Windows clustering

[bkejser]

Hi

I'd like to monitor drive space on a Windows cluster (i.e. two servers connected to a fiber channel SAN and using the Windows clustering service). Does Cacti support this?

[BSOD2600]

Sure.

Find out how to monitor the data and then report the numbers back to Cacti.

I know this is outside of the realm of Cacti but how could I tell what a Windows server exposes over SNMP? Does Microsoft provide any tools to view what data SNMP exposes?

[BSOD2600]

Either use net-snmp snmpwalk or GetIf. These are the two simple free tools I've used to interrogate devices.

MS doesn't really use SNMP much these days for monitoring. It's all about wmi/perf counters. snmp-informant exposes/translates a lot of these counters to SNMP. otherwise, you'll have to write scripts to harvest the data out for Cacti.

Hi

How would I use GetIf to list the available storage devices?

Thanks

To kind of go back to the original question: Yes because cacti doesn't care if the disks are clustered.

We have a number of failover clusters where I work and we monitor them for all sorts of performance stats, including disk space.

It's just a matter of creating a Cacti host for the cluster group ('service or application' in Windows 2008 R2) and tell cacti to graph only the disks that belong to that group.

I'll say here that the only caveat is that when the groups move to another node, you'll probably have to re-index the data source so the graphs keep working. I've tried using all 2 re-index methods to automatically pick up a failover, but they don't really seem to work properly.
