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

Queue Metrics

When AP_OTEL_QUEUE_METRICS_ENABLED=true and OTEL_EXPORTER_OTLP_ENDPOINT is set, the app container also exports BullMQ queue metrics to <endpoint>/v1/metrics every 60 seconds, so your monitoring stack receives queue depth without exposing any HTTP admin surface. The gauge covers all queues, including dedicated worker-group queues. Each data point carries service.name=activepieces-api and host.name resource attributes, so replicas of the app container produce distinguishable series.
Outbound requests from the app go through an SSRF filter that blocks private, loopback, and link-local IPs. If your OTLP collector resolves to a private IP (for example an in-cluster collector), add its IP or CIDR to the AP_SSRF_ALLOW_LIST environment variable.

​
Sampling Variables

Events with level warn or error are always kept regardless of sampling configuration. AP_OTEL_ENABLED=true enables the OTLP log drain; AP_OTEL_QUEUE_METRICS_ENABLED=true enables queue metrics export. OpenTelemetry tracing is not emitted.
