To Monitor Entry Cache

For tuning purposes, you might want to check the entry cache for one or more suffixes. Use this procedure to view the entry cache levels.

You can use DSCC to perform this task. For information, see Directory Service Control Center Interface and the DSCC online help.

Monitor entry cache.

$ ldapsearch -h host -p port -D cn=admin,cn=Administrators,cn=config -w - \ -b "cn=monitor,cn=db-name,cn=ldbm database,cn=plugins,cn=config" "(objectclass=*)"

If the entry cache for a suffix is large enough to hold most of the entries in the suffix and if the cache is primed, the hit ratio (entrycachehitratio) should be high.

If you have primed the cache, you will see that as the previously empty entry cache fills, entry cache size (currententrycachesize) approaches the maximum entry cache size (maxentrycachesize). Ideally, the size in entries (currententrycachecount) should be either equal to or very close to the total number of entries in the suffix (ldapentrycachecount).
