I use SNMP to monitor all of my virtual machines and all of my host machines. What guest O/S's are you using? Is there any reason you can't use the SNMP agent that's included with the O/S? I use the Windows SNMP agent on my Windows VMs and net-snmp on my Linux VMs and everything works fine. The Windows SNMP agent supports drive space monitoring, as does net-snmp.
Since i just started rolling out SNMP for monitoring with Whats Up Gold, the first problem I have encountered is returning a value for disk space on VM Clients.
It is a windows 2003 Std server running VM Server 1.03 There is only one VM client on the box. I havent rebooted either the host or the client, because both are in production.
Unfortunately, switching monitoring systems at this time would be out of the question simply because of the amount of time and money already invested in Whats Up Gold.
I guess my real question is do I need special MIB's to monitor the VM client?
The host server SNMP monitor is working properly and shows that the drive space is ok.
I don't know. It may be the What's Up Gold uses different MIBs or different monitoring than standard SNMP - I don't know anything about that product. As far as VMware goes, there's nothing special required for monitoring either the host or guest systems. As I stated before, I use SNMP on both my host and guest systems - without any special setup - and it works fine. I use the built in SNMP agent on Windows guests and the net-snmp agent on Linux hosts and guests. Aside from configuring the correct communities and allowed hosts, I don't have to do anything special.
Well, I got snmp working on both the Win2K3 host and the win2k3 client, but even more strange things are happening.
With SNMP disabled on the host, the client will run normally.
About 1 minute after starting snmp on the host, the vm client seems to crash or "hose up" and then i have to stop VM Services on the host, and restart the client.
Are you using NAT or Host only networking or do your
hosts have Bridged connections?
By VM client do you mean the VMware Virtual Machines
or the SNMP agent running in the VM's?
Bridged connections
i am referring to the Virtual Machine, when I say VM client.
This sounds like your SNMP agent is doing something bad, or you have a problem with something on your host. Starting a simple service like SNMP should not cause everything else on the system to crash, and certainly shouldn't affect VMware's ability to run.
