Cluster Storage on Windows.

[antorres]

Hi there.

I've been searching for a way to monitor a Cluster Storage mounted on windows, and I cannot make it work. I've tried all plugins available but with no results.

My client said to me, that back in time, when they used tivoli, it only required the IP and some sort of authentication (his words) and he used to see all the hosts connected to the cluster, as well as the virtual machines running on those hosts.

First, I've searched for a Nagios configuration wizard, then at the Nagios exchange for plugins but still cannot make it work.

Does Nagios have an official plugin for this? How did you guys workaround this problem in the past? What should I do in order to make it well?

Any help will be very helpful.

Thank you all in advance.

Best Regards.

This plugin checks remaining space of a Cluster Shared Volume (in HyperV):

My understanding is that you'd like to keep track of when members of a Cluster Storage drop out of the cluster? That should be doable via Powershell and the Get-ClusterResource cmdlet:

Though some Powershell know-how would be required.

I have already try that , but that's just free space remaining, and it doesn't work for me

I got "error cannot divide by 0".
Tomorrow I will be trying one more time and I going to paste here my results.

Thank you very much for your kind help.

Hi there.

Following with the thread, the command on power shell follow like these.

Code: Select all

PS C:\Program Files\NSClient++\scripts> .\check_csv_freespace.ps1 -n Datos -w 80 -c 90
OK - Datos total: 836GB, used: 48GB (5%), free: 788GB (94%) | 'Datos used_space'=48Gb;668;752;0;836

but I've had encounter a lot of troubles in order to send the answer to nagios.

my NSC.ini file is like these.

is there anything wrong below?

Try this maybe? Then run it from check_nrpe again and let us know.

Code: Select all

[/settings/external scripts/wrapped scripts]
check_csv_freespace=scripts\check_csv_freespace.ps1 -n Datos -w 70 -c 85

[/settings/external scripts/scripts]
check_csv_freespace=cmd /c echo scripts\\check_csv_freespace.ps1 -n $ARG1$ -w $ARG2$ -c $ARG3$ | powershell.exe -command -
