CPU detailed statistics for TSDB | ||
This plugin tracks, for all CPUs: | ||
- user % | ||
- nice % | ||
- system % | ||
- interrupt % | ||
- idle % | ||
Requirements : | ||
- FreeBSD : top | ||
- Linux : mpstat | ||
In addition, for FreeBSD, it reports : | ||
- load average (1m, 5m, 15m) | ||
- number of processes (total, starting, running, sleeping, stopped, zombie, waiting, lock) | ||
- memory statistics (bytes) (active, inact, wired, cache, buf, free) | ||
- arc statistics (bytes) (total, mru, mfu, anon, header, other) | ||
- swap statistics (bytes) (total, free, inuse, in/s, out/s) | ||
