# Server CPU Usage Displays ERR

### **Issue**

Some servers display ERR in the **CPU**, **Disk Queue**, **Avg. Disk Read** and **Write Time** fields. ![CPCPU, Disk Queue, Avg. Disk Read and Write Time fields](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/mceclip0(2).png)

### **Reason**

This issue might happen due to corrupted WMI/performance counters on the target machine.

### **Solution**

Try to run a `lodctr /r` command on the problematic server and then restart the ControlUp agent.

If that doesn't work, you might need to salvage the WMI repository by opening CMD and running the `winmgmt /salvagerepository` command. Then restart the server.

To test the ability to retrieve performance data outside of ControlUp, you can use PowerShell commands, for example:

```powershell
Get-Counter –ComputerName WIN7MED7 -Counter "\Processor(_Total)\% Processor Time"

Get-Counter -Counter "\Processor(_Total)\% Processor Time"
```

If you still have an issue, check the regional settings of the OS, and see under Copy Settings if all properties are of the same language. If not, ERR will be shown. ![regional settings of the OS dialog box](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/2017-07-03_1245.png)
