Cache stats

OpenKM takes advantage of cached objects for fast retrieving data.

For example the users and roles list, when application is configured to working with LDAP, are cached to reduce the traffic between application and LDAP server.

The associated cached name for LDAP are:

  • com.openkm.cache.ldapPrincipalAdapter.general
  • com.openkm.cache.ldapPrincipalAdapter.name

Also cache can be used to collect data useful to find out configuration parameters changes  needed for better application perfomance. For this purpose the application comes with a cache audit trail.

Cache stats are shown in a table structure:
