Monitoring "apt update" on discovered VM (VMWARE)

[eglyn]

Hi all ,

I monitor all VM from my Vsphere cluster with zabbix and the integrated system to discover and monitor vmware.

It works great, but i would like to check if apt updates are available on VM guests running Linux (Debian).

There is a template wich works with standard monitoring (here --> https://iceburn.medium.com/monitor-r...x-e2de867d566a)

But, I cannot use this template because I can't assignate a template to a discovered VM, and there is no agent running on this VM :/

So, how can I do ? Do i need to duplicate all VM in Zabbix to add agent and monitor apt ?

thx !

If you want to get "inside" the host, then you need an agent. Or somekind of script based (ssh) thingie...

I use the following code to monitor apt updates:

#!/bin/bash
updateVarNum=`/usr/lib/update-notifier/apt-check --human-readable` > /dev/null
echo `expr "$updateVarNum" : '\([0-9]*\)'`

Then I create an ssh agent item to run the script.
