Activepieces exports structured logs via evlog. Each API request and worker job execution emits a single wide-event JSON object including duration, status, and sampling context.
Log Export Variables
| Variable | Description | Default Value | Example |
|---|
AP_OTEL_ENABLED | Export logs via OTLP log drain (no traces or metrics) | false | true |
OTEL_EXPORTER_OTLP_ENDPOINT | OTLP endpoint for log export | None | https://your-collector:4317 |
OTEL_EXPORTER_OTLP_HEADERS | Headers for OTLP exporter (comma-separated key=value pairs) | None | Authorization=Bearer token |
Sampling Variables
| Variable | Description | Default Value |
|---|
AP_LOG_SAMPLE_RATE_INFO | Percentage of info-level events to keep (0–100) | 100 |
AP_LOG_KEEP_SLOW_MS | Always keep requests slower than this threshold (ms) | 2000 |
Events with level warn or error are always kept regardless of sampling configuration.
AP_OTEL_ENABLED=true enables the OTLP log drain only — OpenTelemetry tracing and metrics are no longer emitted.
