Top N Segments, Percentage of errors | HP Transcend Traffix Manager

110CHAPTER 12: REPORT TYPES

Table 14 Top N Groups Report Charts (continued)

Report	Chart Title	Description
Section	Chart Title	Description

	Long Term	A line chart showing the total octets sent and received
	Trend	by the device for as long as Traffix Manager has records.
2.1	Top Sub-Groups	A stacked bar chart showing the top 10 sub-groups
	With Protocol	within the detail group, broken down by protocol. The
	Distribution By	octet total has the same internal, external or overall
	Octets	filter as the detail group applied.
3	Report	Information about the report itself.
	Information

Top N Segments	This report calculates the top N segments by utilization, and by
Report	percentage of errors.
	For most networks it is sufficient to allow Traffix Manager to select
	automatically the top N segments by selecting All Segments for the top N
	segments report.

Since it is possible that the top N segments identified by utilization are different from the top N segments identified by percentage of errors, Section 2 of this report can contain more than N segment details. If the high error segments are completely different from the high utilization segments, you end up with 2 x N details in the details section.

Table 15 Top N Segments Report Charts

Report	Chart Title	Description
Section	Chart Title	Description

1.1	Top Segments	A bar chart containing the top N segments as measured
	By Utilization	by percentage utilization of bandwidth.
	Protocol	A pie chart showing the top 10 protocols seen across all
	Distribution Of	of the N segments. If more than 10 protocols are seen,
	Top Segments	the remainder are grouped as other.
	Protocol	A stacked bar chart showing the protocol breakdown of
	Distribution By	each of the N segments by octets. The order of the bars
	Octets	is the same as the utilization bar chart. Because
		utilization is not the same as octets, the bars in this
		chart may not always appear in descending order. For

example, the utilization on a 100Mbps Ethernet segment may be quite low compared to a 10Mbps segment, but the octet count may be considerably higher.
