Table 65 Global database cache information
DescriptionTable header
The number of times the server could process a request by obtaining data from the cache rather
than by going to the disk.
Hits
The total number of requests performed on the directory since server startup.Tries
The ratio of cache tries to successful cache hits. The closer this number is to 100%, the better.Hit Ratio
The number of pages read from disk into the cache.Pages Read In
The number of pages written from the cache back to disk.Pages Written Out
The number of read-only pages discarded from the cache to make room for new pages. Pages
discarded from the cache have to be written to disk, possibly affecting server performance. The
lower the number of page evicts the better.

14.5.2 Monitoring the Directory Server from the command line
The Directory Server's current activities can be monitored using LDAP tools such as ldapsearch,
with the following characteristics:
• Search with the attribute filter objectClass=*.
• Use the search base cn=monitor; the monitoring attributes for the server are found in the
cn=monitor entry.
• Use the search scope base.
For example:
ldapsearch -h directory.example.com -p 389 -D "cn=Directory Manager" -w secret
-s base -b "cn=monitor" "(objectclass=*)"
The monitoring attributes for the Directory Server are found in the cn=monitor entry. For
information on searching the Directory Server, see “Using ldapsearch” (page 556).
Monitoring the server's activities using ldapsearch shows the following information:
