Subject : [VMware vCenter - Alarm Health status changed alarm] com.vmware.vim.sms status changed from yellow to green
Stateless event alarm
([Event alarm expression: Status change])
com.vmware.vim.sms status changed from yellow to green
More specifically, I got about 20 of these..switching from green to yellow, yellow to green, and back and forth and back and forth.
What to do?
a bit of digging…
And I found this thread on Communities.Vmware.Com
I just got off the phone with vmware and they confirmed that this is fixed in 4.1u1. Below are the details from the Release Notes for 4.1u1:
Storage Monitoring Service synchronizations are erroneously sent as health status changed alarms
Storage Monitoring Service synchronizes its data every 30 minutes. When a synchronization occurs, the health status of Storage Monitoring Service changes to yellow. This synchronization operation is reported as a warning, which is not the intended behavior. These false warnings are delivered using the action that is set for the health status changed alarm. Therefore, the alarm can cause commands to run, or cause warnings to be sent as notification emails or SNMP notification traps.
This issue is resolved in this release. Warnings are no longer sent for this synchronization operation.
First, it’s a bug, fixed in esx 4.1 update 1. My clusters are not on esx 4.1 update 1. Considering I am fairly new to ESX and vmware, I figure it may take a bit of time before I figure out how to update (including researching implications, possible downtimes, etc.etc.).
In the meantime, thankfully there is a workaround
Please try configure “Health status changed alarm” from “UNSET” to “ALERT” or others.
And so far so good…
