Although using a tool such as Amazon Managed Grafana is the easiest way to view and query your metrics, Amazon Managed Service for Prometheus also supports several Prometheus-compatible APIs that you can use to query your metrics. For more information about all the available Prometheus-compatible APIs, see Prometheus-compatible APIs.
The Prometheus-compatible APIs use the Prometheus query language, PromQL, to
specify the data that you want to return. For details about PromQL and its syntax,
see Querying
Prometheus
When you use these APIs to query your metrics, the requests must be signed with
the AWS Signature Version 4 signing process. You can set up AWS Signature Version 4 to simplify the signing process. For more
information, see aws-sigv4-proxy
Signing through AWS SigV4 proxy can be performed using awscurl. The
following topic Using awscurl to query Prometheus-compatible
APIs walks you through using awscurl to set up AWS
SigV4.
