Install OpenTelemetry logging
Contents
PostHog Logs works with any OpenTelemetry-compatible client, so most languages don't need a PostHog-specific package. The JavaScript web, React Native, iOS, Android, and Flutter SDKs also have native logging.
Platforms
Note: Logs uses the OpenTelemetry Protocol (OTLP) standard. If your language isn't listed, check the OpenTelemetry documentation for compatible libraries.

"Native" means the PostHog SDK records the signal with no OpenTelemetry packages. "OpenTelemetry" means you send it with an OpenTelemetry SDK or Collector pointed at your PostHog OTLP endpoint (/i/v1/logs, /i/v1/traces, or /i/v1/metrics) and your project token. Every PostHog SDK also captures events natively. Prometheus exporters can send metrics through the metrics agent.
