DataHub supports the following monitoring metrics:
Name | Description |
Subscription delay time | The difference between the subscription point and the current time (unit: seconds) |
Consume delay time | The maximum consumption latency of the current subscription across all shards (unit: seconds) |
Comsume record stacked | The total number of messages pending consumption in the current subscription across all shards (unit: records) |
If you use the Kafka consumer protocol to read DataHub data, you cannot use the subscription delay time and consume delay time metrics for monitoring.
