I am searching for an overview of what protocol (TCP or UDP) is used at my Citrix DAAS environment. I cannot find it in any (custom) report or not through the API. I do not have any third party monitoring tools. Maybe I am missing something or someone having an idea?

I think this is easiest way: https://docs.citrix.com/en-us/citrix-daas/hdx-transport/adaptive-transport/troubleshooting3.html ctxsession in cmd, gives a pretty good picture

Thx! I can check it on user base. But what I want is to create an overview/report for all my sessions. I do not want to check my 700+ sessions.

are they coming through a on prem netscaler gateway instead of the gateway service so go into Citrix Gateway > Monitor connections > ICA connections and it will show you if they are TCP or UDP under transport type. show vpn icaconnection via cli will show you same thing

You can get that data from the Monitor Service API via OData: https://developer-docs.citrix.com/en-us/monitor-service-odata-api/apis/#/SessionMetrics/SessionMetrics

@Jeremy Saunders Found it! Thx! Will make some time next week to sort it out. I will post my solution here! 🙂
