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.
