Virtual Machine OVC Memory Usage alarm appears incorrectly

[J-Philippe]

Hello I'm looking for some advices about tuning the OVC memory alarm to avoid monitoring to panic :-) May I create a folder in the vCenter, add the OVC and then disable on that folder the memory alarm ? Is it a good way to proceed or should / must I let the OVC "as is" at the root of the vCenter and let alarms come and go ? Thanks Jean-Philippe

Hi @J-Philippe 

I believe you may be referring to the following issue covered in this VMware KB

https://kb.vmware.com/s/article/2149787

I would not recommend making any changes to the OVC or folder structure.

Let me know if this is what you are referring to.

Thanks,

DeclanOR

Hello Declan, yes that's the point, sorry I've missed the VMware KB. Thanks for your quick feedback I'll let it by default. We will just skip the alarm from our monitoring. Best Regards, Jean-Philippe

Hi @J-Philippe 

No problem at all.

We see this quite often, and the best solution is the one outlined in that article. (If you want to get rid of the alarms)

Alternatively, live with the alarms knowing it's not actually a problem.

Thank you,

just increase the memory to 72GB

Sorry, increasing memory will not work for long. As mentioned in the VMware KB, it's a false alarm caused by the use of PCI passthrough devices by the OVC.

Dear all,

may I know whether we can reduce memory of OVC or not?

default setting is 108GB, but I want to reduce to 64GB because I am short of memeory resource.

Do not change the memory allocation for the OVC. It is normal for your production needs to grow and the best way to address that is to expand the federation with additional Simplivity systems.
