Kafka Connect Connector Source Task Metrics Metrics
In addition to these base metrics, many aggregate metrics are available.
If an entity type has parents defined, you can formulate all possible
aggregate metrics using the formula
base_metric_across_parents.
In addition, metrics for aggregate totals can be formed by adding the prefix
total_ to the front of the metric name.
Use the type-ahead feature in the Cloudera Manager chart browser to find the exact aggregate metric name, in case the plural form does not end in "s".
For example, the following metric names may be valid for Kafka Connect Connector Source Task Metrics:
-
kafka_connect_connector_source_task_metrics_poll_batch_avg_time_ms_across_clusters -
total_kafka_connect_connector_source_task_metrics_poll_batch_avg_time_ms_across_clusters
Some metrics, such as alerts_rate, apply to nearly every metric context. Others only apply to a
certain service or role.
| Metric Name | Description | Unit | Parents | CDH Version |
|---|---|---|---|---|
| kafka_connect_connector_source_task_metrics_poll_batch_avg_time_ms | The average time in milliseconds taken by this task to poll for a batch of source records. | message.units.milliseconds | cluster, kafka, kafka-kafka_connect, rack | CDH 5, CDH 6, CDH 7 |
| kafka_connect_connector_source_task_metrics_poll_batch_max_time_ms | The maximum time in milliseconds taken by this task to poll for a batch of source records | message.units.milliseconds | cluster, kafka, kafka-kafka_connect, rack | CDH 5, CDH 6, CDH 7 |
| kafka_connect_connector_source_task_metrics_source_record_active_count | The most recent number of records that have been produced by this task but not yet completely written to Kafka. | records | cluster, kafka, kafka-kafka_connect, rack | CDH 5, CDH 6, CDH 7 |
| kafka_connect_connector_source_task_metrics_source_record_active_count_avg | The average number of records that have been produced by this task but not yet completely written to Kafka. | records | cluster, kafka, kafka-kafka_connect, rack | CDH 5, CDH 6, CDH 7 |
| kafka_connect_connector_source_task_metrics_source_record_active_count_max | The maximum number of records that have been produced by this task but not yet completely written to Kafka. | records | cluster, kafka, kafka-kafka_connect, rack | CDH 5, CDH 6, CDH 7 |
| kafka_connect_connector_source_task_metrics_source_record_poll_rate | The average per-second number of records produced/polled (before transformation) by this task belonging to the named source connector in this worker. | records per second | cluster, kafka, kafka-kafka_connect, rack | CDH 5, CDH 6, CDH 7 |
| kafka_connect_connector_source_task_metrics_source_record_poll_total | The number of records produced/polled (before transformation) by this task belonging to the named source connector in this worker, since the task was last restarted. | records | cluster, kafka, kafka-kafka_connect, rack | CDH 5, CDH 6, CDH 7 |
| kafka_connect_connector_source_task_metrics_source_record_write_rate | The average per-second number of records output from the transformations and written to Kafka for this task belonging to the named source connector in this worker. This is after transformations are applied and excludes any records filtered out by the transformations | records per second | cluster, kafka, kafka-kafka_connect, rack | CDH 5, CDH 6, CDH 7 |
| kafka_connect_connector_source_task_metrics_source_record_write_total | The number of records output from the transformations and written to Kafka for this task belonging to the named source connector in this worker, since the task was last restarted. | records | cluster, kafka, kafka-kafka_connect, rack | CDH 5, CDH 6, CDH 7 |
