Change and Impact
To continuously improve the API usage experience, CloudMonitor will optimize the query behavior and pagination logic of certain OpenAPIs, with a gradual rollout planned to begin on July 7, 2026.
Affected APIs:
API Action | Version | Description |
DescribeMetricLast | 2019-01-01 | Query the latest metric data point |
DescribeMetricList | 2019-01-01 | Query time-series metric data (unpaged) |
DescribeMetricData | 2019-01-01 | Query time-series metric data (with pagination) |
DescribeMetricTop | 2019-01-01 | Query top-ranked metric values |
Impact Summary:
● If the actual number of data points returned by the above APIs is too large to be covered by the Length (number of records displayed per page), normal pagination may be affected. After the change takes effect, you can use NextToken (pagination cursor identifier) to ensure pagination works properly.
Action required
Check whether the returned result contains NextToken. If so, please use NextToken to continue paginating until the end. (This operation is only required when operating directly via API; no action is needed for other cases.)
