One reading of every counter the monitor shows, in integers because it travels on the wire (crates/sprawling/Spec.lean §8-94, §8-129-6).

Fields

core_cpu_permille: u64

core_private_bytes: u64

core_working_set_bytes: u64

core_read_bytes: u64

core_written_bytes: u64

machine_cpu_permille: u64

machine_available_bytes: u64

volume_free_bytes: u64

ledger_queue_depth: u64

durable_lag: u64

relay_p50_nanos: u64

event_to_screen_p50_nanos: u64

queued_runs: u64

view_backlog: u64

Committed records the writer has handed the view thread that are not yet folded and broadcast (crates/sprawling/Spec.lean §8-123).

read_nanos: u64

How long the beat before this one took to read the counters, by the sampler’s own monotonic clock; 0 on the first beat (crates/sprawling/Spec.lean §8-129-6).

beat_ms: u64

The beat this reading was sampled at, in milliseconds (§8-47i): what the page’s beat control reads as the current setting.
