rss-ladder don't work on stand without NUMA nodes. Workaround --no-color

[strizhechenko]

[root@reductor-stand statistic]# rss-ladder eth1 --cpus 0
- distribute interrupts of eth1 (-rx-) on socket None

--no-color is workaround

[anton-cheloshkin]

у меня та же проблемка. Без NUMA nodes

rss-ladder eth1 1 --no-color

А зачем параметр 1 указываете, если NUMA нет?

К слову, пришлите вывод команд:

python --version
pip show netutils-linux
cat /etc/issue
uname -a
lscpu
lscpu -p

У вас однопроцессорная система, вы пытаетесь переопределить автоматический выбор подходящего процессора и использовать ядра второго процессора параметром: rss-ladder eth1 1.

Запускайте просто и всё будет в порядке:

rss-ladder eth1
