# FAQ

## Data Display

### Why do I not see any CPU data or Active Processes?

- Check Device Events to see if sipagent.exe is being blocked by one of your security products. To solve the problem, make sure you perform the necessary whitelisting described in the [prerequisites article](/v1/docs/prerequisites-for-agent-deployment).

### Why is the Active Processes grid empty?

- The device has been offline for more than 10 minutes.
- The device has only just come online and has not yet sent its first update. Wait 20-30 seconds. If you have WebSockets working on the device you should see Active Processes in about 10 seconds.

### Why do I not see some processes in the CPU Usage widget?

- The only processes which are displayed in the CPU Usage widget are those which consume more than 5% of available CPU and RAM resources, over a 60-second sample period.
- CPU Usage values are the average usage over the 60-second sample period. For example, if a process uses 100% for 6 seconds and then goes back to idle, the CPU Usage value for the 60-second sample window is 10%.
- The machine OS does not allow queries of some highly secure OS components, or if a large amount ofCPU and RAM resources is taken by System Interrupts.
- For Mac and Linux: Only processes running at the time the sample is taken are captured, so if a process stops before the end of the 60-second sample window, the system is unaware of it.
- For Windows, processes which stopped during the 60-second sample window are captured and displayed.

## General

### How do I set a proxy by system level environment variable?

The Agent installation documentation shows you how to set a proxy during installation. For all platforms, you can also set up a system-level environment variable called HTTPS_PROXY, and then restart the Agent and Agent Manager. See [HttpClient.DefaultProxy Property (System.Net.Http)](https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclient.defaultproxy?view=net-5.0).

### How much network traffic does an agent send each day?

- The amount of data uploaded by an agent each day can vary widely, depending on both the extent of end-user activity, as well as the configuration of what end-user activity is collected (e.g., app foreground and URL activity, process whitelist, etc.)
- A rough estimate is between 5MB uploaded per device per day, up to as much as 20MB for a device that is being used around the clock.

### What are "SIP", "AI", and "CPE"?

- These are acronyms for previous product names that may still appear in some places.

### I'm running a Command from Actions in the Device page, but nothing is happening.

- This just starts a process with arguments, it is not a command prompt. For example, if you want to use mkdir (which is not a binary or exe) you have to use “cmd /c=mkdir %temp%\hello”.
- Commands run as System, so processes start in the background, don't run in the user session, and have no access to a desktop.

### How does ControlUp for Desktops use WebSockets?

- Each device attempts to connect to the tenant using a WebSocket. This is a long-running connection, initiated by the device (still outbound 443 HTTPS), which allows the tenant to send actions and scripts instantly to the agent.
- Some proxies do not allow WebSockets, and they also cannot be established on mobile hotspots. In these cases, the agent reverts to polling every 15 seconds.
