# Open Telemetry default properties

> Default OpenTelemetry configuration properties for FlowX.AI services, including Java agent settings, exporters, and resource attributes.

* `otel.resource.attributes=service.name=flowx-process-engine,service.version=1.1.1`: Environment variable.

<Info>
  Will be overridden as environment variable by Kubernetes operator. Useful for local development.
</Info>

### Java agent configuration

* `otel.javaagent.enabled=true`
* `otel.javaagent.logging=simple`
* `otel.javaagent.debug=false`

### Disable OTEL SDK

* `otel.sdk.disabled=false`

## Exporters configuration (common config for all exporters)

* `otel.traces.exporter=otlp`
* `otel.metrics.exporter=otlp`
* `otel.logs.exporter=otlp`

### OTLP exporter

* `otel.exporter.otlp.endpoint=http://localhost:4317`

<Info>
  Endpoint will be overridden by Kubernetes operator. Useful for local development.
</Info>

* `otel.exporter.otlp.protocol=grpc`
* `otel.exporter.otlp.timeout=10000`
* `otel.exporter.otlp.compression=gzip`
* `otel.exporter.otlp.metrics.temporality.preference=cumulative`
* `otel.exporter.otlp.metrics.default.histogram.aggregation=explicit_bucket_histogram`

### Tracer provider

<Info>
  `SdkTracerProvider` specific configuration options.
</Info>

<Info>
  * Sampler: see the [OpenTelemetry sampler documentation](https://github.com/open-telemetry/opentelemetry-java/blob/main/sdk-extensions/autoconfigure/README.md#sampler)
  * The default sampler is: `parentbased_always_on`
  * To disable FlowX technical spans, add sampler: `fxTechnicalSpanFilterSampler`
</Info>

* `otel.traces.sampler=parentbased_always_on`

### Batch span processor

* `otel.bsp.schedule.delay=5000`
* `otel.bsp.max.queue.size=2048`
* `otel.bsp.max.export.batch.size=512`
* `otel.bsp.export.timeout=30000`

### Meter provider

<Info>
  The following configuration options are specific to `SdkMeterProvider`.
</Info>

* `otel.metric.export.interval=60000`
* `otel.metric.export.timeout=10000`

### Logger provider

<Info>
  The following configuration options are specific to `SdkLoggerProvider`.
</Info>

* `otel.blrp.schedule.delay=1000`

* `otel.instrumentation.common.experimental.view-telemetry.enabled=true`
* `otel.instrumentation.common.default-enabled=false`

<Info>
  Disable all auto instrumentation and enable only what's necessary. This has to be commented out entirely to work as default.
</Info>

### Disable annotated methods

* `otel.instrumentation.opentelemetry-instrumentation-annotations.exclude-methods=my.package.MyClass1[method1,method2];my.package.MyClass2[method3]`

### Instrumentation config per library
