Use the perfhelp command to display a list of commands associated with Advanced Performance Monitoring. For detailed information on these commands, see the Fabric OS Command Reference. NOTE: The command examples in this chapter use the slot/port syntax required by the following: • HP StorageWorks 4/256 SAN Director • HP StorageWorks DC SAN Backbone Director • HP StorageWorks DC04 SAN Director Switch platforms. For the following, use only the port number where needed in the commands: • HP StorageWorks 4/8 and 4/16 SAN Switches • HP StorageWorks 8/8 and 8/24 SAN Switches • HP StorageWorks SAN Switch 4/32 • HP StorageWorks 4/64 SAN Switch • HP StorageWorks SAN Switch 4/32B • HP StorageWorks 8/40 SAN Switch • HP StorageWorks 8/80 SAN Switch • HP StorageWorks 400 Multi-Protocol Router End-to-end performance monitoring End-to-end performance monitoring counts the number of words in Fibre Channel frames for a specified Source ID (SID) and Destination ID (DID) pair. An end-to-end performance monitor includes these counts: • RX_COUNT (words in frames received at the port) • TX_COUNT (words in frames transmitted from the port) To enable end-to-end performance monitoring, you must configure an end-to-end monitor on a port, specifying the SID-DID pair (in hexadecimal). The monitor counts only those frames with matching the SID and DID. Each SID or DID has the following three fields. • Domain ID (DD) • Area ID (AA) • AL_PA (PP) For example, the SID 0x118a0f denotes DD 0x11, AA 0x8a, and AL_PA 0x0f. 406 Administering advanced performance monitoring
