Description

We need a simple and modern way to manage our logs so that when an issue
occurs, we can debug it easily. We now have a way to do this via
Fluent Bit Loki Plugin. Reasons for going with fluent-bit:

  • Very Very low memory footprint, this means we can run this service on
    a light machine and not have to worry about it, we can also share the
    host for main backend and fluent-bit.
  • Very customizable - Fluent Bit has tons of plugins, which means we can
    redirect our logs to a different log management service, receive logs
    in various ways, filter log messages, etc.
  • Support for multiple outputs - This is a strong feature of FluentBit.
    This lets us output our logs to Granfa Loki, Logzio, Datadog, StdOut, etc all
    at the same time.

Notes from this PR:

I've included an example config file for fluent-bit at telemetry/fluent-bit/fluent-bit.toml.example which we can use for deploying a sort of sidecar for logs.

  • Fluent Bit should be running before the main app launches
  • We send all the logs over HTTP to our local-to-server fluent-bit instance and FluentBit forwards those those logs to Grafana Loki (we can actually change the output to other providers too)
