Hi Group,

I am having a bit of a time understanding a NAGIOS alert that was setup be my 
predecessor.
I will show the alert that is on disc availability, and then below that I show 
the NAGIOS display
 of the alert conditions of dic conditions and lastly I show the actual values 
of the disc "df" command
from the Server itself. 

My question is this.....what is the service complaining about? There appears 
tobe plenty of disk space based on the email. The actual "df" itself seems
to be that there is space issues looking at bits but the availabile percentage 
seems high.

Thanks for your help in advance.
