From the Nodes section, details of all physical nodes (in other words running gateway instances) that belong to the logical gateway can be visualized. From this page, details of the physical host URL where the gateways are running are visible. If the host URLs are to be accessed via HTTP proxies, the proxies' URLs can be specified from this page.
Of special interest, is the polling intervals information which is available on the top-right-hand side of the section.
