Telemetry collection seems very straightforward at first glance: just use Fluent Bit or Fluentd for logs, Prometheus for metrics and call it a day. But problems arise when we want the best performance or simplicity of the solution. It’s hard to maintain three different agents, with three different configurations and documentation in three different places. In the talk, Perk discusses why his team replaced Fluent Bit, Fluentd and Prometheus with OpenTelemetry Collector and the challenges they faced along the way. Most importantly - is there a happy ending?

Product manager by day, developer by night. Remote work practitioner.

My dev journey started with a copy-book and a pencil for C64 picture bytes calculations. Since then I have been involved in many different projects - ranging from security in message queues to Hadoop; from monolith to microservices; from bare metal to Kubernetes; from software tester, through dev and ops to lead and manager.

I love automation and believe that Linux is the best thing since sliced bread. Well, maybe after Vim.
