When using a cool router software like OpenWRT it is a good idea to monitor the network usage. This article describe howto get SNMP on your OpenWRT based router.
1. Install
The easiest way is to use the webgui, http://<your router ip>
- Log in as root/-<your password>
- Click on Adminstrator to enable the Advnced menues
- System->Software
- Click on "Update Package List" (this require Internet access).
- Install snmpd-static
2. Configure
Log in to the La Fonera using ssh:
peter@peter-laptop:~$ ssh -l root 192.168.0.159
root@192.168.0.159's password:
BusyBox v1.11.2 (2009-12-02 11:25:47 UTC) built-in shell (ash)
Enter 'help' for a list of built-in commands.

* 10 oz Vodka Shake well with ice and strain
* 10 oz Triple sec mixture into 10 shot glasses.
* 10 oz lime juice Salute!
---------------------------------------------------
root@fon:~#
Start snmpd
root@fon:~# /etc/init.d/snmpd start
Make it start when rebooted:
root@fon:~# /etc/init.d/snmpd enable
If you want to change your SNMP configuration the configuration is located in:
/etc/config/snmpd.conf
3. Monitor
Now you can get the SNMP data and use your favorite Monitor tool, i.e. Nagios or op5 Monitor.
Below a screenshoot from op5 Monitor:

hi,
good question from joe. i’m wondering what might be the difference between snmpd and mini-snmpd. i could not find any explanation.
i think, on openwrt i will only need an snmp agent (client).

My guess:
snmp-static, statically linked
mini-snmp, another implemenetation of snmp that hopefully has a smaller footprint.
Look into the projects homepages and figure out, or give me your Ipad and I will find it for you.
