  • 1.  vSphere UI Health Alarm

    Posted Oct 19, 2021 04:14 PM

    I'm trying to track down and fix what is causing these alert emails. Every time I log into the vCenter Appliance Management the health status shows as being green. Getting these alerts at random, sometimes every 3 to 4 hours.

    Alarm Definition:

    ([Event alarm expression: Status change; Status = Yellow] OR [Event alarm expression: Status change; Status = Yellow] OR [Event alarm expression: Status change; Status = Red] OR [Event alarm expression: Status change; Status = Green])

    Event details:

     vsphere-ui status changed from yellow to green

    You can find this alarm definition in Vcenter>Configure>Alarmdefinition

    In the alarm configuration, you should turn off email notifications on alarm rule 1 which triggers the notification when the status changes from yellow to green if you consider it´s not critical to receive this mail. If you check the other rules, there is a rule that triggers a notificatión when the status changes from red to green that from my point of view is a critical one.

    If you're looking to fix this problem so that you don't turn off any notifications, you have to increase RAM memory on your Vsphere host, in my case Vsphere is located on a virtual machine, so what I do is turn off correctly my Vsphere from the CLI, then add more RAM, the allocated RAM depends on the number of virtual machines running on your host. Check this article https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vcenter.install.doc/GUID-88571D8A-46E1-464D-A349-4DC43DCAF320.html

    Hello,

    i have the same Problem but my Vcenter Appliance already has 24GB RAM and 8 vCPU for approx. 200 VMs and 10 Hosts.
    So way above what is required.
    Anything else i can check to get rid of this warning?
