collectd python plugin to read out and parse cn=monitor metrics from ldap monitor
python-ldap - should be part of core utils with most linux distros with python
Download the ldap_cn_monitor.py and place it, preferrably in a custom defined diretory to avoid collectd python package clashes e.g. /var/my/collectd/modules/.
when defining the ModulePath "/var/my/collectd/modules/ldap-cn-monitor/" - Do not forget the traling slash.
See example below, if placed in a separate conf file LoadPlugin python is required if not declared in the collectd.conf or elsewhere.
The ldap fqdn or ip.
Either value will work ==> "ldap://fqdn:389" || "ldap://127.0.0.1:389"
Currently you can only define a single host or if using a load balanced URL the metrics will only be run agains the host which has answered the request.
default: ldap://localhost
The base DN against which to perform the ldapsearch
default: "cn=monitor"
The monitor or directory admin - must have cn=monitor read privelleges
default: "cn=Directory Manager"
monitor_admin password
default: "pwd1234"
ldap filter to apply on the query.
Any filter attributes must follow the RFC4515 guidelines and will be appended to the default values which are common across most LDAP implementations.
leave commented out if empty
default: "(|(cn=Work Queue)(cn=JVM*)(cn=HTTP*)(cn=Gauge CPU*)(cn=Active*))"
useful values would be: "(cn=dc_example_dc_com_changes*)"
Attributes to retrieve, again any attributes will be appended to the default list.
The values must a single string with comma separated values inside - sample "foo,bar"
leave commented out if empty
default: ['current-queue-size','current-administrative-session-queue-sizerejected-count','num-worker-threads','num-busy-worker-threads','value','average-connection-duration-millis','total-connections-accepted','total-invocation-count','current-active-connections','average-processing-time-millis','currentReservedMemoryMB','freeReservedMemoryMB','usedReservedMemoryMB','num-operations-in-progress','num-persistent-searches-in-progress']
useful values would be: "record-count,database-size-as-percentage-of-jvm-heap"
