5.2 Aspect views
Traffic views are snapshots of the currently occurring traffic situation. The current traffic situation can
be viewed for configured traffic aspects, periods and various display options (for example, normal and
trend graph, pie chart, stacked or lines as well as linear or logarithmic, or Log format). The periods are
the last hour (that is, last 60 minutes), last day (that is, last 24 hours), last month (last 31 days) and so
on 1
.
Traffic volumes are given with most display options. According to IEC Standard, volumes are
provided in B (bytes), KiB (kilo binary bytes), MiB (mega binary bytes), GiB (giga binary bytes), and
TiB (tera binary bytes):
The table below shows the differences between the units used by the IEC standard and the Metric
system in traffic volume calculations.
Table 5-1 IEC Standard v Metric System
IEC Standard Metric System
1 KiB = 1024 B = 2 10
B 1 KB = 1000 bytes
1 MiB = 1024 KiB = 2 20 B
1 MB = 1000 KBs
1 GiB = 1024 MiB = 2 30 B 1 GB = 1000 MBs
1 TiB = 1024 GiB = 2 40 B
1 TB = 1000 GBs
Traffic rates are provided in b/s (bit per second), Kb/s (kilo bit per second), Mb/s (mega bit per
second) and Gb/s (giga bit per second):
1 Kb/s = 1000 b/s = 10 3 b/s
1 Mb/s = 1000 Kb/s = 10 6
b/s
1 Gb/s = 1000 Mb/s = 10 9
b/s
The user can navigate in the user interface between Overview and configured traffic aspect views with
the menu on the left side. The menu appears with the Analyzer view. Daily views aspects application,
type, and protocol are shown in Figure 5-6, Figure 5-7, and Figure 5-8.
The port view in Figure 5-9 is given in packet rates and selected top ports. That is, the remaining
difference between the stacked top ports and the total traffic usage (displayed in gray) is not shown.
Figure 5-10 shows the port view in lines mode for better visualization of the usage of individual ports.
Likewise Figure 5-13 and Figure 5-14.
Figure 5-11 and Figure 5-12 show weekly type-of-service views with all items as well as with selected
items after the y-axis was adjusted. The y-axis can be adjusted when you click Fit y-axis to scale the
view to the available data.
1 Note: This is different to the time periods used with standard reporting (see Chapter 6) which are aligned to full hours, calendar days, weeks, and so
on.
