several techniques to monitor an LDAP server
LDAP has become the Internet standard directory access protocol, and is used to access everything from DNS zone files to user account information. As companies and software vendors rely more heavily on LDAP directory servers, the need to measure server throughput and performance becomes imperative. This article will cover several tools that can be used to monitor the health and performance of an LDAP directory server, and will explain how ORCA can be used to trend directory server performance over time.
The OpenLDAP server can be configured to provide real time performance statistics through the monitor branch. The currently available statistics include: bytes sent, entries returned to clients, total connections to the server, current active connections, read and write waiters, and individual operation (e.g., read, search, modify) breakdowns. The following example shows the slapd.conf directives required to setup the monitor branch, and limit read access to IP address 192.168.1.8:
access to dn="cn=monitor"
by peername=192.168.1.8 read
by * none
Once the monitor branch is configured, we can view all of the available statistics with the "ldapsearch" utility:
$ ldapsearch -x -b "cn=monitor" -H ldaps://ldap.prefetch.net objectclass=*
We can also retrieve individual statistics by adjusting the search base:
$ ldapsearch -LLL -x -b "cn=Current,cn=Connections,cn=Monitor" -H ldaps://ldap.prefetch.net objectclass=*
