Statistics related to LDAP operations
About this task
Statistics calculation begins at LDAP service startup.
Table 1. LDAP connections statistics
Statistics for network activity on the LDAP service ports
The following statistics relate to network activity over the LDAP service ports since Domino® server startup. These statistics can reflect network activity that does not involve the LDAP protocol, for example activity resulting from telnet requests.
Table 2. LDAP network statistics
LDAP.Search.Longest statistics
This set of statistics allows administrators to quickly identify slow LDAP search patterns. Often it is the search pattern, not every search instance, that determines the overall efficiency of a Domino LDAP search. LDAP applications search by reusing a limited set of search patterns, but with different values. The LDAP.Search.Longest statistics are performance statistics that provide non-disruptive detection of slow LDAP search patterns, and reveal the slowest search patterns used in LDAP searches.
All four sets of statistics are indexed in parallel. Therefore, information about the slowest search patterns has a statistic name suffix of .01, the second slowest has .02, and so on. This yields statistics names such as LDAP.Search.Longest.Pattern.01 and LDAP.Search.Longest.AverageTime.01.
After identifying slow search patterns, (and depending upon the LDAP application), application administrators are then able to adjust their LDAP applications to substitute search filters that the Domino LDAP server can service more quickly.
Table 3. LDAP longest search time statistics
LDAPMaxLongestSearchCount and LDAPMinLongestSearchTime are two NOTES.INI variables you can use to configure how LDAP.Search.Longest statistics are maintained.
