Question about VMware Virtual Machine sensors

Votes:

0

I'm using VMware Virtual Machine sensors to monitor the virtual servers on our ESXi's. How can I monitor free disk space on my virtual servers using these sensors? The only channels I could find are for disk activity, none for free space.

Hello,

to see the free disk space inside a VM it's necessary to add the VM as a device and then add an according sensor (for example WMI Disk Space if it's a Windows VM), because the ESX(i) might not always know the file-format of the VM and therefor might not be able to even say anything about the usage.

best regards.

Hello,

Is it still the case now? Is there a way to monitor free disk space of VMs linked to the VCenter?

Best regards.

I'm very much afraid this is still the same. No changes here. If you need to monitor free disk space in a VM, it is necessary to add the VM as a device in PRTG and then monitor it from the "inside" with WMI, SSH, SNMP, according to the type of OS running on it.

So if you have like 200 VMs, you can use a device template to get all the sensors for each VMs, ut you have t ocreate all of them one by one by adding a device?

Using a device template is a very good idea. You can combine it with an Auto-Discovery on a list of IPs / hostnames. That would save you creating each device one by one manually.

I need to do the same thing in a multi-tenant setup. Do I need to add a probe inside every customers container to make this work?

No you don't need Remote Probes in each VM/Container. If they respond to normal SNMP/WMI/etc. queries from a Probe somewhere in the network, it will just work fine without Remote Probes inside each "machine".
