Message:Virtual machine detects a loss in guest heartbeat

Hello Everyone,

I keep receiving "Message:Virtual machine detects a loss in guest heartbeat" which occurs during a Veeam backup job.  I understand this may be caused by process of using snapshots but is there a way to increase the timeout on the Host or Guest so that it wont be spamming out messages like this?

Thanks in advance.

Are you seeing this on a lot of VM's?  It could be that the machine actually needs more resources and the freeze/backup is actually causing performance degradation.  So, i would be careful about ignoring the alerts. You may also need to update or reinstall your vm tools

I see this on 4 different host machines all using the Veeam software to backup the data.  These "losses" appear to be a very short amount of time because I never see it disconnect from the VSphere application.  The messages I am receiving are via SNMP alerts from the host machine.  I am curious if there a way to increase the time on the host before it sends out an alert of a loss of heartbeat to the guest.

We actually use VEEAM witn SNMP traps as well and I noticed them in our environment, but we don't get email alerts on them so we mostly ignore them.

I was looking around for some type of time setting but have been unable to find anything so I am unsure if it is possible.  May want to open a support ticket and see if even possible.

There is a way in vmware HA to ignore them for certain intervals when doing VM monitoring, but that isn't really related.

Has anybody meanwhile found a way how to configure this heartbeat timeout?

I am experiencing the very same issue with repeated SNMP traps indicating first a loss, and then a regain of guest heartbeats after 30 sec. I don't want to disable those traps, as recommended here https://kb.vmware.com/s/article/57216?lang=en_US. But those traps are annoying and I assume that they would go away if I could increase this "alert threshold" by a few seconds.
