Metrics data

Last Updated: Aug 04, 2020

This section describes how to use the Alibaba Cloud OpenAPI or the CloudMonitor SDK to query Function Compute (FC) metrics from CloudMonitor Service (CMS).


FC metrics data is available for querying under CMS project: acs_fc.

Sample Java code using CMS SDK:

  1. QueryMetricRequest request = new QueryMetricRequest();
  2. request.setProject("acs_fc");

StartTime and EndTime

CloudMonitor metrics data time range is specified by (StartTime, EndTime] inputs where StartTime timestamp is exclusive and EndTime timestamp is inclusive.

CloudMonitor data retention is 31 days. The interval between StartTime and EndTime cannot exceed 31 days, and data earlier than 31 days cannot be queried.

For more detailed parameters information, see CloudMonitor Interface introduction.

Sample Java code using CMS SDK:

  1. request.setStartTime("2017-04-26 08:00:00");
  2. request.setEndTime("2017-04-26 09:00:00");


FC metrics are dimensioned into region, service, and function.

  • Set Dimensions as the following to access regional dimension metrics data:
  1. {"region": "${your_region}"}
  • Set Dimensions as the following to access service-dimension metric data:
  1. {"region": "${your_region}", "serviceName": "${your_serviceName}"}
  • Set Dimensions as the following to access function-dimension metric data:
  1. {"region": "${your_region}", "serviceName": "${your_serviceName}", "functionName": "${your_functionName}"}

Note: “Dimensions” parameter is a JSON string and has only one Key-Value pair for FC.

Sample Java code using CMS SDK:

  1. request.setDimensions("{\"region\":\"your_region\"}");


FC metrics are aggregated in 60s period.Sample Java code using CMS SDK:

  1. request.setPeriod("60");


Sample Java code using CMS SDK:

  1. request.setMetric("your_metric");

The following table lists all the supported metric keys.
