Hi,
I'm monitoring our VMWare server infrastructure with SCOM 2012. I'm looking for a bit of clarification Re the metrics which SCOM produces to those that are provided by vCenter.
Basically this has stemmed from seeing some alerts such as Available megabytes of Memory monitor which has alerted due to SCOM reporting the agent has < 100MB available yet the vCentre memory reports show guest has well above the threshold available and therefore shouldnt have alerted. So when discussing with our server team who would rely on the vCenter metrics, its causing them to lose faith in any metrics/alerts which SCOM is gathering. - the various CPU/Memory performance graphs from SCOM are not consistent with the vCenter ones.
Can anyone advise if the SCOM metrics are (more) reliable than the native vCenter ones as indicators of health and provide the evidence for arguing the case either way.
Any help much appreciated - and Merry Christmas :-)
