during the last years we used a open ldap setup with snycrepl for 3 servers. We monitored them with nagios (http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2477.html;d=1) with success.
Now we changed our setup to a n-way master setup and also wish to monitor replication via nagios. Monitoring the contextcsn value seems to not be usefull in a n-way setup.
Any ideas/hints how we can monitor the n-way replication ?
