OpenTelemetry Collector
Vendor-agnostic telemetry pipeline that receives, processes, and exports metrics, traces, and logs from any source to any backend.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Credentials in YAML config — use env var substitution or secrets manager integration
⚡ Reliability
Best When
Building a multi-signal, multi-backend observability pipeline where vendor lock-in is a concern.
Avoid When
You only need basic logging without traces/metrics — simpler tools reduce operational overhead.
Use Cases
- • Receive OTLP traces from microservices and export to both Jaeger and Datadog simultaneously
- • Tail-sample high-latency traces (>500ms) using probabilistic sampler processor
- • Collect host metrics via hostmetrics receiver and forward to Prometheus remote write
- • Transform and filter telemetry data using OTTL (OTel Transformation Language) before export
- • Scrape Prometheus metrics endpoints and convert to OTLP for Grafana Cloud ingestion
Not For
- • Simple single-destination setups where vendor SDKs export directly
- • Log management with search — use Loki or Elasticsearch for log storage
- • Application instrumentation — use OpenTelemetry SDK in your app code
Interface
Authentication
Self-hosted; TLS + auth extensions (basicauth, bearertokenauth, oauth2client) available per exporter
Pricing
Fully open source; Contrib distribution includes community-maintained components
Agent Metadata
Known Gotchas
- ⚠ Core vs Contrib distributions differ in available components — verify receiver/exporter availability before deploying
- ⚠ OTTL transformation syntax changed between versions — validate configs against specific collector version
- ⚠ Memory limiter processor is required to prevent OOM; missing it is a common production failure
- ⚠ Tail sampling requires all spans for a trace to reach the same collector instance — stateful routing needed
- ⚠ Prometheus scrape receiver blocks the collector pipeline on slow targets — use timeouts aggressively
