# EDOT Collector doesn’t start
If your EDOT Collector fails to start, it's often due to configuration or environment-related issues. This guide walks you through the most common root causes and how to resolve them.

## Symptoms

EDOT Collector fails to start or crashes immediately after launch.
Possible causes include:
- Invalid YAML configuration, including syntax errors or unsupported fields
- Port binding conflicts, for example ports 4317 or 4318 already in use
- Missing or misconfigured required components, such as `receivers` or `exporters`
- Incorrect permissions or volume mounts in containerized environments


## Resolution

The solution depends on your EDOT Collector's setup:
- [Standalone](#standalone-edot-collector)
- [Kubernetes](#kubernetes-edot-collector)


### Standalone EDOT Collector

If you're deploying the EDOT Collector in a standalone configuration, try to:
- Validate configuration syntax
  Run the following to validate your configuration without starting the Collector:
  ```bash
  otelcol validate --config=/path/to/otel-collector-config.yaml
  ```
  This checks for syntax errors and missing components.
- Check logs for stack traces or component errors
  Review the Collector logs for error messages indicating configuration problems. Common examples include:
  ```
  error initializing exporter: no endpoint specified
  ```
  Most critical issues, such as missing or invalid exporters or receivers, will be logged.
  To increase verbosity, run:
  ```bash
  ./otelcol --set=service.telemetry.logs.level=debug
  ```
  This is especially helpful for diagnosing configuration parsing issues or startup errors. For more information on enabling debug logging, refer to [Enable debug logging](https://www.elastic.co/elastic/docs-builder/docs/3028/troubleshoot/ingest/opentelemetry/edot-collector/enable-debug-logging).
- Confirm required components are defined
  Ensure `service.pipelines` references valid `receivers`, `processors`, and `exporters`. The minimal configuration depends on your use case:
  - **For logs**: `filelog` receiver, `resourcedetection` processor, `elasticsearch` exporter
- **For traces**: `otlp` receiver, `elastictrace` and `elasticapm` processors, `elasticsearch` exporter
- **For managed OTLP endpoint**: use relevant receivers and export using the `otlp` exporter
  Refer to [Default configuration of the EDOT Collector (Standalone)](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/3028/reference/edot-collector/config/default-config-standalone) for full examples for each use case.
- Check for port conflicts
  By default, EDOT uses:
  - 4317 for OTLP/gRPC
- 4318 for OTLP/HTTP
  Run this to check if a port is in use:
  ```bash
  lsof -i :4317
  ```
  If needed, adjust your configuration or free up the port. For network connectivity issues, refer to [Connectivity issues](https://www.elastic.co/elastic/docs-builder/docs/3028/troubleshoot/ingest/opentelemetry/connectivity).


### Kubernetes EDOT Collector

If you're deploying the EDOT Collector using the Elastic Helm charts, try to:
- Double-check your custom `values.yaml` or -`-set` overrides for typos or missing fields.
- Ensure volume mounts are correctly defined if you're using custom configuration files.
- If you're managing the Collector through Fleet, confirm that the policy includes a valid configuration and hasn't been corrupted or partially applied.
- Use `kubectl logs <collector-pod>` to get Collector logs and diagnose startup failures.
- Check the status of the pod using:
  ```bash
  kubectl describe pod <collector-pod>
  ```
  Common issues include volume mount errors, image pull failures, or misconfigured environment variables.

If the Collector starts but no data appears in Kibana, refer to [No data visible in Kibana](https://www.elastic.co/elastic/docs-builder/docs/3028/troubleshoot/ingest/opentelemetry/no-data-in-kibana) for additional troubleshooting steps.
