vCenter Server Health Alarm

[BCAdmin]

We have vsphere v 6.0. I am logged on to the Web Client and it is showing a critical alarm:  VMware vCenter server Health Alarm. In the details, it shows the following:

I googled the error, but I the result were very broad and generic. They did not seem to relate to my issue. I am unable to find the 'workflow manager' service. Can you tell me if this is benign alert?  Can you tell me where I might find a resolution for this alert?

Thank you.

Since we are not using Orchestrator, is there a way to disable this specific alert?

Hi,

how many vRAM did You assign for this vCSA? How big is Your environment? How many hosts and VMs running and registered?

[BCAdmin]

16 gigs

12 hosts

100 VMs

[vmrale]

You could do two things. First one is to increase the size of vRAM assigned to vCSA to 17-18 GB, but if You have enough resources and it is going to demand a reboot of vCSA. Check if the problem is solved now.

The other choise is to increase a Java heap size for this vmware-vpx-workflow service. Follow this procedure:

VMware Knowledge Base

cloudvm-ram-size -l - shows memory allocation in MB for particular service.

cloudvm-ram-size -J service_name - displays the heap size

cloudvm-ram-size -C heap_size service_name - changes the heap size.

In this scenario reboot is not required.

We are using less than 25% of vRam, so I will not increase the size at this time. I will investigate option #2 and follow up shortly.

Thank you.

[BCAdmin]

Before moving forward with option #2, I decided to power cycle the vcenter server. The alert is gone now.

I appreciate your assistance.

My service request is complete, but I did not completely follow your instructions.  Is it proper to mark the subject 'answered' so that you earn credits for your time, or is it only marked 'answered' when the instructions provided resolve the issue?

[vmrale]

I'm glad You resolved the issue. I try to help people avoiding to recommend a restart in the first place, but from my experience restarting vCSA usualy helps to properly start all services that are dependent from each other.

If You thing my answers were helpful or correct, just mark them as 'helpful' or 'correct answer' please.

Regards
