Hi Hallet,
my five metrics:
Harvest Duration
Smartstor Duration
Overall Capacity
Number of Historical Metrics
Number of Live Metrics
We use the following two, in addition, as output of EPAagent (df -k, vmstat):
EM CPU I/O wait Percentage
EM FileSystem available space.
and this one as output of EPAagent logreader:
Skew time over thresold (we have a recurring problem due to VMWare configuration)
We built alerts on these metrics and we feed with metrics data and alerts an APM Infrastructure Dashboard displayed in 55 inch monitors in FLS/SLS Rooms. We have this kind of dashboard for each APM production environment.
For skew time over threshold we added a email notification to FLS/SLS groups.
In my opinion this document has sufficient information (but the information is't never enough...)
