Table 13.7. General Information (Database)
Performance Metric Current Total
Read-Only Status Shows whether the database is currently in
read-only mode. The database is in read-only
mode when the nsslapd-readonly attribute
is set to on.
Entry Cache Hits The total number of successful entry cache
lookups. That is, the total number of times the
server could process a search request by
obtaining data from the cache rather than by
going to disk.
Entry Cache Tries The total number of entry cache lookups since
the directory was last started. That is, the total
number of search operations performed
against the server since server startup.
Entry Cache Hit Ratio Ratio that indicates the number of entry cache
tries to successful entry cache lookups. This
number is based on the total lookups and hits
since the directory was last started. The
closer this value is to 100%, the better.
Whenever a search operation attempts to find
an entry that is not present in the entry cache,
the directory has to perform a disk access to
obtain the entry. Thus, as this ratio drops
towards zero, the number of disk accesses
increases, and directory search performance
drops. To improve this ratio, increase the
number of entries that the directory maintains
in the entry cache by increasing the value of
the Maximum Entries in Cache attribute.
See Section 2, “Tuning Database
Performance” for information on changing this
value using the Directory Server Console.
Current Entry Cache Size (in Bytes) The total size of directory entries currently
present in the entry cache.
Maximum Entry Cache Size (in Bytes) The size of the entry cache maintained by the
directory. This value is managed by the
Maximum Cache Size setting. See Section 2,
