Hello everyone. Just wanted to ask if WLC C9800-L, when user connects to access point and got connected, is there have a feature of generating a file which shows how long the user uses that access point?

WLC does not hold data as It has no storage. In order to check this information you need to use command like

show client detail <MAC address>

The output Will show you how long the client is connected.

You can use script to run the command periodically and save the data

You may try debug for that client mac.

debug client <mac address>

If you don't need debug, if you desire to get this details for multiple clients, it's possible via Catalyst Center (DNAC) or Cisco Prime (if you already have) or use Telemetry data to build you own graphs.

I think it hard, if wifi client is roaming then when you do check in wlc it show you present AP wifi client connected to.

As the previous post say, there's no possibility on the controller itself. Two possible options are:

Python Script + API
Write a Python Script that connects to the controller's API (i.e. REST) to read the client list, filter it and output it to a file.
RADIUS Accounting
If you run a RADIUS Server, you can usually log and export the user's behaviour (logon, logoff) to a file.

As above, DNAC, Radius Accounting, Python Scripts
But you could also look at streaming telemetry using Grafana

Hello, so it is not possible to make it in GUI itself? We have to go on controllers console?

You can also go to Monitoring > Wireless > Clients and click on the "Export to Excel" button. But I don't know if that's what you're really looking for.
