Displaying Filter-Based Monitors - HP StorageWorks MSA 2/8 - SAN Switch User Manual

Using Advanced Performance Monitoring
The hardware can manage only a limited number of unique offsets and values. If
the switch does not have enough resources to create a given filter, then other filters
may have to be deleted to free up resources.
Example 1. This command adds a filter-based monitor to count all FCP and IP
frames received from domain 0x02 for port 2.
The FCP and IP protocols are selected by monitoring offset 12, mask 0xff, and
matching values of 0x05 or 0x08. Domain 2 is selected by monitoring offset 9,
mask 0xff, and matching a value of 0x02.
The monitor counter is incremented for all incoming frames where byte 9 is 0x02
and byte 12 is 0x05 or 0x08.
Example 2. The following command adds a special case filter-based monitor for
SOFi3 on slot 1, port 2.

Displaying Filter-Based Monitors

Use the perfShowFilterMonitor command to display all of the filter-based
monitors on a specified port. You can display a cumulative count of the traffic
detected by the monitors, or you can display a snapshot of the traffic at specified
intervals.
Note:
25, etc., because registers are scanned every 5 seconds.
