Get-VIEvent takes way too long since update 7.0 Upd 3c

Hi,

Few days ago we upgrade two linked vCenters to vCenter 7.0 Upd 3c (from 7.0u2d), all seemed well and of course snapshot has been removed just before we discovered an issue. The issue is that since the update, the Get-VIEvent takes way too long. For example the following command:

Measure-Command{ $VIEvent = Get-VIEvent -maxsamples 100 -Start ($Date).AddDays(-1) }

vCenter A = 50 hosts / 800 VMs and the command takes 21 seconds

vCenter B = 80 hosts / 1400 VMs and the command takes 12 minutes. 

Any ideas what could be wrong?

Do you get the same (long) runtime when calling the API directly?

You could try the Get-VIEventPlus function from my Get the vMotion/svMotion history post.

Ran it like this:

Measure-Command{ $VIEvent = Get-VIEventPlus -Start ($Date).AddDays(-1) } 

Finished in about 5min

But it did give me some errors:

I suspect you hit the 300 seconds default timeout for web operations.
You can increase that via the Set-PowerCLIConfiguration cmdlet with the WebOperationTimeoutSeconds parameter.

Already discovered some other issues in this vCenter as well, not just powercli. Created a ticket with VMware Support.

 

Thanks for the help!

So in conclusion, it doesn't appear to be the Get-VIEvent cmdlet 😁
