Why TA-rapl exists
Power meters are free and already in your kernel. TA-rapl reports watts and kWh per package/DRAM/platform so per-host cost, PS sizing and capacity headroom become real numbers, not estimates.
What it collects
- Package, DRAM and platform power draw
- Cumulative kWh per host
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 (powercap sysfs) · powerstat optional.
