Stressed memory on VM

[mcvosi]

I have a FT-enabled VM and vCenter Operations Manager is reporting a 6.0 percent memory stress.  Should I add more RAM for this VM?

While the VM is selected in the  navigation panel, select the Planning tab, from there select Views and  click on Stress in the Views Gallery.  You should see in the Undersized  chart what % memory your VM is undersized.  This will help you decide  how much additional vRAM is needed.

I  would also look at workload, specifically the overall workload for  memory and chart that out for the last 7 days to see if you have a  regular pattern of sustained high memory workload.  If it's a blip  caused by backups at 2am, for example, you may not want to increase the  memory.  On the other hand if the VM is showing undersized by 20% and  the high workload is during business hours then I would add vRAM for  sure.

How long has vC Ops been running in your environment?

It's been running for almost a week.  I re-sized the VM, adding an additional gig of vRAM, but it's still showing an alert with 25% memory stress.

You really would want to let vC Ops run for at least a couple of weeks before acting on anything.

OK, thx.
