Worker Metrics
The worker metrics group contains per-worker general metrics. The available metrics are:
- Connectors Count
- Connector Startup Attempts
- Connector Startup Failure Total
- Tasks Count
- Tasks Startup Attempts Total
- Tasks Startup Failure Total
See also the Kafka Connect metrics available in the monitoring api.
Connectors Count
The connectors count metric shows the number of connectors currently assign to each node.
Connector Startup Attempts
The connector startup attempts shows the number of times connectors have attempted to start up on a per worker basis. Unexpectedly high numbers here may indicate integration failures in your systems.
Connector Startup Failure Total
The connector startup failure total show the number of times connectors have failed to startup and create tasks. Unexpectedly high numbers here may indicate a problem with your connector code or configuration.
Tasks Count
The tasks count metric shows the number of worker tasks currently assigned to each worker node in your cluster. This will help discover nodes that are overloaded or non-functional.
Tasks Startup Attempts Total
The tasks startup attempts shows the number of times tasks have attempted to start up on a per worker basis. Unexpectedly high numbers here may indicate integration failures in your systems.
Tasks Startup Failure Total
The tasks startup failure total show the number of times tasks have failed to startup on a per worker basis. Unexpectedly high numbers here may indicate a problem with your task and connector code or configuration.
