| * Set up SNMPd on all the metrixes. |
There ought to be some sort of monitoring for the current/past state of the network. Currently this page is a log of BenjaminJencks attempts to set this up. Currently we have http://buick.personaltelco.net/cacti/graph_view.php
Vision
Something, probably Cacti, monitoring all the APs for
- Number of associated stations (done with assoc_count script)
- Link throughput (built into snmpd, unless bridges cause weirdness (I don't see why they would))
- Link status? This might be derived from throughput
So Far
- mississippi has snmp tools installed
All currently deployed metrixes have snmpd installed, as well as /usr/local/bin/assoc_count, which prints the number of associated stations.
snmpd is configured to use assoc_count for OID 1.3.6.1.4.1.2021.8.1.101.1, otherwise known as UCD-SNMP-MIB::extOutput.1.
This means you can count stations with snmpget -c public -v 1 <<Host>> 1.3.6.1.4.1.2021.8.1.101.1
- Installed IEEE802dot11-MIB on mississippi. use -m IEEE802dot11-MIB option on snmp commands when you need to.
- Installed Cacti.
- Made host template "Metrix box" that includes # of STAs graph.
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 mississippi$ scp snmpd.conf root@metrix-ed.mississippi:/etc/snmp mississippi$ scp assoc_count root@metrix-ed.mississippi:/usr/local/bin metrix# /etc/init.d/snmpd restart metrix# remountro
Next Steps
- These need SVN access, so I can edit httpd.conf and snmpd.conf
- Monitor throughput on mississippi itself.
- Fix the kludge on httpd.conf I did.
