Function

This API is used to query the monitoring data of a specified partition of a stream.

Calling Method

For details, see Calling APIs.

URI

GET /v2/{project_id}/streams/{stream_name}/partitions/{partition_id}/metrics

Table 1 Path Parameters

Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID
stream_name	Yes	String	Stream name Maximum: 60
partition_id	Yes	String	Partition ID.Two partition ID formats are available:- shardId-0000000000- 0For example, if a stream has three partitions, the partition IDs are 0, 1, and 2, or shardId-0000000000, shardId-0000000001, and shardId-0000000002.

Table 2 Query Parameters

Parameter	Mandatory	Type	Description
label	No	String	Partition monitoring metric. (Either label or label_list must be specified. If both label_list and label exist, label_list is used.) total_put_bytes_per_partition: total input traffic in a partition (byte) total_get_bytes_per_partition: total output traffic in a partition (byte) total_put_records_per_partition: total number of input records in a partition total_get_records_per_partition: total number of output records in a partition Enumeration values: total_put_bytes_per_partition total_get_bytes_per_partition total_put_records_per_partition total_get_records_per_partition
label_list	No	String	List of labels separated by commas (,) to query multiple labels in batches. (Either label or label_list must be specified. If both label_list and label exist, label_list is used.)
start_time	Yes	Long	Monitoring start time, which is a 10-digit timestamp
end_time	Yes	Long	Monitoring end time, which is a 10-digit timestamp
