Re: [Bloat] reatime buffer monitoring?

[Dev]

Okay, in case it’s of use to anyone else, here’s a quick howto for this tool:

apt-get install libncurses5-dev build-essential

git clone https://github.com/ffainelli/bqlmon.git 


cd bqlmon

make

./bqlmon -i eth0

HTH.

Since it looks like you have bql, this should work for the hardware queues: 
https://github.com/dtaht/bqlmon 

It might be nice to have a realtime monitor for the qdisc stats, but these can 
also change very quickly so looking at drops and marks, or other stats, can be 
useful as well.
