Update

The Linux runner image now reports richer vitals, so you can spot CPU and memory starvation faster in your telemetry.

  • PSI is now enabled in the Linux Kata guest, letting vitals emit pressure metrics for CPU and memory.
  • A new cpu.busy.pct metric is computed from /proc/stat deltas, giving a guest-wide CPU utilization signal that works even when PSI is unavailable.
  • PSI fields are only emitted when /proc/pressure is present, so you no longer see empty values in your logs.

To use these improvements, update to the Docker image ghcr.io/tuist/tuist-linux-runner:0.4.0.
