Receive Notificaion for state changes of VMs on a node

[Michael Friedrich]

Hi everyone,

I am trying to find out how I could get a notification for state changes of a certain subset oft he VMs on a node in proxmox.
I have found two possible starting points:

* the log files (only logging afters tasks are completed)
* polling qm list for states running/stopped

Both possibilities unfurtunately do not fit my requirements. I would also need to find out if a VM is shutting down or starting up. I imagine there could be an event somewhere which I can use. The task viewer in the web-gui has the kind of information I need.
Can you point me in the right direction, if there is a way to get that kind of information, preferably without polling.

Best Regards,
Michael Friedrich

if you just want to know about the tasks executed, you can monitor /var/log/pve/tasks/index (on each node). but note that the guest state can change without a task (e.g., when powering off inside the guest). if you want to monitor the actual state, you will have to poll - either using PVE API calls, or by setting up a monitoring solution for the guests (like icinga/nagios, ...)
