List of metrics exposed by stellar-core |
stellar-core uses libmedida for computing metrics, a detailed description can be found at http://dln.github.io/medida/
Tracks a value in absolute terms of a base unit.
Tracks aggregates (count, min, max, mean, percentiles, etc) for samples expressed in arbitrary base unit.
Tracks aggregates (count, min, max, mean, percentiles, etc) of samples expressed in units of time.
Tracks aggregates (count, min, max, mean, etc), rate (1m, 5m, 15m) for samples expressed in base unit.
Tracks multiple timers organized into disjoint buckets.
