Too many events “Host hardware sensor state” after ESXi upgrade 6.5 to 6.7U3

This post was originally published on this site



We recently upgraded our vCenter and our ESXi hosts to 6.7 U3.


We noticed that the SEAT DB was filling up quite fast.

Last week stats:

Somehow we are getting a lot more events compared to pre-upgrade (6.5).


To avoid reaching 100% usage, I purged some of the biggest event tables in VCSA and I changed all statistics level to level 1 and changed retention to 30 days (default settings).


I investigated and found that our vCenter is logging plenty of “Host hardware sensor state” events:



These events are new and we didn’t have them pre-upgrade.


I found other people having the same issue:


ESXi 6.7U3 on Dell, syslog blowing up with hardware events? : vmware


ESXi 6.7 Update 3 (14320388) repeating Alarm ‘Host hardware sensor state’ – VMware Blogs – VMware Blogs


I created a ticket at VMware support. I’m waiting for an agent to contact me.


Meanwhile, does anyone else experience this?


Do you have a trick to stop these specific “Host hardware sensor state” events from being generated?
