2 fmMonitor fmMonitor Manages frame monitor configuration.

This command supports predefined and user-defined names for frame types defined by their offset, bit mask, and frame values. For each frame type you can configure a threshold and specify one or more alert mechanisms, such as RAS log, SNMP trap and email. Frame monitors count the number of frames transmitted through a port that match specific values in the first 64 bytes of the frame. Because the entire Fibre Channel frame header and many upper protocol (for example, SCSI) headers fall within the first 64 bytes of a frame, frame monitors can detect different types of traffic transmitted through a port. Each frame monitor keeps a timestamp of its last refresh. It also keeps a generation count, which is incremented each time the monitor is cleared. Frame monitors generate alerts whenever the frame count for a certain frame type crosses the threshold configured for that frame type. You can configure high thresholds for every frame type, specify actions to be taken when the threshold is exceeded, and configure how often the data are sampled. When you create a new frame type without specifying the events, a generic filter monitor configuration for generating events is applied. The fmMonitor command supports basic Fabric Watch configurations for frame monitors. Use thConfig with the FILTER class for more advanced configurations. When you create, add, or delete a monitor, the changes are saved persistently by default. Use the -nosave option with --create, --addmonitor, and --delmonitor to override the default behavior. The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for details. The number of monitors supported per port is platform-specific. Refer to the Fabric OS Administrator's Guide for more information. 390 Fabric OS Command Reference 53-1002746-01
