[monkeydelufy]

Hey!

Can you elaborate further on the problems you're facing?

Have you tried to implement monitoring with VMware templates?

hi kyus,

like my question i try to monitoring real usage memory by the esxi host not provisioning memory to all vm, can you help how to do that?
from my image shown above, that real usage memory my esxi host around 60GB how to achieve this result, because from zabbix vmware template showing only total provisioning memory to all vm not real usage.

From what I've read in the docs there isn't any items that display memory usage for each hypervisor in that template. Only for each VMware guest.

Maybe you could try to create a custom item that would get this metric from VMware. I never did it, so I don't know if it is possible...

Another option could be to look into aggregation in graphs or foreach functions in a calculated item. Again, I never needed something like this, so it will require some testing to see if it is possible at all.

Hi kyus,

thanks for your time to reply, i try create the item but still no luck already read documentation regarding vmware monitoring still no clue, can you pointing me to the right direction what item key for this.

I found some documentation that can probably help you:

Here's the VMware template documentation (including an explanation about custom items):

https://www.zabbix.com/integrations/vmware

Here's the item that you'll probably use:

https://www.zabbix.com/documentation/7.0/en/manual/vm_monitoring/vmware_keys#vmware.hv.perfcounter

Here's the documentation about how to setup this item:

https://www.zabbix.com/documentation/7.0/en/manual/appendix/items/perf_counters

Here's the documentation of the VMware API:

https://developer.broadcom.com/xapis/vsphere-web-services-api/latest/

I think that you can start from this point and see if you can make it work.
Good luck!

hi kyus,

already read the documentation still no luck i cannot find keys for my need, still don't know how to achieve my goal.

[kyus]

There is no "default" key for what you need... You'll have to create a custom one (probably using this vmware.hv.perfcounter item that I linked)

Sorry for the misunderstanding—never mind, ESXi doesn’t support the typical Zabbix Agent for Linux.

To monitor real memory usage, you’ll need to rely on the VMware API. Zabbix’s VMware Hypervisor template is designed for this purpose and can gather metrics directly from the ESXi host. It retrieves data like actual memory usage (mem.usage.average) and other performance metrics via the API.

i think you misunderstanding i use vmware hypervisor for monitoring my esxi host, my question is how monitor real memory usage esxi host used by all vm

[kyus]

This information that you want is provided by the VMware API. But there's no item to gather such metric in the template you're using...

Yes you can monitor it, but you'll have to look for a way to gather those metrics through the VMware API.

The links that i sent explain how you can do it using some vmware.* items...
