Using Advanced Performance Monitoring {offset, value 0[, value 1, ..., value 3]} A B In the previous example, offset (A) is the byte offset value in the header of the FC frame and value 0[, value 1, ..., value 3] (B) is a user-defined value, or a set of user-defined values. At least one value must be specified (value 0), but you can specify up to four values. For a filter to be matched, all the elements specified in the filter must provide a match. For an element to produce a match, the value at offset (A) in the frame being transmitted must match at least one of the user-defined values (B). The range of offsets that can be matched using filters is 0 to 63. Examples of FC Frame statistics that can be measured using filters are: ■ SCSI Read, Write, or Read/Write commands ■ IP versus SCSI traffic comparison 36 Advanced Performance Monitoring Version 3.1.x/4.1.x User Guide
