Generic Interface - Traffic max link speed settings?

[francois_j]

Hello,

I have this nice graph that host an aberration. The graph bellow is made out of SNMP network interface query and graphed out of "Interface - Traffic (bits/sec, Total Bandwidth)"

I would like to specify the maximum value possible for the counter. The physical interface is a 100mbit link but it's connected to a 5mbit DSL line.

As you can see in the graph, 52mbit/sec isn't real.

Code: Select all

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=1233144619 \
--end=1233231019 \
--title="Gateway - Traffic - ppp0/9" \
--rigid \
--base=1000 \
--height=120 \
--width=500 \

You may change the maximum by using "rrdtool tune" against that very rrd file.

Thanks Gandalf,

Is "rrdtool tune" part of the Cacti interface or is this accessible only in CLI?

Thank you

Only CLI at this time.

[gandalf]

cli only, unfortunately
