Substrates
The Substrates project is the reference implementation for the Substrates API and SPI. It defines various foundational interfaces employed across all Humainary observability instrument software libraries.
Serventis
The Serventis project is the reference implementation for the Services API and SPI. It offers a humane and scalable way to infer and reason about the state of systems of services in proposing a simplified model and superior means to reframe and contextualize data collected.
Kanalis
The Kanalis project is the reference implementation for the Channels API and SPI. It offers a generic data flow interface for moving in-memory data from producers to one or more consumers.
Calculis
The Calculis project is the reference implementation for the Counters API and SPI. A highly efficient and extensible implementation of contextual counters.
Inspectis
The Inspectis project is the reference implementation for the Observers API and SPI. An open and extensible observatory framework for building, layering, and composing observers and their state inspection models on top of protocol (primarily input) observability instruments.
Stakks
The Stakks project is the reference implementation for the Stacks API and SPI. It offers an open extensible library for collecting contextual execution stacks for named callsites.
