Clustered services

Hi folks, how are you monitoring your clustered environment? Specifically Windows 2003/2008 with MS Clustering or using a NLB. I have APM's applied to servers in a cluster but of course, the passive node shows down because the active node has the services. Any tips or suggestions?

Thanks!

This is what I do for SQL clusters so it may apply for you. I have SQL clusters that consist of two physical nodes, and numerous virtual instances. On the physical nodes I monitor the things that are hard tied to the physical boxes (CPU, MEM, C & D Drive, Event log entries). On the virtual instances I monitor the things that can move with a cluster failover (services, mount points, performance queries). Since in the event of a failover the virtual IP never goes down all the services remain tied to that box.

I'm doing this on 10 different clusters and it seems to work very effectively. Like I said I know this is SQL but the principals should be the same.

's approach is same as SolarWinds official recommendation. In addition to monitoring as outlined above SAM includes templates for Monitoring Windows Network Load Balancing and Windows Failover Clusters so you can be alerted to failovers etc.

Thank you for the tips!

We have just recently ran into this problem as well and we also implemented the solution that has suggested and it seems to work very well.

I have these failover clusters in my environment. I.E. {Member1, Member2, VIP} I am monitoring Member1 and Member2 with Agents (not WMI or SNMP). By what method should I be monitoring the VIP?

WMI would be preferred

but is it required? WMI is not an option at this point in this environment. CAN it be done with Agent?

Thanks so much! Everyone says "Add the VIP" but nobody tells you what to pick for polling method! I am using agents and unable to get VIP to work. Looks like I need to open up ports other than the agent ports (i.e. WMI or other non-agent choice).
