RE: {bb} mrtg and larrd problems

["Aaron Clasby" <aaron.clasby@cicadacorp.com>]

I am using bbmrtg.sh to get the stats for me.
I have uncommented one of the ports and I am not getting anything and
its been quite a while, much longer than a day. I can go and add routers
all day long and not have a problem. I don't know what it is with the
switches that is causing a problem.

Are you trying to do this with LARRD or bb-mrtg.[pl/sh] ?
Doing this with LARRD (IMHO) wouldn't be a good idea.

This is more of a regular mrtg configuration issue.
The ports are probably commented out because there might not 
be an individual speed setting via snmp displayed.  I don't 
know Dell switches, but just uncomment the lines for the ports 
you want to monitor and have a go at putting them into BB.

At least let it monitor for an hour or so to see if the data 
on each port is graphed individually.  Sometimes monitoring 
each port shows the same data or doesn't display the true 
amount of data traversing through the switch.  It could 
be you end up monitoring the backplane.

I am having a difficult time setting up new hosts in mrtg/larrd. My
goal
is to monitor each port on our Dell PowerConnects 48 port switches.

First, I setup the bbmrtg script with the following lines as an
example.

172.20.100.200_1 sw4_1 mrtg 80% 90% 10000000 Bits/s In Out

172.20.100.200_18 sw4_18 mrtg 80% 90% 10000000 Bits/s In Out
172.20.100.200_19 sw4_19 mrtg 80% 90% 10000000 Bits/s In Out
172.20.100.200_20 sw4_20 mrtg 80% 90% 10000000 Bits/s In Out
172.20.100.200_21 sw4_21 mrtg 80% 90% 10000000 Bits/s In Out
172.20.100.200_22 sw4_22 mrtg 80% 90% 10000000 Bits/s In Out
172.20.100.200_23 sw4_23 mrtg 80% 90% 10000000 Bits/s In Out
172.20.100.200_24 sw4_24 mrtg 80% 90% 10000000 Bits/s In Out

Then I ran the following to create the config portion.
/usr/bin/cfgmaker --ifref=descr --global 'WorkDir: /home/mrtg/html'
--global 'Options[_]: bits,growright' --output
/home/mrtg/cfg/mrtgtest.cfg c1cada@172.20.100.200 

I end up with the following result.

#Target[172.20.100.200_@]: 2:c1cada@172.20.100.200: 
#SetEnv[172.20.100.200_2]: MRTG_INT_IP="" MRTG_INT_DESCR=""

#   <TR><TD>Max Speed:</TD>  <TD>100.0 Mbits/s</TD></TR>
# </TABLE>

and then modify it by unremarking the needed lines.

### Interface 2 >> Descr: '' | Name: '' | Ip: '' | Eth: '' ###
### The following interface is commented out because:
### * --ifref=descr is not unique for this interface

 </TABLE>

I then placed the modified data into the mrtg.cfg file.

I thought it was weird that all of the lines in the config were
remarked
out, not sure if this is a standard thing or if I am possibly missing
something. Thought this may be closely related to the reason on why
mrtg
isnt working for me properly.
