Querying Prometheus metrics via API and Grafana

You can use the Prometheus-compatible API and Grafana to query the metrics ingested to Prometheus. Let’s look at how to do it in the following sections.

Querying Prometheus metrics using Prometheus APIs

To query AMP using the Prometheus-compatible APIs, you need to sign your requests using the AWS Signature Version 4 process (see https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html). You can accomplish this requirement in many different ways, and between them, you can use a proxy such as the AWS Sig4 Proxy (see https://github.com/awslabs/aws-sigv4-proxy) or use the awscurl tool (see https://github.com/okigan/awscurl).

   $ pip3 install awscurl

2. To execute requests, you need the Prometheus...
