traceql

OpenTelemetry signal storage

Drop-in Prometheus / Loki / Tempo HTTP gateway for ClickHouse. Translate PromQL, LogQL, and TraceQL into optimized CH SQL — keep Grafana, swap the backend.

A small-footprint, embeddable observability database for Rust.

Go binding of https://github.com/moriyoshi/imbh. Features zero-copy, near zero-overheads in the async boundary.

Reproducible docker-compose benchmark: oteldb vs Prometheus, VictoriaMetrics, Mimir, GreptimeDB, gigapipe, Loki, VictoriaLogs, Tempo, VictoriaTraces across PromQL/LogQL/TraceQL

Serve the Grafana Tempo query API from an Axiom dataset by translating TraceQL to APL

C/C++ bindings for imbh (https://github.com/moriyoshi/imbh)

Tempo provider for mgtt — per-span SLO checks (current_p99, breach_duration, error_rate) against Grafana Tempo's TraceQL Metrics.

Standalone Go parser and AST for Grafana Tempo's TraceQL.

Testing framework for code that enforces a rule: auth checks, sandboxes, agent guardrails. OpenTelemetry spans as the test interface, an independent witness for what actually happened, and mutation testing that proves the tests fail when a check is removed.

Observability workspace for AgentGateway built around Vector and the VictoriaMetrics stack.

Dependency-light Rust parser for a supported TraceQL subset, with structured errors.

Structured query DSL engine for JSON and log analysis.

Go library and CLI for extracting structural references from LGTM-stack queries.
