Monitoring VM Guest o/s without Scom agent

Post by mwinchester » Apr 29, 2010 10:48 am

Hi

We are led to believe that there is a level of monitoring of guest o/s provided without the necessity of having a scom agent installed therefore reducing the microsoft license costs.

Can somebody tell me exactly what monitoring is provided for mainly windows server based guests.

Thanks

Mark

Hi Mark,

Through VMware Tools driver, both nworks MP and SPI can monitor logical partitions free space (c:\ d:\ etc) and check presence of GuestOS heartbeat. This is quite basic monitoring of course.

If there is a need to monitor eventlog, do services probing, collect metrics and so on, then an agent is of course the only option.

You can reduce the number of systems with agents installed on them for RMS performance optimisation first thing, not speaking about licensing. If there's only "Core OS" MP installed in significant agent rollout, and your monitoring focused on performance first priority, metrics collected from within the guest would anyway be incorrect, as agent wouldn't be showing CPU Ready time, Memory Balloon driver inflation. This is what we call a "tunnel vision".

Cheers,
Kind regards,
Arseny
