Unknown hypervisor uuid.

[strelokr]

Hi there.
I have zabbix 4.4 and esxi 6.7 connected to vCenter. Two other one can discover and send CPU/ ram load informain.
But last one on brand new Xeon Gold proccers send error. Unknown hypervisor uuid.
I was try official template
vmware.hv.vm.num[{$URL},{HOST.HOST}]" became not supported: Unknown hypervisor uuid.
and your one with the same error message
vmware.hv.cpu.usage[{$URL},{$UUID}]" became not supported: Unknown hypervisor uuid.

vCenter reviced from host all information.
Do you have any suggest?
big thanks for any advice.

I also had issues because I tried to use the esxcli system uuid get command, which gave me a UUID but the wrong one, you need to follow the method stated in the read me. If you do this it works flawlessly.

I am getting the UUID as described in the official guide. it didn't help me

Some things are not working exactly as they should like the data store stuff but I think that is because it wasn't to be a vcentre host, I am only using free esxi.

Have you tried to run this from the shell? esxcfg-info -u |awk '{print tolower($0)}'

Hi,

Have you found a solution to this problem?
I'm experiencing the exact same issue. I tried using the UUID obtained from the following commands:

esxcli system uuid get
vim-cmd hostsvc/hostsummary | grep -i uuid
Both commands return different UUIDs, but neither of them works.

Any advice would be appreciated!

Hi,

I won't be of much help as I don't have any running ESXi for a few years (and the end of free license has doomed ESXi for me)
However I remember having seen that uuid are case sensitive so you might try to put your uuid in lower case

Hi,

I’ve found the solution to the problem!

For free ESXi, the correct UUID can be retrieved using the command:
vim-cmd hostsvc/hostsummary | grep -i uuid

In my case, the issue was related to permissions!
I created a Zabbix user and assigned it the Administrator role on ESXi. However, when I logged into ESXi via the web interface using this user, I realized it had no actual permissions. I had to reassign the Administrator role to the user once again!

I’m not sure if this is a bug or something else, but even though it was marked as an Administrator, it wasn’t in practice.

I tested this solution on Zabbix 7.0.6 with the free version of ESXi (ESXi-8.0U3b-24280767-standard), and everything is working correctly now.

I think this issue can be closed. However, I suggest adding a note to the README file stating that after creating a dedicated monitoring user in ESXi, it’s essential to log in with that user and verify its permissions. Make sure the user can see all VMs, datastores, and, of course, the host itself.
