Re: more user friendly filesystem space messages and checks

[Weedy]

I have 5.10 installed and I still get this.
I would like to receive the remaining free space in GiB or MiB if low enough.

  check filesystem home with path /dev/md2
    if space usage gt 5035 GB for 5 times within 15 cycles then alert
    if space usage gt 5039 GB then alert

Resource limit matched Service home

        Date:        Tue, 03 Feb 2015 18:46:44
        Action:      alert
        Description: space usage 1321079524 blocks matches resource
limit [space usage>1320941372 blocks]
