Read-Only Status

Shows whether the database is currently in

 

read-only mode. The database is in read-only

 

mode when the nsslapd-readonlyattribute

 

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,
