Good VM Monitoring tool

We have a vSphere 4.0 environment. We are having some disk I/O issues with a couple of VMs on an iSCSI array.  We believe that we know what the issue is and how to fix it. But before we implement the fix, we'd like to get a baseline of what the disk I/O is now and then what it is after the change. We originally determined the issue by running perfmon's on the VM, but would like some other utility that we could run that might be "better". And we'd like this to be one that would monitor other aspects of the virtual environment.

Free would be good, but I'm not opposed to paying for something either.

You might try Veeam Monitor 5 - I believe they have a free edition, and in any event they have a trial of the full version. http://www.veeam.com

Good Luck

Veeam's Reporting Tool should provide some help for you.

Free Tool: Subnet Calculator

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

One of a set of tools we're offering as a way of saying thank you for being a part of the community.

Are you using vCenter?  If not you should look at purchasing.  Other monitoring software such as Veeam Reporter or Quest vFoglight are also good 3rd party apps for monitoring.  Are you using free version or licensed version of ESXi?

I'll check out the Veeam stuff.  We are fully licensed with vCenter on vSphere 4.0. But vCenter doesn't seem to show disk I/O information, just space usage.  It does a pretty good job on things like CPU and memory, though.  We had looked at vFoglight and think it's an excellent program, but at least for my immediate need it's almost too complex with too many things to set and watch.  I even went through a tutorial with the company.  We might look at it for future use though.

Sure it does - select your server, click the performance tab, then pick disk from the dropdown - it will show read and write i/o rates for each datastore.

Switch to datastore view and you will get the read and write latency for each datastore. You can also select storage adapter and get the latency for each vmhba you have. And finally pick storage path and it will break out the latency per path to the storage

Forgot to say on performance tab you have to choose the advanced view...

Hi

Also I think Veeam Monitor is a good choice.

Also VM Turbo work as an Virtual Appliance in the VMware Infrastructure. For monitor only its a free tool. I am testing this Appliance, and until now it get give us lots of information about our VMware Infrastructure.

You can take a look and see if this can fit what you need.
