yapmtr

Yapmtr is a lightweight, open-source tool designed to collect, process, and report application performance metrics and traces for distributed systems. Its goal is to provide a simple, pluggable data pipeline that can export metrics to common backends such as Prometheus and InfluxDB, while supporting basic distributed tracing.

Yapmtr comprises a client agent that runs inside services and a central collector that aggregates data and forwards it to backends or stores it locally.

The data model centers on time-stamped events and metrics, including fields such as service name, operation, duration, status, and trace identifiers.

Configuration is YAML-based, and the system can be extended with plugins for extra collectors, exporters, or instrumentations.

First released in 2022 by an online community of contributors, yapmtr follows an permissive license and emphasizes portability across Linux and Windows.

In practice, it is used for teaching, small-scale testing, and as a stepping stone toward more feature-rich monitoring stacks.

Limitations include a relatively basic set of analytics and fewer integrations than established commercial or large-scale open-source projects.
