Status
chevy is running Cacti, and monitoring all of the deployed metrixes and ciscos. The graphs are available at http://chevy.personaltelco.net/cacti/graph_view.php
Management interface at (self-signed cert, CN=baker.personaltelco.net needs to be updated to PTP-signed, CN=chevy.personaltelco.net) https://chevy.personaltelco.net/cacti/
Set up
Metrix
To set up a metrix box for monitoring:
metrix# remountrw metrix# apt-get install snmpd ash metrix# vi /etc/default/snmpd # set TRAPDRUN=no metrix# cd /var/lib metrix# cp -a snmp/ /ro/var/lib metrix# mv snmp/ /rw/var/lib metrix# ln -s /rw/var/lib/snmp/ . // Get snmpd and assoc_count from another metrix naya$ scp snmpd.conf root@metrix-ed.mississippi:/etc/snmp naya$ scp assoc_count root@metrix-ed.mississippi:/usr/local/bin metrix# /etc/init.d/snmpd restart metrix# remountro
- Add the device to Cacti with the Metrix Box template.
- Create the Associated Stations, ath0, ath1...athN graphs.
- Add the device to the main graph tree.
- Add the Assoc. STAs graph to the Assoc STAs page.
WGTs
The WGTs are using the ipkg repository
http://www.personaltelco.net/~russell/kamikaze/r3291/packages/
and have the snmpd package (with its dependencies) installed. They use the same snmpd.conf and assoc_count script as the metrixes, so they look pretty much the same to cacti.
Diagnostics
/usr/local/bin/assoc_count is a homebrew script. It reports the number of associations on ath0. It only works with madwifi-ng. snmpd.conf has the line
exec assoc_count /usr/local/bin/assoc_count
to enable it. This exports the association count on OID 1.3.6.1.4.1.2021.8.1.101.1. Other than that, everything is standard net-snmp exports. The assoc_count script, is quite simple, it looks like:
echo $((`wc -l < /proc/net/madwifi/ath0/associated_sta`/3))
TODO
- Get a PTP signed cert for chevy, so we don't warnings on https.
