Monitoring missed disks

[renato.souza]

Hi guys,

I have a situation where I need to trigger the absense of a disk. For instance, if the number discovered disks by the LLD process is smaller than the previous number, I need to trigger that one disk is missing.

How can I do this?

Thank in advance!

I'm thinking to use {Template OS Windows:vfs.fs.size[{#FSNAME},total].nodata(300)}=1, what do you think?
