Frame monitors
Frame monitors count the number of times a frame with a particular pattern is transmitted by a
port and generate alerts when thresholds are crossed. Frame monitoring is achieved by defining a
filter, or frame type, for a particular purpose. The frame type can be a standard type (for example,
an SCSI read command filter that counts the number of SCSI read commands that have been
transmitted by the port) or a frame type that you can customize for a particular use. For a complete
list of the standard, pre-defined frame types, see the fmMonitor command description in the Fabric
OS Command Reference Manual.
To enable frame monitoring, you must install a frame monitor on an F_Port or N_Port in the AG
switch using the fmMonitor command. Using options in this command, you can also perform the
following tasks:
• Create a new frame type.
• Delete a specified frame type.
• Delete the set of ports on which the specified frame type can be monitored.
• Add a set of ports for which a specific frame type can be monitored.
• Save a set of ports on which the specified frame type can be monitored.
• Show different frame types configured on the switch, as well as frame counters.
• Change properties for a particular frame type, such as thresholds and bit pattern.
• Clear a set of ports on which the specified frame type is monitored to the persistent
configuration.
Complete details of the fmMonitor command parameters are provided in the Fabric OS Command
Reference Manual.
The thConfig command can be used for advanced configuration of filter thresholds corresponding
to frame monitors. See the Fabric Watch Administrator’s Guide for more information about using
this command.
