Quick, smart alerting with incidence triage.

Reduce on-call burden. Every alert is paired with a detailed knowledge graph of your data infrastructure — so you understand how everything fits together. A shared context with your team to solve incidents faster.

Anomaly investigation starts the moment alerts are fired. Pulls deep context from your telemetry lake to pinpoint and assist with the root cause before downstream impacts.

Integrations

Production intelligence, built on open standards. OpenTelemetry (OTel) captures execution traces for your Spark jobs, while OpenLineage (OLin) maps your high-level data flow context. Works with any Spark deployment and is fully open source. No vendor lock-in.
