You can install AppMon Java Agents to monitor business transactions that use either the CICS Transaction Gateway or the IMS Soap Gateway.
Have a look on the below link for the Mainframe environments.
We dont have CICS or IMS Soap Gateway. We have been using Appmon on WebSphere for z/os for some time to monitor java web applications. What I want to ask is that z/os 2.3 version [new] is compatible with current product or not. And if so which versions of AppMon specifically?
From the link you shared I see that; z/os 2.3 is in the list of supported "Mainframe Environments" however, it is not on supported "Platforms and Operating Systems"
So for WebSphere for z/os what is the supported operating system version on mainframe?
