Microsoft Cluster resource monitoring

[Uday Kumar]

Hi All,

can we able to provide monitoring for Microsoft Cluster resources ?
If so please help us to get the right plug-ins and method of monitoring.

Where we already monitoring the cluster Nodes.

Have you looked at our Nagios Exchange site? There are a lot of plugins that may be useful, such as these:

Hi Team,

Thanks for providing links.
We have used check_microsoft_cluster.vbs in windows 2008 server and we are getting correct output.

But when we used same script for 2012 server , we are getting the error which is attached below. can we use same script for 2012 servers ?
If so, please help us here to sort out the issue or let us know if there is any other available script for 2012 servers.

The file in your error is for check_files.vbs, this doesn't appear to be the same script as check_microsoft_cluster.vbs. There isn't even an occurence of the word 'NagiosPlugin' in it.

Code: Select all

Hi Kennedy,

Thanks for your inputs.

For 2008 server, script is working fine in remote host.

But when we are calling from Nagios, we are facing below issue.

[root@ libexec]# ./check_nrpe -H xxxxxxxxx -c check_mscs -a CLRES
No handler for command: check_mscs


Please find the attached Nsclient file

[dwhitfield]

Is check_files.vbs calling check_microsoft_cluster.vbs ? If so, could you try running check_microsoft_cluster.vbs directly?

[Uday Kumar]

HI,

The problem facing for 2008 servers got fixed and we are able to monitor cluster resources of those servers.

But when we use same microsoft_cluster.vbs in 2012 server , we are getting the below attached error.
Can you please assist us here.

[rkennedy]

Per this post, it will not work in 2012 so you would need to re-write the plugin, or look for one that will work on 2012.
