Observability (o11y) helpers for the NEAR codebase.
This crate contains all sorts of utilities to enable a more convenient observability implementation in the NEAR codebase.
The are three infrastructures:
tracing, for structured, hierarchical logging of events (see [default_subscriber] function function in particular)metrics-- convenience wrappers around prometheus metric, for reporting statistics.io-tracer-- custom infrastructure for observing DB accesses in particular (mostly for parameter estimator)
