# No Historical Data: Clearing the Monitor Chain

## Problem

A corrupt monitor chain might be the cause that you don't see historical data in the VDI App. If this is the case, follow the instructions below to receive historical data again. ![VDI App showing CPU Usage widget](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/image-FOR4RDI9.png)

Make sure to restart all monitor services before proceeding with the solution, as sometimes the historical data will be uploaded again after a restart.

## Solution

          Important

          

It is important that you perform these steps on each ControlUp Monitor machine in your environment.

1. Remotely connect to the monitor machine.
2. Search for **services.msc** in the Start Menu search box.
3. Stop the Monitor service. Right-click **ControlUp Monitor** and click **Stop**. Wait until the service is stopped.

4. Open regedit by typing **regedit.exe** in the Start menu.
5. Navigate to `HKEY_USERS\S-1-5-20\Software\Smart-X\ControlUp\HistoricalReportingPackages` and delete the key under **HistoricalReportingPackages**.

6. Open the Windows Explorer and browse to  `C:\Windows\ServiceProfiles\NetworkService\AppData\Roaming\ControlUp\CacheActivity`. Delete the key that has the same GUID as the one you deleted in the Registry.

7. Verify again that both the key in the Registry and the folder on the file system are deleted.
8. Start the Monitor service again.
