omni-slo-generator

All in one solution for calculating SLOs. Built on top of google/slo-generator.

How it works

1. Looks through a GCS bucket and finds all SLO manifests (example)
2. Calculates the SLOs according to shared configuration
3. Exposes calculated prometheus metrics
4. Sleeps for a given interval

Assumptions

Feel free to create a Pull Request that allows for more setups, as it is this project is meant to work in a very specific way:

• Made to run in GKE
• SLO manifests are stored in GCS bucket

What is it missing

Alerts still need to be created 'manually'. It's hard to have one way of alerting.

Why

Before this, we at Heureka Group ran slo-generator in API mode with a cronjob listing the bucket and pushing it to the API. This caused a number of issues. This solution should be way more efficient.

Developing

It's not out of the box ready. Because as everything, this is being put together in a bit of a rush.

1. In docker-compose
   1. Replace OMNI_SLO_GENERATOR_SLO_GCS_BUCKET with a bucket you want to test against
   2. Add SA credentials with permissions for that bucket into sample/credentials.json
   3. Adjust your desired backends in sample/config.yaml
