Uptrace

Uptrace is an open source APM covering distributed tracing, metrics and logs behind a single interface. Instead of running a separate system for each signal, you send everything through OpenTelemetry and query it from one place, with a query builder, dashboards and alerting on top.

Storage is ClickHouse, with PostgreSQL holding metadata such as metric names and alert definitions. That pairing is where the cost argument comes from: a one kilobyte span compresses to roughly forty bytes on disk, a single core processes more than ten thousand spans per second, and one server can carry billions of spans and metrics.

Querying and alerting are built around shapes engineers already know.

• SQL-like span queries: spans and logs are aggregated with a language close to SQL.
• PromQL-like metric queries: metrics use a syntax Prometheus users will recognize.
• Prebuilt dashboards: more than fifty dashboards appear automatically once matching metrics start arriving.
• Alerting: rules over spans, logs and metrics notify by email, Slack, webhook or AlertManager.
• Grafana compatibility: Uptrace can be configured as a Tempo or Prometheus data source.

Ingestion accepts OpenTelemetry, Prometheus, Vector, FluentBit and CloudWatch among others, and a service graph plus chart annotations tie deploys to what the charts show. Users and projects are managed from a YAML config, and single sign-on works over OpenID Connect with Keycloak, Google Cloud and Cloudflare. A cloud demo needs no login, and a Docker example gets a local instance running quickly.
