[hobbit] Windows Cluster Monitor

[Oliver Bassett]

My current solution for this is pretty messy, but it works for me.

In the below I am assuming that you are going to have the windows bb client
installed on all nodes of the cluster.

Active/Passive:
Since want to know when the services fail over I check to ensure
processes/services are running on the active node, as well as ensuring that
the cluster service is running on both nodes. This let's me know when it
fails over so I can investigate immediately.

I also run a specific application check against the clustered application on
the cluster address to ensure the application itself is up and running. If
it isn't then there is a really serious problem.

Active/Active:
Since I don't do this I can be entirely sure, but this would be easier to
monitor I would think, just ensure that all the services required are
running on all nodes, including the cluster service itself.

I hope this is of some help.

Regards
Oliver Bassett

Subject: [hobbit] Windows Cluster Monitor


Hello All,

Our new director would like to monitor EVERYTHING from BB/Hobbit.  We
have been monitoring our UNIX and Storage Devices for a few years now.
Now that I have windows servers to monitor, I'd like to know if anyone
has a decent way to monitor Windows Clusters?  I had a thought to
monitor by ping each node in the cluster, and the cluster name, ie:

Nodea			- Application Offline
Nodeb			- Application Online
Clustername		- Application Responding @ This address

How would you set up resource (process) monitoring for an Active /
Passive cluster?  Or an Active / Active cluster?  

This is in response to a problem that has been occurring on a new 24x7
Windows server blue screening daily, in spite of all the "fixes" that
have occurred to solve the problem (more hardware, patches, reload os,
etc, etc).

We'll soon be moving the application to an AIX server, but I'll have the
same questions on an HACMP cluster at that point :)

TIA
