Nagios is a powerful service monitoring tool that is easily extensible using scripts and programs of nearly any language. So we decided to write a short bash script that helps us to monitor the Identity Manager synchronization between our eDirectory trees.
This short script uses ldap to modify user objects that are synchronized between the trees to check attribute synchronization as well as password synchronization.
With this solution we are able to get a end to end monitoring for that process and depending on the notification configuration of Nagios we will be informed quickly if there is a problem.
There is a drawing about how this works on the Nagios Exchange web page.
You will find it following the download link above together with the script.
