FMC virtual appliance - CPU Usage - test fails since update to 6.6.1

[plwalsh]

Hi,

We updated our FMC virtual appliance from 6.4.0.9 to 6.6.1. It has the required 32GB RAM and 4 vCPU. Since the update the  CPU Usage health test in FMC Health Monitor reports as 'Test Failed'.

Has anyone encountered this issue?

Generally FMC virtual bit odd some time, i was not got the right results, compare to appliance cisco build one. since FMC required good CPU to process the Logs

Virtual CPUs

8 (minimum required) / 4

Thank you for that information BB. I will get 8x vCPUs for the FMC virtual appliance and see if the CPU Usage check will run.

Sure and keep us posted any assitance required further.

I assigned 8x vCPU and the health monitor CPU Usage check now runs correctly. The System Load widget on the FMC 6.6 Dashboard also works now - it did not work with 4x vCPUs.

I have had a lot of 'Drain event' alerts from my Firepower 2140 FTD device since I updated FMC from 6.2.3 to 6.4. Now that I have 6.6 and the correct resources it will be interesting to see the frequency of 'Drain events'.

Thanks again BB
