Use this Knowledge Script to monitor the number of groups in a domain or organizational unit. This script raises an event if the number of groups exceeds the threshold you set.
Active Directory domain or organizational unit (OU)
To monitor OUs with this script, specify organizationalUnit in the Classes to include parameter of the Discovery_ActiveDS Knowledge Script.
When run on an OU, this script monitors all groups in that OU and any child OUs. The total number of groups for an OU consists of all groups in the OU and in any child OUs.
When you run this script on a domain, the domain and all child OUs will show a job is running. However, when the script is run on a domain, the script runs only on the domain and not on the child OUs.
The default interval for this script is Every 24 hours.
