biometrics

Biometrics provide the vitals of a process in the form of counters, gauges, moments, and histograms. Collectively, these sensors paint a picture of what's happening within a process in timeseries form.

For a prometheus-compatible emitter, see biometrics_prometheus.

Status

Active development. Biometrics is likely to change in the near future in backwards-incompatible ways. Planned changes will affect how to register sensors in order to solve the dependency graph problem.

Scope

Biometrics will provide core sensor types and a plaintext emitter for counter, gauge, and moments types. Protocol buffer definitions for sensor readings can be found in the biometrics_pb

Warts

• The blue repo currently is not uniform in its register_biometrics functions. The convention is that a public method should not call other public methods.

Updating

• 0.2.0 -> 0.3.0: API changes to remove ingest_swizzle. It's recommended to have a crate transitively register its own modules and then have the main function register each crate's root registration function.
