## Refreshing the log file

You can view the log file for a data run in progress. In this case, you can select the ![](https://dev-assets.cms.uipath.com/assets/images/process-mining/process-mining-image-263682-a20ca0cb-bf104c50.webp) icon to refresh the log file and to reload the current status of the logs. This enables you to monitor the progress of the data run.

## Opening data transformations

You can use the **Data transformations** link to directly go to **Data transformations** to debug any errors that appear in the log.

## No logs available

:::note
When starting a data run, the log file is empty. After about 10 seconds the first log messages will be available.
:::
It can happen that there are no log files available after a failed data run. For example, when you have accidentally started a new data run that failed because the previous data run was not finished. In this case, you should **not** start a new data run, and wait for the first run to be completed. When the run is finished, the log messages of the first run will show, and the corresponding run status (run failed/success) is displayed.

## 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 |

## Filtering logs

By default, Errors, Warnings, and Information messages are displayed when you open the **Log**. You can use the **Filter** menu to change the log level. The following illustration shows an example.

## Saving the log file

You can select the ![Copy](https://dev-assets.cms.uipath.com/assets/images/process-mining/process-mining-copy-263784-77ad7744-0fafd0b6.webp) icon to copy the contents of the log file and paste in, for example, a Notepad file that you can save on your computer. This enables you to view the messages when working on solving the issues causing errors or warnings.

:::note
This also enables you to share the contents of the log file, for example if you need support.
