pub fn record_engine_gc(
_collections: i64,
_pause_millis: i64,
heap_used: u64,
heap_max: u64,
)Expand description
Isolate-wide GC and heap, polled from the engine rather than parsed from a
log the graal fleet does not write. Cumulative, so
rate(engine_gc_pause_millis_total) / 1000 is the fraction of wall clock
stopped, which is the figure that identified #684. Every room on the node
shares one isolate, so a collection here stops all of them at once.
The collection counters carry a collector label and are emitted by
record_engine_gc_collector; emitting an unlabelled copy of the same name
here would double every sum.
