Stats and gauges

The header carries a fleet summary: per-status session counts, plus the total cost of every live agent's full process tree, shell and agent and children together.

header
agents total usage: cpu 12% · ram 8% · 6.2 GB

CPU is that tree's CPU time over the last poll as a share of total machine capacity, the same 0-100% unit the computer gauge uses. RAM is resident set as a share of installed memory, with the absolute size beside it. The selected session's detail line uses the same scale for that one session.

The machine gauges

GaugeWhat it measures
cpuWhole-machine utilization, 0-100%.
memUsed over total. On macOS this matches Activity Monitor's Memory Used: resident RAM minus free, speculative and reclaimable file cache. On Linux it is Total - MemAvailable, so file cache is not counted as used.
swapUsed over the current swap allocation. On macOS the swap file grows under pressure, so the denominator is the live size from vm.swapusage rather than a fixed partition.
diskFill of the root filesystem, used over used plus available, with free space from the kernel's available figure.
netUp and down rates on real NICs only. Loopback, utun, bridges and similar virtual interfaces are excluded.
tempcpu, gpu and soc in °C, each the hottest sensor in its category, sampled every five seconds.
Apple Silicon Its dies report as one soc figure rather than separate CPU and GPU lines. A reading appears when the machine exposes that sensor.
