Configuration

This monitor provides the following on configuration:

IntervalSeconds: How frequently the monitor is run (in sec)

NumSamples: How many times the monitor has to be over the threshold to generate an alertThresholdWarnSec: The warning threshold in sec.

ThresholdErrorSec: The error threshold in sec.

Causes

There can be several causes to a poor performance of an LDAP query. Use the inline tasks provided below to diagnose the problem.

Tasks Check current LDAP response time

Check top processes currently using the processor
