Home Exim Debian JS Usage Mrtg tuntap pampop freestuff windows LCA
Update: Apparently the M1122 does support (slightly broken?) SNMP, at least in some revisions. It could pay to investigate this before following the instructions below.
The Nokia M1122 does not currently support SNMP, so getting it working with MRTG is a little more difficult. Here's how I did it:
I use Debian GNU/Linux, so I first installed the MRTG and expect packages. Expect is used to telnet on to the router and gather the data needed for MRTG.
Next I coded up a simple expect script, this is the first time I have used expect, so I just copied from an example.
#!/usr/bin/expect5.31 -- exp_version -exit 5.0 set timeout 60 spawn telnet 192.168.1.254 expect "login-id:" send "user\r" expect "password:" send "user\r" expect "M1122>" send "sh atm\r" expect "M1122>" send "sh st\r" expect "M1122>" send "lo\r" close
I saved this as /usr/local/bin/getm1122-raw, because
another script does some more massaging before sending it to MRTG.
Note that you may need to change the first line depending on your
version and location of expect.
When this run it should produce the following output:
spawn telnet 192.168.1.254
Trying 192.168.1.254...
Connected to 192.168.1.254.

Next I wrote a bit of awk to massage the output into the format required by MRTG:
#!/bin/sh
/usr/local/bin/getm1122-raw |
awk '/payload/{print $3}/uptime/{print $2}/short-desc/{print $2}'|
awk -vRS="\n\n" '{printf("%s\n%s\n%s\n%s\n",$2,$1,$6,$5)}'
I saved this as /usr/local/bin/getm1122, and the output looks like:
567705125 32870330 03/15:46:18 M1122
Now I filled in a section in the mtrg.cfg file as follows:
Title[m1122]: JetStream DSL PageTop[m1122]: <h1>Jetstream DSL via Nokia M1122</h1> Target[m1122]: `/usr/local/bin/getm1122` MaxBytes[m1122]: 1000000
Now everything was going - the debian package has a cron fragment that runs MRTG every 5 minutes, and puts the results in /var/www/mtrg/
I'd welcome feedback, corrections etc. to alex at king dot net dot nz
