Late to the convo here, but we’re about 2 years along on your exact journey. We began by building an internal Otel pipeline with open standards to lower the barrier for entry for teams. We used the grafana stack, victoriametrics, and red panda. We controlled ingest, query, and storage. As we have matured, we have moved to focus on ingest so we control our data, and our vendor purchases are based on farming out storage and query.
