Operate
Find where the flow needs attention.
Follow sources through pipelines to destinations. Inspect warnings, throughput, logs, and worker state to understand what is happening.
Trace the path
Trace sources through pipelines to destinations.
Throughput and warnings help you find the source, pipeline, or destination to investigate. Search by name or select a group to narrow the view.


Check the running version
Check worker health and running versions.
Compare a worker's commit with main to see which configuration it is running. Open a worker in Status for its owned partitions and thread detail.


See what needs action.
Warnings name the affected object and the condition behind it. Logs retain what was reported once a condition clears.
Delivery and recovery
Keep control when delivery fails.
If a destination becomes unreachable, Smeltr retries and holds the sources feeding it as buffers fill. If the destination refuses a record, choose whether to hold it, send it to another destination for investigation, or deliberately drop it.
Keep source records long enough to cover the outage and the time needed to catch up. If the destination chosen to keep refused records also fails, the affected input streams can still pause. Hold and retry delivery →
Workers connect. The leader coordinates.
Workers hold the data connections and initiate communication with the leader. The leader provides authoring, review, and a shared operating view.
Worker groups let separate environments run their own configuration while sharing reusable pipeline logic.
