When we use node_cpu_seconds_total metric of Node Exporter, as seen on attached first image, Prometheus returns us total CPU usage seconds for all 8 process modes as we know.
Node Exporter CPU modes coming with node_cpu_seconds_total metric
I made lots of search to understand what those modes stand for and I almost found all of them in an article, but "nice" mode. Does anyone know what this "nice" mode stands for?
Nice: The user code can be executed in “normal” priority, or various degrees of “below normal” priority. You can, for example, run some kind of report generation process at a lower priority and interactive processes at normal priority. Nice is when the CPU is executing a user task having below-normal priority. from this article
