3.4 .4 . Database Attributes under cn=database, cn=monitor, cn=ldbm database, cn=plugins,
cn=config
The attributes in this tree node entry are all read-only, database performance counters. All of the values
for these attributes are 32-bit integers, except for entrycachehits and entrycachetries.
If the nsslapd-counters attribute in cn=config is set to on, then some of the counters kept by the
Directory Server instance increment using 64-bit integers, even on 32-bit machines or with a 32-bit
version of Directory Server. For the database monitoring, the entrycachehits and entrycachetries
counters use 64-bit integers.
NOTE
The nsslapd-counters attribute enables 64-bit support for these specific database and server
counters. The counters which use 64-bit integers are not configurable; the 64-bit integers are
either enabled for all the allowed counters or disabled for all allowed counters.
