[xymon] ESX 4.1

[Storer, Raymond]

Jason, I would say yes; you can just use VMA and Xymon. In fact, after looking at the VMX screen shots I do not believe it provides enough information about the ESX performance. I did not see a CPUReady% counter for each VM, e.g. I'm sure with a couple hours of coding you could put something together using VMA and the Xymon client. If you didn't know, PowerShell and the VMware PowerCli work well to get statistical information from your VMware environment too.

Good luck!

Ray

Is it safe to assume that if I do not want to monitor the usage of each VM against the ESX server, all I need would be the VMA and the Xymon client from the link below and I can get at least an idea of the resources being used on the ESX server itself, or do I really need to have VMX?

I really don't like the idea of purchasing a license from an unknown guy for VMX. Seems really sketchy to me.

As Vernon wrote to the list in reply to your post installing a xymon-/hobbit-client on the ESX-host is not sufficient for monitoring the ESX. The reason for this is
a) the service-console is just a VM by itself, so there is no way to monitor the cpu- and memory-consumption of the "bare-metal"
b) the service-console will not be available in post v4.1 ESX-versions (at least that's announced by VMware)

Personally I havn't looked into SNMP because I had several reports by people running small to mid-sized ESX installations that it's both unreliable and reporting incorrect values.

"Vmware-Monitor for Xmyon (VMX)" takes the offical approach recommended by VMware (and is thus _fully_ supported and not in conflict with support-contracts, ...): the virtual management assistant vMA (a pre-built virtual machine with management-tools available from VMware):
        http://www.vmware.com/go/vma4
collects the data. Data-processing is done by a small daemon that generates the status-messages for Xymon.
Super-short outline how to get your ESX-monitoring up and running with VMX:
1. fetch the vMA from VMware from above url and install it.
2. install a xymon-client on the vMA, rpm available from
        http://staff.telkomsa.net/packages/rhel5/xymon/x86_64/
3. install VMX on vMA (client-extension script) and on the xymon-server (for data-processing and graphing)

In particular you do not have to install anything on the ESX-hosts.

For more details I've attached the VMX-documentation for your convenience.

All the best,

        Thomas
