Suggestions to monitor Adabas/Natural in Unix

One of our very important customers is thinking to migrate Natural/Adabas applications from Mainframe to Unix.
Currently they are using Review to monitor his environment in Mainframe and they would like to know what is our recommendation to monitor the new environment because Review is not available in that platform.

Can they get Natural program and library name using Uex4 and UexA and B in Unix ?

I’ll wait your suggestions.
Thanks and regards,
