### ReconcileErrors

|            |                                                                                                                                   |
| ---------: | --------------------------------------------------------------------------------------------------------------------------------- |
|    Meaning | The OpenTelemetry Operator cannot succeed in the reconciliation step, probably because of a misconfigured OpenTelemetryCollector. |
|     Impact | No impact on already running deployments or new correct ones.                                                                     |
|  Diagnosis | Check manager logs for reasons why this might happen.                                                                             |
| Mitigation | Find out which OpenTelemetryCollector is causing the errors and fix the config.                                                   |

### WorkqueueDepth

|            |                                                                                                          |
| ---------: | -------------------------------------------------------------------------------------------------------- |
|    Meaning | The working queue for the operator is larger than 0.                                                     |
|     Impact | No impact if the queue depth reverts to 0 quickly. More investigation is needed if the problem persists. |
|  Diagnosis | Check manager logs for reasons why this might happen.                                                    |
| Mitigation | This could be caused by many errors. Act based on what the logs are showing.                             |
