This release improves Linux runner health monitoring by enabling PSI in the kata guest and adding a CPU-busy percentage metric to runner vitals.
- Linux runners now enable kernel Pressure Stall Information (PSI), so CPU and memory pressure fields are populated instead of returning empty.
- Runner vitals now include a guest-wide CPU-busy percentage, giving you a reliable CPU-starvation signal independent of PSI.
- PSI fields are omitted from vitals when the guest does not expose
/proc/pressure, so logs stay clean.
