A system for controlled-tuning path performance data collection through a single application control. In an embodiment, performance data collection may be turned on or off from an application host running a path performance data application via a user interface. The tool may automatically update performance data collection characteristics as the application host I/O data path changes according to user controlled settings but without requiring further user intervention during the updating. In various embodiments, the tool may update continuously and/or at specified intervals. Turning on path performance data collection on the application host via the user interface may automatically set up synchronized performance data collection for all managed objects within I/O data path(s) of the managed objects.

Path performance data collection

A method and apparatus for identifying devices on a network. A management device is configured to multicast a query message to request identification of network devices. Each of the network devices is configured to respond to the management device multicast message by transmitting a reply message containing identification information of the responding device. The management device includes a directory containing the identification information of the network devices. The network protocol can include the TCP/IP protocol, and the packets have a format complying with a bootstrap protocol.
