Labels String [{"groupFlag":true}]

The tags of the service. Tags are used to filter services.

Tags are returned in the following format: [{"name":"Tag key","value":"Tag value"}, {"name":"Tag key","value":"Tag value"}]. The following tags are commonly used:

  • alertUnit: the unit of the metric value in alerts.

    If the unit is small, the original metric value may be too large. In this case, you can use the alertUnit tag to specify an appropriate unit. This tag is used in Cloud Monitor.

  • minAlertPeriod: the minimum time interval to report a new alert. The interval is usually set to 1 minute.
  • metricCategory: the specification of the service. Example: kvstore_sharding.

    An Alibaba Cloud service may have different specifications that are defined in the same namespace. You can use this parameter to distinguish between service specifications.

  • is_alarm: specifies whether an alert rule can be set.

    We recommend that you do not use the special tags in the Cloud Monitor console.
