monitoring

We use nagios for our network monitoring and I'm going to start knocking out some nagios plugins for checking if servers are responding and more interestingly, to check replication.I was wondering what other people use here for monitoring.Sergio.

Directory Server does deliver some tools to monitor replication.But most of the customers write their own monitoring tools over LDAP.Regards,Ludovic.
