Intro

We support any agent that can send logs in the json format. It could be CNCF graduates, i.e. FluentD / FluentBit or other popular ones, like Logstash.

For the simplicity sake we will use FluentBit as simple, yet powerful and performant agent. For other OS and agents, please follow the steps on the onboarding screen in Logs.
