Using Advanced Performance Monitoring Managing Performance Monitoring with Telnet Commands Telnet commands provide three different types of performance monitoring: ■ AL_PA monitoring ■ End-to-end monitoring ■ Filter-based monitoring Note: For backward compatibility, set the environment variable FABOS_SLOTNO to a slot number. If this environment variable is set and the slot option is not specified, the value of this environment variable is used as the default slot number for the command. AL_PA Error Performance Monitoring AL_PA error performance monitoring provides information regarding the number of CRC errors in Fibre Channel frames in a loop configuration. AL_PA error performance monitoring collects CRC error counts for each AL_PA attached to a specific port. End-to-end Monitoring End-to-end monitoring provides information regarding performance between the source (SID) and destination (DID) on a fabric or a loop. Up to eight SID-DID pairs can be specified per port. For each of the SID-DID pairs, the following information is available: ■ CRC error count on the frames for the SID-DID pair ■ Fibre Channel words that have been transmitted through the port for the SID-DID pair ■ Fibre Channel words that have been received by the port for the SID-DID pair Filter-based Monitoring Filter-based monitoring provides information about a filter's hit count. All user-defined filters are matched for all Fibre Channel (FC) frames being transmitted from a port. A filter consists of a set of elements in the following format: Advanced Performance Monitoring Version 3.1.x/4.1.x User Guide 35
