NAME¶

ap-mrtg, ap-rrd - AP statistics translators

SYNOPSIS¶

DESCRIPTION¶

ap-mrtg get stats from AP and return it in MRTG parsable format. The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network-links. MRTG generates HTML pages containing graphical images which provide a LIVE visual representation of this traffic. You may get it from: http://people.ee.ethz.ch/~oetiker/webtools/mrtg/. ap-rrd gets stats from an AP and writes them to an RRDtool database. RRDtool is a data logging and graphing system for time series data.

OPTIONS¶

-i ip

AP ip address

-c community

SNMP community string

-t type

Statistics type <w>ireless, <e>thernet, associated <s>tations or <l>ink quality in client mode;

-b bssid

Mac address of the AP to which get link quality.

-d db_file

Name of the rrdtool database to write to.

-v

report MRTG about problems connecting to AP - if you want to get report about when AP spot work enable it

-r

reset AP when getting LinkQuality stats

-h

print help screen

MRTG Configuration Example¶

Simple mrtg.cfg for get stats from Atmel based AP:

Link Quality stats¶

If the AP is not in client mode, it errors out. Grabbing the signal strength resets the ethernet and wireless stats and AP. It's safe do not use this type of stat. Optionally you may set mac address (bssid) of the AP to which getting link quality stats, by default used first returned AP. Simple mrtg.cfg for get stats from Atmel based AP with Link Quality and reset stats:

Target[ap_e]: `/usr/local/bin/ap-mrtg -i 192.168.0.1 -c "public" -t ethernet -v`
