We ran some test jobs on a newly P2V'ed VM yesterday but forgot to
monitor for the CPU , IO , RAM statistics : if I'm using VIC to connect
to vCenter, is there a way to churn out the CPU etc stats from yesterday
& if so , pls give me the step by step instructions (click by click).

How long is the performance data kept in the vCenter  / VIC ?

If can't churn out from VIC, how can I do it from vCenter (step by step
instructions as well ) , thanks

Summary data is kept for ever, if you have vCenter Server, it's recorded in the database.

if you do not have vCenter Server, it's only available fro 24 hours.


HOW TO:  Performance Monitor vSphere 4.x or 5.0

Actually, I think the stats are retained in the vCenter DB, but the vCenter DB defaults to data retention of 180days, unless that is solely just tasks & events?

vCenter should provide the info you need - just click on the VM > Performance tab > then select the appropriate option from the drop-down (CPU, Disk, Memory, Network, etc.). You can also click the 'Chart Options' link to select specific resource metrics and length of time (day, 7 days, 1 wk, etc.).

> drop-down (CPU, Disk, Memory, Network, etc.).
I suppose from the above, I select "Switch To: " & select from
the options from the Drop-down menu, right?  Does this chart
allow me to scroll back for up to 24 hrs as Hancoccka mentioned ?

that is correct.

information without vCenter Server, is just displayed in realtime, once the window has peformance window has lapsed the information is gone, and not viewable.
