Get statistics about your query usage for each query - Amazon Managed Service for Prometheus

Get statistics about your query usage for each query

Query pricing is based on the total number of query samples processed in a month from executed queries. You can get statistics about each query that you make to keep track of your samples processed. The query response for a query or a queryRange API can include the statistics data about query samples processed by including the query parameter stats=all in the request. A samples object is created in the stats object and the stats data is returned in the response.

The samples object consists of the following attributes:

Attribute Description
totalQueryableSamples Total number of query samples processed. This is the information to be used for billing.
totalQueryableSamplesPerStep The number of query samples processed per each step. This is structured as an array of arrays with the timestamp in epoch and the number of samples loaded on the specific step.

Sample requests and responses that include the stats information in the response are as follows:

Example for query:
