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

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.

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.

TODO

• Get a PTP signed cert for chevy, so we don't warnings on https.
