Suggestion from a customer:Can there be an option to easily show all interfaces, e.g. on a network switch, regardless of connection status? (a bit like you can show/hide \'\'all associated datasources\'\' for a host)Normally active discovery will only show connected interfaces for a switch (logically, to avoid alerting on ports without connections); one customer mentioned that he has some switches that engineers will plug into, short term, for testing - so the port then appears on the host, then starts alerting shortly afterwards when disconnected. He wanted to be able to list all ports, to turn off alerting on normally-disconnected ones. We did this by removing the \'\'status = UP\'\' filter on a clone of the \'\'Interfaces (64 bit)-\'\' datasource, which allowed him to see all the ports on a switch and disable alerting on the currently disconnected ones.I pointed out this will prevent newly-connected permanent connections from generating alerts if they fail, unless he remembers to re-activate alerts, but in his situation apparently the \'\'random test connection\'\' is far more common than adding a new piece of hardware so he accepted this drawback.
