I this correct ? I currently have a secondary nameserver which is effectively offline as that VM-Host is down. All my others are up. Yet "monitor" doesn't show a problem ? even with refresh... Is this correct ?
Yes, that's correct. The monitor shows when a service is down but not when a complete server is not updating its status anymore. Currently you can see an outdated status only by looking at the timestamp of the data. It is planned to add a notification when status data becomes outdated which is an indication that a complete server is offline.
Thanks Till for the fast response.... I happen to be looking at http://www.zabbix.com/ for a client......
