pfSense reporting wrong pppoe interface speed and cacti clipping the graph
Attempts to capture PPPoE interface traffic from pfSense (v2.2.x) generate a clipped rrd with Cacti.
On the Cacti machines change the 'max' setting in the rrd file.
rrd info before tuning:
# rrdtool tune marathon_-_pfsense_router_traffic_in_194.rrd DS[traffic_in] typ: COUNTER hbt: 600 min: 0.0000 max: 64000.0000 DS[traffic_out] typ: COUNTER hbt: 600 min: 0.0000 max: 64000.0000
To fix the rrd, use the -a command line option to set the 'max' setting for 'traffic_in' and 'traffic_out':
# rrdtool tune marathon_-_pfsense_router_traffic_in_194.rrd -a traffic_in:200000000 # rrdtool tune marathon_-_pfsense_router_traffic_in_194.rrd -a traffic_out:200000000
Verify the setting has been set:
# rrdtool tune marathon_-_pfsense_router_traffic_in_194.rrd DS[traffic_in] typ: COUNTER hbt: 600 min: 0.0000 max: 200000000.0000 DS[traffic_out] typ: COUNTER hbt: 600 min: 0.0000 max: 200000000.0000
