# How to generate HAR file and console log when facing console issues?

Last updated: July 24, 2026

This guide explains how to generate and submit HAR files and console logs to troubleshoot MDM web console issues such as slow loading or page rendering problems, with instructions for Chrome, Firefox, Internet Explorer, Microsoft Edge, and Safari. Since HAR files can contain sensitive data like cookies and submitted form details, it's recommended to log out and back in after capturing logs, and both HAR logs and console logs should be provided for accurate analysis.

## Description

When you are facing issues with MDM web console, you might be required to generate HAR (HTTP Archive) files which will help in identifying performance issues such as slow loading time and page rendering problems. Collect and upload the HAR log from the machine using which you are trying to connect to web console, for analyzing browser console logs and resolving the UI issues.

**Note: To ensure the security of your data, please be aware that HAR files may contain sensitive information. We recommend logging out and then logging back into the product console after capturing and sending us the HAR logs.**

The following types of data may be included in the HAR file:

- The content of the pages accessed during the recorded session.
- Cookies, which may contain personally identifiable information.
- Any data submitted while recording, such as personal details, passwords, and credit card numbers.

**Note: It is important to provide both [HAR logs](https://www.manageengine.com/mobile-device-management/how-to/mdm-upload-har-log.html#generating-har-file) and [console logs](https://www.manageengine.com/mobile-device-management/how-to/mdm-upload-har-log.html#enabling-timestamps) for accurate troubleshooting and analysis.**
