Cache stats

OpenKM takes advantage of cached objects for fast data retrieval.

Tip

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

The associated cached names for LDAP are:

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

The cache can also be used to collect data useful for identifying configuration parameter changes needed for better application performance. For this purpose, the application comes with a cache audit trail.

Cache stats are shown in a table structure:

Cache name Hits Misses Objects Memory hits Memory objects Disc hits Disc misses Disc objects Action

Field	Description	Audit trail required
