Using mrtg to monitor cable modem utilization
[first time went without a subject somehow...]
Hi,
Anyone still using mrtg these days? I'm trying to set up mrtg on my
fedora25 system connected to a cable modem (35Mbit up, 5Mbit down) on
one side and a gigabit ethernet on the other and can't figure out how
to reflect that in the config file.
Maybe you have an idea for monitoring utilization using another method?
I'm trying to set it up to determine utilization, so it's important to
define the upper bound for both upload and download. Is this possible?
If I recall, isn't there a way to define input max and output max?
I've run the following cfgmaker command:
# cfgmaker --ifref=descr --ifdesc=alias -zero-speed=5000000
mysnmppass(a)orion.example.com
Here is the ifconfig output for my system. I've also included the
generated cfgmaker output (with 'example' as my domain) below. I don't
understand why it's defined eth0 and eth1 as 125MBit when it's
connected to a bridge on a gigabit network, and why it's chosen
625kbit for br0 when I've tried to define it as 5Mbit.
