[hobbit] Hobbit Devmon question / help needed

Tom, 

the is no RRD inferface information in your html file. Only the definiton of the RRD file, but no actual information. 
So no information will be send to the rrd file bij the extra-rrd.script. 

You have to look at the devmon site for why there is no information. 

Regards, 

Bert Klomp

Thank you for the information but it still did not give me the RRD
detail.

The following code produces rrd files for me (straight copy and paste):

#!/usr/bin/perl

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

#Read the entire files
open(FILEHANDLE,$FNAME)||die("can't read file\n"); @input=<FILEHANDLE>;
close(FILEHANDLE);


if ( $TESTNAME eq "if_load") {

           # Analyze the message we got
           #open(OUT, ">", $filename);
           foreach $line (@input) {
                   if ($line =~ /(^[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 "if_load_$1.rrd\n";

                           # The data
                           print "$2:$3\n";
                   }
           }
        #close (OUT);
}

I've been looking at your message file but can't find anything strange
in it. 
What I did see was that there was no interface informatie in de RRD part
of your output.  
The RRD file of my output file looks like <!--DEVMON RRD: if_load 0 0
DS:ds0:COUNTER:600:0:U DS:ds1:COUNTER:600:0:U
Gi1_1 3631408838:1068715647 

Did you correctly identify the ifInOctets and ifOutOctets ? 

Regards,
Bert Klomp

I downloaded Devmon and have it running just fine.

However, I am having a problem with getting the stats from a Devmon
if_load status into rrd. The rrd's never get created. I did do the other
parts and since I am creating a tmp file from the extra-rrd.pl, that
would indicate that the code is executing !


Here is where I believe the problem is.

>From the extra-rrd.pl the code is as follows:

Code start ------------
#!/usr/bin/perl

# Input parameters: Hostname, testname (column), and messagefile
#$HOSTNAME=$ARGV[0]; ;
$TESTNAME=$ARGV[1]; ;
$FNAME=$ARGV[2]; ;
$filename="/tmp/if_log";

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

if ( $TESTNAME eq "if_load") {

           # Analyze the message we got
           open(OUT, ">", $filename);
           print OUT "This is the stuff\n at input";
           foreach $line (@input) {
                   if ($line =~ /(^[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 "if_load_$1.rrd\n";

                           # The data
                           print "$2:$3\n";
                   }
           }
        close (OUT);
}
Code stop -----------------------

I added some code to create and show what is in the if_load stat in the
/tmp/if_log file for debugging.

The /tmp/if_log file I see is:

bash-3.00$ cat /tmp/if_log

Here is a copy of the message file from
devmon/templates/cisco-7206/if_load


The message file for the device (7206) shows:

<b>Interface error rates:</b>
Input load:  yellow={ifInLoad.thresh:yellow}%,
red={ifInLoad.thresh:red}%
Output load: yellow={ifOutLoad.thresh:yellow}%,

({ifInLoad}%){ifInLoa
d.errors}|{ifOutLoad.color}{ifOutSpeed} ({ifOutLoad}%){ifOutLoad.errors}



I suspect the message file is wrong? But I have only started this on
Friday, so I figured the experts could point me to the right direction.
