Audit logging
GitHub Enterprise keeps logs of audited user, organization, repository, and system events. Logs are useful for debugging and internal and external compliance.
For a full list, see "Audited actions." For more information on finding a particular action, see "Searching the audit log."
Push logs
Every Git push operation is logged. For more information, see "Viewing push logs."
System events
All audited system events, including all pushes and pulls, are logged to /var/log/github/audit.log. Logs are automatically rotated every 24 hours and are retained for seven days.
The support bundle includes system logs. For more information, see "Providing data to GitHub Support."
Support bundles
All audit information is logged to the audit.log file in the github-logs directory of any support bundle. If log forwarding is enabled, you can stream this data to an external syslog stream consumer such as Splunk or Logstash. All entries from this log use and can be filtered with the github_audit keyword. For more information see "Log forwarding."
For example, this entry shows that a new repository was created.
Oct 26 01:42:08 github-ent github_audit: {:created_at=>1351215728326, :actor_ip=>"10.0.0.51", :data=>{}, :user=>"some-user", :repo=>"some-user/some-repository", :actor=>"some-user", :actor_id=>2, :user_id=>2, :action=>"repo.create", :repo_id=>1, :from=>"repositories#create"}
This example shows that commits were pushed to a repository.
