What the header is telling you.

The header carries a fleet summary: per-status session counts, plus agents total usage: cpu N% · ram M% · X GB for every live agent's full process tree, shell and agent and children together.

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

• CPUWhole-machine utilization, 0-100%.
• MemoryUsed 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.
• NetworkUp and down rates on real NICs only. Loopback, utun, bridges and similar virtual interfaces are excluded.
• Temperaturecpu, gpu and soc in °C, each the hottest sensor in its category, sampled every five seconds. Apple Silicon reports its dies as one soc figure. A reading appears when the machine exposes that sensor.
