This performance monitor measures the responsiveness of Active Directory to LDAP (Lightweight Directory Access Protocol) request. It periodically binds to the Domain Controller to measure the response time to a simple LDAP query
This monitor provides the following on configuration:
IntervalSeconds: How frequently the monitor is run (in sec)
FailureThreshold: How many times the monitor has unable to perform the LDAP query before generating an alert
ThresholdWarnSec: The warning threshold in sec.
ThresholdErrorSec: The error threshold in sec.
There can be several causes for this condition. Use the inline tasks provided below to diagnose the problem.
Tasks Check current LDAP response time
Check top processes currently using the processor
