How to monitor Golden signals in Kubernetes
Most of this doc is Kubernetes specific, but this "golden signals" idea is interesting; basically, the four metrics of requests per second, average request latency, CPU usage on service fleet, errors per second. I would modify by adding the P99 or P99.9 request latency, and representing errors per second as a proportion of that period's request-per-second figure.

open source, system-level exploration: capture system state and activity from a running Linux instance, then save, filter and analyze.
Think of it as strace + tcpdump + lsof + awesome sauce.
With a little Lua cherry on top.


This sounds excellent. Linux-based, GPLv2.
