To display the top flows on domain 2 in PID format: perfttmon --show dom 2 pid switch:admin> perfttmon --show dom 2 pid Src_PID Dst_PID MB/sec 0xa908ef 0xa05200 6.926 0xa05200 0xa908ef 6.872 0xa905ef 0xa05200 6.830 0xa909d5 0xa05200 6.772 Limitations of Top Talker monitors Note the following when using Top Talker monitors: • Top Talker monitors cannot detect transient surges in traffic through a given flow. • You cannot install a Top Talker monitor on a mirrored port. • Top Talker can monitor only 10,000 flows at a time. • Top Talker is not supported on VE_Ports, EX_Ports, and VEX_Ports. Trunk monitoring To monitor E_Port (ISL) and F_Port trunks, you can set monitors only on the master port of the trunk. If the master changes, the monitor automatically moves to the new master port. If a monitor is installed on a port that later becomes a slave port when a trunk comes up, the monitor automatically moves to the master port of the trunk. Note the following: • For Fabric OS 3.x switches, monitoring can be set on slave ISLs. • End-to-end monitors are not supported for ISLs. • For F_Port trunks, end-to-end masks are allowed only on the F_Port trunk master. Unlike the monitors, if the master changes, the mask does not automatically move to the new master port. • 4/8 SAN Switch, 4/16 SAN Switch, 8/8 SAN Switch, 8/24 SAN Switch models support eight filter-based monitors for trunks. • The SAN Switch 4/32, 4/64 SAN Switch, SAN Switch 4/32B, 8/40 SAN Switch, 8/80 SAN Switch, 400 Multi-protocol Router, 4/256 SAN Director and DC Director switches support 12 filter-based monitors for trunks. Displaying monitor counters You can display the monitors on a specified port. For end-to-end counters, you can display either the cumulative count of the traffic detected by the monitors or a snapshot of the traffic at specified intervals. To display monitor counters: 1. Connect to the switch and log in as admin. 2. Issue the perfmonitorshow command: perfmonitorshow --class monitor_class [slotnumber/]portnumber [interval] where: • monitor_class is the monitor class, which can be one of EE (end-to-end), FLT (filter-based), or ISL (inter-switch link). The -- --class monitor_class operand is required. • slotnumber specifies the slot number for a 4/256 SAN Director director. For all other switches, this operand is not required. The slot number must be followed by a slash ( / ) and the port number, so that each port is represented by both slot number (1 through 4 or 7 through 10) and port number (0 through 15).
