanel of the main and the system configuration pages. The overview page lists at first only changes made to the system configuration (for performance reasons), but there are links to view either all job configuration histories or just the deleted jobs or all kinds of configuration history entries together (which may take some time to load, depending on the number of jobs in your instance).
It is also possible to get a side-by-side view of the differences between two configurations and to restore an old version of a job's configuration. (The latter is only available for jobs, not for system changes.) However, if you restore an older version of the config file and the new version contains fields that were not present in the older version, the restored version will still contain these fields, although they were not present in the original.
With the 1.x versions of this plugin, the job configuration history data used to be stored with each job (JENKINS_HOME/jobs/JOBNAME/config-history), whereas the system configuration history was stored in an extra directory under JENKINS_HOME. As of version 2.0, both types of configuration history data are now to be found in one directory under JENKINS_HOME. The default location for this folder is JENKINS_HOME/config-history.
Now there are two possible scenarios:
If you did not use the default root history directory of the 1.x version, but set it to an individual path on the Jenkins configuration page, the 2.x versions of the plugin should still be able to find and display the data correctly.
However, if you did not change the path and used the default root history directory, your job configuration data is stored with each job, where the 2.x versions of the plugin will not find it any longer. If you want the plugin to list the job configuration history again, you have to move the data manually from JENKINS_HOME/jobs/JOBNAME/config-history to JENKINS_HOME/config-history/jobs/JOBNAME.
This can be done with a script like the following:
If you use this plugin together with the Global Build Stats Plugin you should add
global-build-stats to the excludes in the System configuration exclude file pattern section of this plugin in Configure System page. Fixed in version 1.9 of the plugin.
