Synopsis

nodeInfo nodeURL

Description

The nodeInfo utility displays basic information about a node and its subnodes, including time at which the node service as last started, the node's ID, and the address of an associated network switch (e.g. Medusa) if present. Note that the switch address will only be displayed if a NetworkSwitch instrument service is currently running on the node. The subnodes list includes any subnodes that have registered with this "parent" node since its service was started. Information displayed for each subnode is described in the documentation for listSubnodes.
