Audit log

The audit log records the actions performed on the CLC Server. Included are actions like logging in, logging out, import, and the launching and running of analysis tasks. Data management operations such as copying, deleting and adding files are not Server actions and are thus not recorded.

Audit log information is available at:

        Management (Image management_16) | Audit log (Image auditlog_16)

Audit log information is stored in a database. Once a month, and when the CLC Server is started up, entries in the audit log older than 3 months are deleted.

The limit the audit log database can grow to is 64 GB. If a new entry will push the size past this limit, the system will remove some of the oldest entries so that is is possible for newer entries to be added.

Audit information is also written to text-based log files. Upon the first activity on a given date, a new log file called audit.log is created. This file is then used for logging that activity and subsequent Server activities on that day. When this new audit.log file is created, the file that previously had that name is renamed to audit.<actual events date>.log. These log files are retained for 31 days. When the creation of a new audit.log file is triggered, audit log files older than 31 days are checked for and deleted.

The audit log files can be found under the Server installation area under webapps/CLCServer/WEB-INF.

The audit log text files are tab delimited and have the following fields:
