[lime-users] Internet gateways - configuring and monitoring

Hi, What are the LibreMesh criteria for Internet gateway selection? How do its metrics work? I mean for Expansive Emancipation. How do you check the Internet gateway used by each node? If I don't like the Internet gateway a node automatically chooses, how could I tune it to affect its decision? Do you have any suggestion for a centralized tool (preferably with alerts) to monitor the Internet gateways used by each node and their status? Thank you!
