I'm not familiar with NetFlow Analyzer, but Meraki gear doesn't have an SSH or telnet interface (at least not one meant for the public, I think there may be one for Meraki employees).
You can export Netflow from the MX. The configuration of that is at the bottom of your "Reporting" screenshot. The autoconfiguration feature of NetFlow Analyzer is not needed in that case (and it won't work). You just need to be able to configure it as a Netflow Collector. Maybe it's in the Netflow tab instead of the discovery tab.
