lvm: free disk space monitoring?

[Schwammkopf]

hi,

Is it possible monitoring lvm devices?

At the moment I only use disk monitoring on a server like this:
{Template_Linux:vfs.fs.size[/var,pfree].last(0)}<10

But its uncomfortable to create for every lvm device its own trigger.

For example, I have 4 mounted lvm devices:
/dev/mapper/vserver-aaa
10G 977M 9,1G 10% /var/lib/vservers/aaa
/dev/mapper/vserver-aaa-var
12G 1,1G 11G 10% /var/lib/vservers/aaa/var
/dev/mapper/vserver-bbb
4,0G 413M 3,6G 11% /var/lib/vservers/bbb
/dev/mapper/vserver-bbb-var
10G 479M 9,6G 5% /var/lib/vservers/bbb/var

how can I realize monitoring lvm devices from a server with only one trigger for all? With the trigger-condition 20% or less --> inform me.

Hello, thanks for reply.

I dont think that this is what I need because I dont need the total disk space of the lvm devices but rather a trigger which checks every lvm device separatly.

otherwise for example:
4 lvm devices, 3 of them use 60% and one 100%.
then I dont get any information that one device is totaly full.

Is the only way to make sure that no device gets full by checking every device with its own trigger?
