## Log levels

The log contains different *log levels* to indicate the severity of the message:

| **Log level** | **Description** | **Data run status** |
| --- | --- | --- |
| Information | An **Information** message contains helpful information on the progress of the datarun. | Success |
| Warning | A **Warning** refers to a potential problem in your data that might affect what will be displayed on a chart in the published process app. It is advised to resolve any warnings to prevent any potential future problems. | Success |
| Error | An **Error** refers to a mistake in your data that prevents the process app from loading the data or running the transformations. You must resolve all errors to enable a successful data run. | Failed |
