Queries the number of alert logs that were generated during each interval of a time period.

This topic provides an example on how to query the number of alert logs of Elastic Compute Service (ECS) from the cloud service dimension.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes DescribeAlertLogHistogram

The operation that you want to perform. Set the value to DescribeAlertLogHistogram.
StartTime Long No 1609988009694

The start timestamp of the alert logs to be queried. Unit: milliseconds.
EndTime Long No 1609989009694

The end timestamp of the alert logs to be queried. Unit: milliseconds.
PageNumber Integer No 1

The number of the page to return. Default value: 1
PageSize Integer No 10

The number of entries to return on each page. Default value: 10.
SearchKey String No alert

The keyword based on which the alert logs to be queried are searched.
GroupId String No 7301****

The ID of the application group.
Product String No ECS

The abbreviation of the service name.
Namespace String No acs_ecs_dashboard

The namespace of the cloud service.

Note For more information about the namespaces of cloud services, see Appendix 1: Metrics.
Level String No P4

The level and notification method of the alert. Valid values:

  • P4: Alert notifications are sent by using emails and DingTalk chatbots.
  • OK: No alert is generated.
SendStatus String No 0

The status of the alert. Valid values:

  • 0: The alert is triggered or cleared.
  • 1: The alert is generated not during the effective period.
  • 2: The alert is muted and not triggered in a specified period.
  • 3: The host is restarting.
  • 4: Notifications are not sent for the alert.

When the value of the SendStatus parameter is 0, the value P4 of the Level parameter indicates a triggered alert and the value OK indicates a cleared alert.

ContactGroup String No ECS_Group

The alert group.
RuleName String No test123

The name of the alert rule.
MetricName String No cpu_total

The name of the metric.

Note For more information about the metrics of different cloud services, see Appendix 1: Metrics.
LastMin String No 360

The statistical period of alert logs. Unit: minutes.
GroupBy String No product

The dimension based on which data is aggregated. This parameter is similar to the Group By clause of SQL statements. Valid values:

  • product: aggregates data by cloud service.
  • level: aggregates data by alert level.
  • groupId: aggregates data by application group.
  • contactGroup: aggregates data by alert group.
  • product,metricName: aggregates data both by cloud service and by metric.
