[Devmon] How to if_* graph from Devmon to Hobbit

[xbgmsharp <xbg...@gm...>]

In hobbit

etc/hobbitlaunch.cfg

# "rrdstatus" updates RRD files with information that arrives as
"status" messages.
# If you want RRD graphs of your monitoring data, then you want to run this.

[rrdstatus]
           ENVFILE /data/hobbit/server/etc/hobbitserver.cfg
           NEEDS hobbitd
           CMD hobbitd_channel --channel=3Dstatus \
                   --log=3D$BBSERVERLOGS/rrd-status.log hobbitd_rrd \
                   --rrddir=3D$BBVAR/rrd \
                   --extra-script=3D$BBHOME/ext/extra-rrd.pl  \
                   --extra-tests=3Dif_load,if_err,if_col

This defines the script which is use to generated rrd file.

extra-rrd.pl is a script of mine and it generated rrd data in a file.

And here is the body:

#!/usr/bin/perl

# Input parameters: Hostname, testname (column), and messagefile
#$HOSTNAME=3D$ARGV[0]; ;
$TESTNAME=3D$ARGV[1]; ;
$FNAME=3D$ARGV[2]; ;

# Read the entire files
open (FILEHANDLE,$FNAME) || die ("cant read file\n");
@input =3D <FILEHANDLE>;
close (FILEHANDLE);

if ( $TESTNAME eq "if_load" || $TESTNAME eq "if_err" || $TESTNAME eq
"if_col") {

           # Analyze the message we got
           foreach $line (@input) {
           # Debug
           system qq# echo "$line" >> /tmp/if_log #
                   if ($line =3D~ /(^[A-Z].*) (\d+):(\d+)$/ ) {

                           # The RRD dataset definitions
                           print "DS:in:DERIVE:600:0:U\n";
                           print "DS:out:DERIVE:600:0:U\n";

                           # The filename
                           print "$TESTNAME_$1.rrd\n";

                           # The data
                           print "$2:$3\n";
                   }
           }

}

exit 0


Hope this help.
