Why TA-psi exists
PSI says "users are already waiting" before monitoring says anything is down. TA-psi streams per-cgroup cpu/memory/IO stall pressure so latency SLOs get defended at the first sign of contention.
What it collects
- cpu/memory/io stall pressure per cgroup
- Some/full stall percentages
Runs on stock tools
No daemons, no agents, no exotic collectors - it shells out to well-known CLIs or reads sysfs, and parses the result into Splunk events.
External tools used: None (PSI files); cgroupv2.
