[Devmon] DEVMON questions

From: Jeffrey P. <jw...@gm...> - 2008-06-18 16:23:28

Hello,

        I have been using DevMon for a while now to monitor my Cisco
routers under Hobbit.  I guess I'm being dense, but there are a few
things I can't figure out:

                1. If you have multiple routers of the same type that
you already have templates for, how do you differentiate them if they
require different monitoring parameters (exclusions, etc.)?

                2. How do I create new templates for routers that I
don't have templates for?  I know there are instructions, but it's not
clear to me how to create them so it knows that when I start
monitoring a new
                    type (Cisco 12000 series for example), how does
DevMon know that when the device is queried, that this device is
indeed a 12000 Cisco?  Where is that information kept in the template?

Thanks in advance,

Jeff

To answer your questions:

1.  Let's say we are talking about a 6509 and the template is cisco-6509.
What I do is copy the cisco-6509 to cisco-6509a.  I then modify the specs
file in the template and put a bogus "sysdesc" and modify the device to
match 6509a.  The issue with doing this way is that you have to add an entry
in the bb-hosts file for that hosts that forces it to use the cisco-6509a
template.

2.  The template instructions seem to be fairly straight forward to me.  But
you create yourself a folder with the model-device.  So for your cisco 12000
series you could create a folder called cisco-12k.  Now you need to create a
specs file for your template, this is what Devmon uses to know what type of
device your host is.  Your specs file would maybe look like this:

vendor  : cisco
model   : 12k
snmpver : 2
sysdesc : c6sup|s72033_rp|s222_rp

The sysdesc field is probably going to be a little different.  To find out
what yours would be do.

Snmpwalk -v 2c -c <community string> device-name sysdesc

Here is what my output shows me:

SNMPv2-MIB::sysDescr.0 = STRING: Cisco Internetwork Operating System
Software
IOS (tm) s72033_rp Software (s72033_rp-IPSERVICESK9_WAN-M), Version
12.2(18)SXF7, RELEASE SOFTWARE (fc1)
Technical Support: http://www.cisco.com/techsupport
Copyright (c) 1986-2006 by cisco Systems, Inc.

Once you see the output you can pick one or multiple entries separated by a
pipe symbol that show up in your output.
Now within your templates folder you will create a folder for each test that
you want to monitor.  Examples would be cpu, if_load, memory.....etc.  Now
each of the test folders require 5 different files:

exceptions
message
oids
thresholds
transforms

I think from this point you should be able to read the documentation and use
the other templates as examples of what you need.

At present, I do it via the DEVMON tag in the bb-hosts file

Start off with cp -a $similar_template $new_template

Have a MIB browser (or the MIB) and snmpwalk output on one screen ...

regex match on the Sysdescr OID to the sysdesc value in the specs file.

and read RTFM :) for create the template

Here all MIBS :
http://www.oidview.com/mibs/detail.html

And for explore your equipment MIB use Mib Browser Ireasonning and load your
equipment mib:
http://www.ireasoning.com/



If you join devmon with /etc/init.d/hobbit-server here's how do :


---------------------------------------------------------------------------
#!/bin/bash

USER_HOBBIT="hobbit"
PROG_PATH=`echo ~hobbit`

function EyeCandy() {
    sleep 0.5; echo -n ".";sleep 0.5; echo -n ".";sleep 0.5; echo -n ". : ";
}

function StartDevMon() {
    echo -n "Demarrage de Hobbit Server SNMP support : Devmon"
    EyeCandy
    su ${USER_HOBBIT} -c "${PROG_PATH}/application/server/ext/devmon/devmon"
    eval "CODERETOUR=$?"
}

function StopDevMon() {
    echo -n "Arret de Hobbit Server SNMP support : Devmon"
    EyeCandy
    killall -q /usr/bin/perl
    killall -q -s 9 devmon
    eval "CODERETOUR=$?"
}


case "$1" in
  start)
        echo -n "Demarrage de Hobbit Server"
        EyeCandy
        su ${USER_HOBBIT} -c "${PROG_PATH}/application/server/bin/hobbit.sh
start"

        StartDevMon
        [ "${CODERETOUR}" = 0 ] && echo -e "\t \t \t[OK]";
        ;;
  stop)
        echo -n "Arret de Hobbit Server"
        EyeCandy
        su ${USER_HOBBIT} -c "${PROG_PATH}/application/server/bin/hobbit.sh
stop"

        StopDevMon
        [ "${CODERETOUR}" = 0 ] && echo -e "\t \t \t [OK]";
        ;;

  restart)
        echo -n "Demarrage de Hobbit Server"
        su ${USER_HOBBIT} -c "${PROG_PATH}/application/server/bin/hobbit.sh
restart"
        [ "$?" = 0 ] && echo -e "\t \t \t [OK]";

        StopDevMon
        [ "${CODERETOUR}" = 0 ] && echo -e "\t \t \t[OK]";

        StartDevMon
        [ "${CODERETOUR}" = 0 ] && echo -e "\t \t \t [OK]";
        ;;

  status)
        su ${USER_HOBBIT} -c "${PROG_PATH}/application/server/bin/hobbit.sh
status"
        ;;

  *)
        echo "Usage: $NAME {start|stop|restart|status}" >&2
        exit 3
        ;;
esac
--------------------------------------------------------------------------------------




Good luck ;)

I personally use http://www.mibdepot.com/ , but will try snmpb  
(http://sourceforge.net/projects/snmpb) next.

Why? IMHO it's better to have a separate init script, such as the one supplied 
in extras/

Hello,

         Thanks to all who replied.  After I found the "devmon.html"
file for Hobbit in the DevMon archive, it all became clear.  Like I
said I was being dense :-).
I think I'm on my way now.

Thanks Again,

Jeff

[Devmon] Severe inaccuracy in devmon/hobbit rrd graphs

From: Kauffman, T. <Kau...@ni...> - 2008-06-26 14:24:00

I'm still fighting brocade switch issues.

First of all, the data gathering looks good, except that I cannot get the chart to show the physical port number (the box is labeled from 0 to 31; the snmp index is 1 thru 32; every time I try to do math on the index to get a port number devmon shuts down IF I report the calculated value anywhere on the table line)

But -

I see that port 3 shows an average of 3.67 words outbound and 11.6 words inbound. I run the math transforms and show the results in the table, and the calculated Byte count and bit count match. And the graph result from graphing the word values shows 6.14 M words in (average) and 6.14 M words outbound (average).

I was originally calling the values "if_load" and graphing the byte counts, to match the cisco templates. Every port was showing an average of 350 Mb/second in and out.

If I dump the rrd from graphing the word count, I see values that match the graphs.

Where is this getting so massively inflated? MRTG seems to work properly.

TIA

Tom
