Log file rotation

The file-based audit event handlers let you rotate audit log files, either automatically, based on a set of criteria, or by using a REST call.

To configure automatic log file rotation, set the following properties in your project’s audit.json file:

{
    "class" : "org.forgerock.audit.handlers.json.JsonAuditEventHandler",
    "config" : {
        "fileRotation" : {
            "rotationEnabled" : true,
            "maxFileSize" : 0,
            "rotationFilePrefix" : "",
            "rotationTimes" : [ ],
            "rotationFileSuffix" : "",
            "rotationInterval" : ""
        },

The file rotation properties are described in JSON Audit Event Handler Properties.

If you have enabled file rotation ("rotationEnabled" : true), you can rotate the JSON log files manually for a specific audit event topic, over REST. The following command saves the current access log file with a date and time stamp, then starts logging to a new file with the same base name.

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://localhost:8080/openidm/audit/access?handler=json&_action=rotate"
{
  "status": "OK"
}

If the command is successful, two access.audit.json files display in the openidm/audit directory, for example:

access.audit.json			access.audit.json-2016.10.12-17.54.41

The file with the extension (2016.10.12-17.54.41) indicates that audit logging to this file ended on October 12, 2016, at 5:54:41 pm.

To configure log rotation in the admin UI, click Configure > System Preferences > Audit, and edit the JSON audit event handler (or the CSV audit event handler if you are logging to CSV). You can set all the log rotation properties on this screen.
