Venator is a application for recording, viewing, and filtering logs and spans from programs instrumented with the Rust tracing crate or using OpenTelemetry. It is purpose-built for rapid local development.
Binaries are pre-built and available in the releases page for:
- Windows (x64)
- MacOS (Intel, Apple silicon)
Compiling and installing venator from source with Cargo (requires Rust 1.76 or
newer):
cargo install venator-app
Configure your program's OpenTelemetry SDK to export logs and traces to
127.0.0.1:8362 (Venator's default listening port) and to use grpc or
http/protobuf.
In your instrumented program:
[dependencies]
venator = "1.1.0"use venator::Venator;
Venator::default().install();See the documentation for more.
Events can be viewed narrowed by timespan and filtered by attributes, level, and other properties. The table of records can include columns of custom properties. The graph shows the counts by level at each bar.
Spans can likewise be narrowed by timespan and filter. A detail pane can show all the properties of selected events and spans. The graph shows spans layered hierarchically.
Traces can be viewed that show both events and spans within a single execution.
