The Open Telemetry community have developed a specification that describes how observability agents like Fluent Bit, Fluentd, OTel Collectors can be monitored, managed and configured. We have built an (Apache 2 licensed) implementation for Fluent Bit. We’d love it people take a look, try it out, and crucially give us constructive feedback, we're still in a Alpha/Beta phase - https://github.com/mp3monster/fluent-opamp/blob/main/README.md
