OpenTelemetry solved a real problem. Before it, every APM vendor had you install a proprietary agent, which meant switching vendors meant re-instrumenting everything. OTel gave engineering teams a vendor-neutral way to generate traces, metrics, and logs once and send them wherever they wanted. That part of the pitch is true, and open-source deserves credit for it. What gets left out of most OTel adoption conversations is what happens after the SDKs are wired up. The framework is free. Running it well is not. The Pain Points That Show Up After Rollout Collector sprawl. A production OTel deployment usually means running collector instances per region or per cluster, tuning batch and memory limiter settings, and watching for the collector itself becoming a bottleneck under load. This is the infrastructure your team now owns and patches, on top of the infrastructure it was supposed to help you monitor. Storage and retention decisions become your job. OTel defines how telemetry is generated and transported, not where it lives. Teams end up choosing and operating a backend, commonly a trace store, a time-series database (TSDB) for storing and querying metrics over time, and a log index, then building the queries and dashboards to make that data usable. Every version upgrade across that chain is a coordination exercise. Cross-signal correlation requires continuous engineering. Traces, metrics, and logs arriving in three different systems does not automatically mean an engineer can jump from a slow span to the exact log line or the query that caused it. Building that correlation …
