Creates or modifies a log monitoring metric.

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 PutLogMonitor

The operation that you want to perform. Set the value to PutLogMonitor.
Aggregates.N.Alias String Yes Count

The alias of the aggregate function. Valid values of N: 1 to 10.
Aggregates.N.FieldName String Yes sourceCount

The name of the field to be aggregated. Valid values of N: 1 to 10.
Aggregates.N.Function String Yes count

The function that is used to aggregate the monitoring data of logs within an aggregation period. Valid values of N: 1 to 10. Valid values:

  • count: counts the number.
  • sum: calculates the total value.
  • avg: calculates the average value.
  • max: selects the maximum value.
  • min: selects the minimum value.
  • countps: calculates the counted number of the specified field divided by the total number of seconds of the aggregation period.
  • sumps: calculates the total value of the specified field divided by the total number of seconds of the aggregation period.
  • distinct: counts the number of logs where the specified field appears within the aggregation period.
SlsLogstore String Yes test-logstore

The name of the Log Service Logstore.
SlsProject String Yes test-project

The name of the Log Service project.
SlsRegionId String Yes cn-hangzhou

The ID of the region where the Log Service Logstore resides.
LogId String No 12345

The ID returned by Log Service.
MetricName String No cpu_total

The name of the log monitoring metric. For more information, see Appendix 1: Metrics.

MetricExpress String No {"extend":{"errorPercent":"5XXNumber/TotalNumber*100"}}

The extended field. The extended field allows you to perform basic operations on the aggregation results.

Assume that you have calculated TotalNumber and 5XXNumber by aggregating the data. TotalNumber indicates the total number of HTTP requests, and 5XXNumber indicates the number of HTTP requests whose status code is greater than 499. You can calculate the server error rate by adding the following formula to the extended field: 5XXNumber/TotalNumber*100.

JSON format: {"extend":{"errorPercent":"5XXNumber/TotalNumber*100"}}. Description:

  • extend: required.
  • errorPercent: the alias of the field generated in the calculation result. You can specify the alias as needed.
  • 5XXNumber/TotalNumber*100: the calculation expression.
GroupId String No 12345

The ID of the application group.
Groupbys.N.Alias String No CPUUtilization

The alias of the dimension based on which the data is grouped. Valid values of N: 1 to 10.

Groupbys.N.FieldName String No cpu

The name of the field specified as the dimension. Valid values of N: 1 to 10.

ValueFilterRelation String No and

The logical operator that is used between log filter conditions. The ValueFilter and ValueFilterRelation parameters must be used in pair. Valid values:

  • and
  • or
ValueFilter.N.Key String No lh_source

The name of the log field used for matching in the filter condition. Valid values of N: 1 to 10.

ValueFilter.N.Operator String No Operator

The method that is used to match the field value. Valid values of N: 1 to 10. Valid values:

  • contain
  • notContain
  • >: greater than
  • <: less than
  • >=: greater than or equal to
  • <=: less than or equal to
ValueFilter.N.Value String No test

The field value to be matched in the filter condition. Valid values of N: 1 to 10.
Tumblingwindows String No 60,300

The size of the tumbling window for calculation. Unit: seconds. The system performs an aggregation for each tumbling window.

Unit String No Percent

The unit.

Response parameters

Parameter Type Example Description
Code String 200

The HTTP status code.
LogId String 12345

The ID returned by Log Service. If the log monitoring metric is created or modified, the ID is returned.

Message String successful

The returned message. Valid values:

  • If the call is successful, the value of successful is returned.
  • If the call fails, an error message is returned. Example: alias of aggreate must be set value.
RequestId String BBD7B294-1325-46D1-BD08-848D6A6B9AC6

The ID of the request.
Success Boolean true

Indicates whether the call was successful. Valid values:

  • true: The call was successful.
  • false: The call failed.
