Prometheus but for logs. This egg is for Loki instance only! You usually need pushing agents like Promtail to put logs in this
Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by Prometheus. It is designed to be very cost effective and easy to operate.
To get logs "into" Loki you need a scrape agent, such as official Promtail or a library for your app that can push logs through HTTP endpoint (gRPC endpoint is disabled in Docker enviroment by default)
As this egg sets up Loki in single node mode, it can consume a lot of disk space really fast. It is possible to setup different kind of storages for different parts of Loki files. For further information refer to official Loki documentation.
To get started, you can go with a minimum of 3GB RAM and >=2.5GB disk space.
Keep in mind that those numbers can grow pretty quick!
