# OpenTelemetry Agent Without Auto Init | Sentry for Spring Boot

You may also disable automatic initialization of Sentry in `sentry-opentelemetry-agent` by setting `SENTRY_AUTO_INIT=false` as an environment variable. Doing this will mean you'll either have to use another Sentry integration that performs initialization, (for example Spring Boot), or initialize Sentry manually.

For Spring Boot we recommend disabling the Agents `AUTO_INIT` and instead letting our Spring Boot integration take care of initializing the SDK as this allows for a more convenient configuration of Sentry using `application.properties`/`application.yml` and Spring beans.

## [Install](https://docs.sentry.io/platforms/java/guides/spring-boot/opentelemetry/setup/agent/no-auto-init.md#install)

You can download the latest version of the `sentry-opentelemetry-agent-8.37.1.jar` from [MavenCentral](https://search.maven.org/artifact/io.sentry/sentry-opentelemetry-agent). It's also available as a `ZIP` containing the `JAR` used on this page on [GitHub](https://github.com/getsentry/sentry-java/releases/).

## [Usage](https://docs.sentry.io/platforms/java/guides/spring-boot/opentelemetry/setup/agent/no-auto-init.md#usage)

This `java` command shows how to run your application using `sentry-opentelemetry-agent`:

```bash
SENTRY_AUTO_INIT=false JAVA_TOOL_OPTIONS="-javaagent:sentry-opentelemetry-agent-8.37.1.jar" java -jar your-application.jar
```

The Spring Boot Sentry SDK will take care of initializing Sentry, just make sure a `tracesSampleRate` has been set:

```properties
sentry.dsn=___PUBLIC_DSN___
sentry.traces-sample-rate=1.0
```

## [Debugging](https://docs.sentry.io/platforms/java/guides/spring-boot/opentelemetry/setup/agent/no-auto-init.md#debugging)

To enable debug logging for Sentry, set `SENTRY_DEBUG=true` as an environment variable or add `sentry.debug=true` to your `application.properties`.

To show debug output for OpenTelemetry, add `-Dotel.javaagent.debug=true` to the `java` command.

## [Turn Off Exporter Error Messages](https://docs.sentry.io/platforms/java/guides/spring-boot/opentelemetry/setup/agent/no-auto-init.md#turn-off-exporter-error-messages)

If you're not using any OpenTelemetry exporters besides Sentry, add the following environment variables to turn off exporters and stop receiving error messages about servers not being reachable in the logs.

Example log message:

```bash
ERROR io.opentelemetry.exporter.internal.grpc.OkHttpGrpcExporter - Failed to export spans. The request could not be executed. Full error message: Failed to connect to localhost/[0:0:0:0:0:0:0:1]:4317
ERROR io.opentelemetry.exporter.internal.grpc.OkHttpGrpcExporter - Failed to export metrics. The request could not be executed. Full error message: Failed to connect to localhost/[0:0:0:0:0:0:0:1]:4317
ERROR io.opentelemetry.exporter.internal.http.HttpExporter - Failed to export logs. The request could not be executed. Full error message: Failed to connect to localhost/[0:0:0:0:0:0:0:1]:4318
```

#### [Traces](https://docs.sentry.io/platforms/java/guides/spring-boot/opentelemetry/setup/agent/no-auto-init.md#traces)

To turn off traces exporting, set `OTEL_TRACES_EXPORTER=none` as an environment variable per [OpenTelemetry GitHub](https://github.com/open-telemetry/opentelemetry-java/tree/main/sdk-extensions/autoconfigure#otlp-exporter-span-metric-and-log-exporters).

#### [Metrics](https://docs.sentry.io/platforms/java/guides/spring-boot/opentelemetry/setup/agent/no-auto-init.md#metrics)

To turn off metrics exporting, set `OTEL_METRICS_EXPORTER=none` as an environment variable per [OpenTelemetry GitHub](https://github.com/open-telemetry/opentelemetry-java/tree/main/sdk-extensions/autoconfigure#otlp-exporter-span-metric-and-log-exporters).

#### [Logs](https://docs.sentry.io/platforms/java/guides/spring-boot/opentelemetry/setup/agent/no-auto-init.md#logs)

To turn off log exporting, set `OTEL_LOGS_EXPORTER=none` as an environment variable per [OpenTelemetry GitHub](https://github.com/open-telemetry/opentelemetry-java/tree/main/sdk-extensions/autoconfigure#otlp-exporter-span-metric-and-log-exporters).
