Hi again,
There is another thread with the same question.
You can use this to get tc output for rrd, with the classids replaced
with names. The names will always be the same.
---
#!/bin/bash
dev="$1"
cmd="cat"
# check FireQOS names for classes
if [ -f /var/run/fireqos/ifaces/$dev ]
then
name="`cat /var/run/fireqos/ifaces/$dev`"
if [ ! -z "$name" -a -f /var/run/fireqos/$name.conf ]
then
interface_classes=
. /var/run/fireqos/$name.conf
opts=
for n in $interface_classes_monitor
do
classid=`echo $n | cut -d '|' -f 3`
classname=`echo $n | cut -d '|' -f 2`
opts="$opts -e 's/ $classid / $classname /g'"
done
test ! -z "$opts" && cmd="sed $opts"
fi
fi
tc -s -d class show dev $dev | eval "$cmd"
---
You can also use netdata to monitor classes in realtime (per second charts):

demo:

check the QoS section.
