Alert: Veeam VMware: vSphere Host Memory Overcommit

Veeam Logoby felyjos » Thu Aug 08, 2013 8:17 pm

Hello,

I am getting alerts in SCOM:
Alert: Veeam VMware: vSphere Host Memory Overcommit

Does Veeam Reporter 6.5 (Veeam One) has a report or dashboard to show this... I am seeing for VMs but not for ESX Hosts...

Thanks,
Dom

Hi Dom,

Which version of Veeam MP and SCOM do you have? If you have MP v6.0 and SCOM 2012 then the MP includes a Dashboard for this (Analysis or Top 10 dashboards for memory metrics)

If you have previous version of MP 5.7, and/or SCOM 2007, then you can still report on the memory metrics for VMs using the Performance History reports (Top Objects)

Cheers
Alec

Hi Alec,

I have a mixed :)
SCOM 2007 R2 CU6 ==> 6.1.72221.99
Veeam MP ==> 6.0.0.1421
I tried Reporting > Veeam VMware Perfromance History Reports > vSphere.Hosts.Memory Performance History
but no luck...
Group: MBESX3 all objects
All Counters
From yesterday to Today

Is it the VMHOST-memory\memory pressure (HOST.Collect.memroyPressure) graph?

Thanks,
Dom

Aha, that's OK, mix also works :D

As you have MP v6, you will have the additional Analysis details in the Alert description - that will give you the Top 5 VMs for memory allocation on that Host.

And you also have the MP Right-Sizing Reports.

I'd suggest run the Oversized VMs report against the VMs on that Host (you can add them individually to the report scope). That will tell you if you can safely reduce the memory allocation to any of those VMs.
And if you reduce the memory allocation overall for the host, then you will reduce the memory pressure. And you'll know that your environment is right-sized :D

Cheers

And yes - to answer your previous question, the 'memory overcommit' alert is based on the host memory pressure metric. This metric is memory overcommit expressed as a percentage (when you are overcommited, this metric is greater than 100%).
