[mrtg] Re: Thresholds and Alerts via Email ???

[Griner, Jeremy]

In my Unix threshhold script I check for the existence of a threshhold
parameter file which I create when a threshhold is reached.  If it exists
then I skip the routines to send a page/email.  Also, I added a line to my
crontab to remove all threshhold files every hour so I will receive a
reminder each hour but not get the annoying page every 5 minutes.  In my
threshhold ok script, I remove the particular file for that threshhold also.

threshhold.sh:
#!/bin/sh
Path=mrtg/thresh/tmp	#this is where I keep my tmp threshhold files
Parameter=$1
Thresh=$2
CurrVal=$3

if [ -r $Path/$Parameter ] ; then
        RCVRS=none
else

 #Variables to define for mail/paging aliases and command line executables
        RCVRS=your mail alias or your paging alias
        MAIL="mailx -s"  or your mail app command line
        MAIL_SUBJ="MRTG Threshhold Alert"
        PAGE=/usr/local/bin/send_alert    or your paging software's
executable

 #Define text to be sent
        echo_info()
        {
        echo "$Parameter $CurrVal % used"
        }

 #Mail/Page with the text defined above then create the tmp file with touch
so we can check to see if it exists next time
        echo_info | $MAIL "$MAIL_SUBJ" "$RCVRS"
        $PAGE $RCVRS "MRTG $Parameter Threshhold Alert.  $CurrVal % Used"
        touch $Path/$Parameter
fi

Crontab entry to remove the tmp files every hour at 1:02, 2:02, 3:02,
etc...:
