Grafana Agent on-premises!

Ever wondered if you can use the easy peasy Grafana Agent without Grafana Cloud?

For example, along with your ON-PREMISES deployments of Prometheus, Loki and Tempo? Answer is YES, OF COURSE.

This repo just shows the basics and it's a one-shot working config to build on.

Remote write

The harder bits to set up are the remote_write configs for Prometheus, Loki, etc. For example, for Prometheus:

metrics:
  global:
    remote_write:
      - url: http://prometheus:9090/api/v1/write

and for Loki

logs:
  configs:
    ..
    clients:
      - url: http://loki:3100/loki/api/v1/push

You can even configure different scrapes to send metrics to distinct remote write endpoints, but I won't be going into that for now.

Please have a look at

./conf/grafana-agent/agent-linux.yaml

The rest is basically boilerplate config.

How to test it yourself

Clone the repo

docker-compose up -d

In your browser, go to localhost:3000 and log into Grafana with admin/admin. Click explore, select one of the provisioned Prometheus or Loki datasources and begin querying your scraped metrics and logs!

NEVER, EVER use this in production

This repo lacks any kind of security, scalability that you DEFINITELY NEED for anything close to a production workload.
