Trigger set for unmounted or removed file systems Notification

[ErenYener]

Hi,
I can find file systems using low level discovery and I can monitor these file systems.
but I need to configure a trigger that includes changes in number of the filesystems. For example:
Assume, discovery found filesystems named c: and d: OR / and /disk1. If any of those discovered filesystem removed, unmounted or added to the system. So, I need to know how to create the trigger that I mentioned above.

I don't think there is anything that can do this out of box. We only do this for UNIX, though I would imagine it would be easy enough to do via powershell as well.

We have a 3 part script we run on our UNIX hosts via cron which sends data into trapper items in zabbix. Below is the script which you can feel free to use, if you have any questions about the setup let me know.

Also just to note, we are planning on putting in a kill command in case the script hangs, just haven't had time to get that done.

parts
1. Checks that the filesystems can be written to
2. Checks that the file systems can
3. Starts the zabbix agent if it's not running

Zabbix Item Keys.
filesystem.ro.check
filesystem.mount.check

The Zabbix Triggers we use
if X > 0 trigger for key 1 and 2
If the host hasn't sent data for these items in 30 minutes
