Capture and persist key system events in Jenkins—such as job configurations, builds, and security changes—by installing the Audit Trail plugin. This setup writes audit logs to a rotating file on your Jenkins controller, helping you meet compliance and troubleshooting needs.

​
1. Install the Audit Trail Plugin

The Audit Trail plugin supports multiple destinations for logging: local files, console, syslog, or Elasticsearch.
Logger DestinationUse CaseConfiguration Example
Log File (Daily Rotation)Store events in timestamped files/var/log/jenkins/audit-%g.log
ConsoleQuick debugging via Jenkins system logs—
SyslogCentralized log managementConfigure host and port in plugin settings
ElasticsearchAnalytics and long-term retentionProvide cluster URL and index name
You must have Jenkins Administrator privileges to install plugins and modify system configurations.
  1. Navigate to Manage Jenkins → Manage Plugins.
  2. Select the Available tab, search for Audit Trail, check the box, and click Install without restart.
  3. When installation finishes, go to Manage Jenkins → Configure System to set up your first logger.

​
2. Configure an Audit Trail Logger

Scroll to the Audit Trail section and add a new logger for daily-rotated log files.
  1. Click Add → Log File (Daily Rotation).
  2. In Log File Pattern, enter: 
    /var/log/jenkins/custom-audit-%g.log
  3. Keep other options at their default values, then click Apply and Save.
The image shows a Jenkins system configuration page with options for adding loggers and configuring audit trails. There are dropdown options for different logging methods and checkboxes for logging build triggers and credential usage.
Ensure the Jenkins user has write permissions to /var/log/jenkins. Otherwise, audit entries will fail silently.

​
3. Verify Audit Logging

Trigger actions in Jenkins and inspect the generated log files:
  1. Open an existing job (e.g., Monitor Jenkins), click Configure, make a trivial change, then Apply & Save.
  2. Click Build Now to start a new build.
On the controller host, list and inspect the audit logs: 
# List rotated files
ls -l /var/log/jenkins
Example output: 
total 12
-rw-r--r-- 1 jenkins jenkins 2016 Nov 10 14:10 custom-audit-0.log-2024-11-10
-rw-r--r-- 1 jenkins jenkins   24 Nov 10 14:10 custom-audit-0.log-0.lck
View recent entries: 
cat /var/log/jenkins/custom-audit-0.log-2024-11-10
Sample log lines:

These entries confirm both configuration changes and build executions are being audited.

4. Adjust Log Rotation Settings

To control retention, modify the Max History for your daily rotation:
  1. Return to Manage Jenkins → Configure System.
  2. In Audit Trail, click Edit on your log-file entry.
  3. Set Max History (for example, 10 files).
  4. Click Apply and Save.
The image shows a Jenkins system configuration page with options for setting log file parameters and URL patterns to log. There are buttons for adding a logger, saving, and applying changes.
After saving, perform another job configuration or build and verify the new entries: 
tail -n 5 /var/log/jenkins/custom-audit-0.log-2024-11-10

​
Conclusion

You have successfully installed and configured the Jenkins Audit Trail plugin to record all vital operations in daily-rotated log files. Extend this setup to syslog or Elasticsearch for centralized analysis and long-term storage.
