Features

💡 qryn independently implements popular observability standards, protocols and query languages


👁️ Built-In Explorer

qryn ships with view - our zero dependency, lightweight data explorer for Logs, Metrics and Traces


➡️ Ingest

📚 OpenTelemetry

qryn is officially integrated with opentelemetry supports any log, trace or metric format
Ingested data can be queried using any of the avialable qryn APIs (LogQL, PromQL, TraceQL)

💡 No modifications required to your opentelemetry instrumentation!

📚 Native

qryn supports native ingestion for Loki, Prometheus, Tempo/Zipkin and many other protocols
With qryn users can push data using any combination of supported APIs and formats

💡 No opentelemetry or any other middlewayre/proxy required!


⬅️ Query

📚 Loki + LogQL

Any Loki compatible client or application can be used with qryn out of the box

qryn implements the Loki API for transparent compatibility with LogQL clients

The Grafana Loki datasource can be used to natively browse and query logs and display extracted timeseries

🎉 No plugins needed
👁️ No Grafana? No problem! Use View


📈 Prometheus + PromQL

Any Prometheus compatible client or application can be used with qryn out of the box

qryn implements the Prometheus API for transparent PromQL compatibility using WASM 🏆

The Grafana Prometheus datasource can be used to natively to query metrics and display timeseries

🎉 No plugins needed
👁️ No Grafana? No problem! Use View


🕛 Tempo + TraceQL

qryn implements the Tempo API for transparent compatibility with TraceQL clients.

Any Tempo/Opentelemetry compatible client or application can be used with qryn out of the box

The Tempo datasource can be used to natively query traces including TraceQL and supporting service graphs

🎉 No plugins needed
👁️ No Grafana? No problem! Use View


🔥 Pyroscope + Phlare

qryn implements the Pyroscope/Phlare API for transparent compatibility with Pyroscope SDK clients.

Any Pyroscope SDK client or Pyroscope compatible agent can be used with qryn out of the box for continuous profiling



📚 Vendors Compatibility

qryn can ingest data using formats from Grafana, InfluxDB, DataDog, Elastic and other vendors.


With qryn and grafana everything just works right out of the box:

  • Native datasource support without any plugin or extension
