查询分区监控
功能介绍
本接口用于查询通道指定分区的监控数据。
调用方法
请参见如何调用API。
URI
GET /v2/{project_id}/streams/{stream_name}/partitions/{partition_id}/metrics
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
project_id |
是 |
String |
项目ID。 |
stream_name |
是 |
String |
通道名称。 最大长度:60 |
partition_id |
是 |
String |
分区编号。可定义为如下两种样式:- shardId-0000000000- 0比如一个通道有三个分区,那么分区标识符分别为0, 1, 2,或者shardId-0000000000, shardId-0000000001, shardId-0000000002 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
label |
否 |
String |
分区监控指标。(label与label_list必须二选一,label_list与label同时存在时,以label_list为准)
枚举值:
|
label_list |
否 |
String |
使用label用逗号拼接组成,用于批量查询多个label的指标。(label与label_list必须二选一,label_list与label同时存在时,以label_list为准) |
start_time |
是 |
Long |
监控开始时间点,10位时间戳。 |
end_time |
是 |
Long |
监控结束时间点,10位时间戳。 |
请求参数
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
X-Auth-Token |
是 |
String |
用户Token。 通过调用IAM服务获取用户Token接口获取(响应消息头中X-Subject-Token的值)。 |
