Configuring Prometheus

To configure Prometheus to send samples to this binary, add the following to your prometheus.yml:

remote_write:
  - url: "http://prometheus-timestream-adapter:9201/write"

:info: AWS Timestream has a very powerful query language and there is a Grafana Plugin supporting Timestream as a datasource. However, there is a basic reader implementation.

remote_read:
  - url: "http://prometheus-timestream-adapter:9201/read"

Access Prometheus Timestream Database

The Session will attempt to load configuration and credentials from the environment, configuration files, and other credential sources.
