The term obsolete refers to any data not needed by the database but still occupying space on it. This unwanted or obsolete data can eventually fill up the disk and decrease the database performance, causing time-consuming database lookups, contention issues and so on. The process of systematically removing this unwanted data from the database is called purging. This process basically involves running the Purger scripts. They are available for all log units stored in the CentraSite Log Database.

Typically, you need the CentraSite Log Database to include only the recent log records. For instance, each CentraSite object will have a number of actions performed on it, and for each action a separate audit log is generated and stored in the CentraSite Log Database. This will increase the size of the CentraSite Log Database dramatically. Failure to purge the excess log records in the database could cause problems. Therefore, the purge interval should be configured as required.

Each time you purge a log unit, the corresponding purging log entry is created and can be viewed in CentraSite Control. For example, when you purge a certain set of policy logs, the corresponding purging log entry is automatically created and will be visible in the Policy Log page.
