The TRFA resource allows to save and analyze the traffic for one or more IP interfaces.
Follow the steps described in Section 69.19, “IP traffic”.
The TRFA starting page will be shown.
Definition of the configurable parameters:
PeriodIt allows the definition of the time period that will be used as a report base.
Current year
If you select the current year, you can define the report period more precisely:
Year: the minimal period is one day.
Month: the minimal period is two hours.
Week: the minimal period is 30 minutes (half an hour).
Day: the minimal period is five minutes.
Range: You can choose the range that will be used as a report base.
Window displayA window where you can choose the time period: day/week/month/year.
Sliding: views the whole period preceding the current time and date. For instance: if you select the “day” period and the current time is 10.PM, you will get a report of the last 24 hours: until 10PM of the preceding day.
Beginning: views the period starting from the beginning of the current day: For instance, it's 9.PM, and you select the “day” period you will view the report starting at 0.AM and ending at 9.PM.
Show asIt detects an output view of the report.
Picture: in this case traffic information will be represented as a picture.
Table: in this case the traffic information will be represented as a table.
![[Note]](../images/note.png) | Note |
|---|---|
You can always switch to another view: graph/table and vice versa. To switch from graph to table, click on the graph; to switch from table to graph, click on Switch to PICTURE view. |
∑If is selected the traffic information will be represented in a unique graph.
Measure UnitsDefines the kilobytes size that will be used for the report. You can use, if you prefer, a value equal to 1000 bytes as 1024 bytes.
ThroughputThis parameter defines the unit that will be used to show the traffic information. You can select: bits per second (Bits/Sec) or bytes per second (Bytes/Sec).
IP ResourceFilters the traffic information for a selected period by IP resource only.
IP AddressFilters the traffic information for a selected period by selected IP addresses (or IP addresses intervals) only.
ProtocolsFilters the traffic information for a selected period by selected protocols only.
ReportThis button generates the graphs or the table.
ResetRestores the default settings.
TOP 10 IPShows the ten IP addresses that have generated the most traffic on an IP resource and the amount of traffic. It simultaneously generates IN, OUT, IN+OUT traffic.
TOP 20 IPShows the twenty IP addresses that have generated the most traffic on an IP resource and the amount of traffic. It simultaneously generates IN, OUT, IN+OUT traffic.
Real time analalysisIt displays the analysis in real time.
Side: Side for the analysis.
LOCAL = analyse destination IP
address in output packets and source IP in input
packets.
REMOTE = analyse source IP
address in output packets and destination IP address in
input packets, applying address translation if packets
have been natted to/from the remote IP resource.
Time window: The amount of time to consider to get an average result.
Sample interval: Sampling interval.
Reverse: Track peers of the IP address specified in Monitored IP.
Monitored IP: IP address for which peers are tracked.
Max IP addresses: Maximum number of IPs displayed.
Max graphs: Maximum number of graphs displayed.
Below there are examples of IP Traffic Analyzer consultations through HTTP interface.
Example of view: IP-1 and IP-2 resources day graphs.
In Period click day option.
Select IP-1 and IP-2 in the IP resource list (Click on IP-1 and keep the Ctrl button pressed while clicking on IP-2).
Keep the other default settings: Window display Sliding, Display information as Picture, Report type Individuals:
To view the graphs, click on the button.
| Note |
|---|---|
If the graph is grey, then in the period the TRFA wasn't activated. |
To view the tables, click on the graph.
View example: IP-2 resource day graph generated by the IP 192.168.0.33.
In Period select Day option.
Select IP-2 in the IP resource list.
Select Selected IP in the IP address filter.
Type the IP address 92.115.254.190 in the label.
Keep the other default settings: Window display Sliding, Display information as Picture, Report type Individuals.
To view the graph, click on the button.
To view the table, click on the graph.
Let’s try to view: the 10 IP addresses that have generated the most traffic on the IP-2 resource, and quantity of traffic:
In Period select Day option.
Select IP-2 in the IP-resource list.
Keep the other default settings: Window display Sliding, Display information as Picture, Report type Individuals.
To view the graph, click on the button.
| Note |
|---|---|
You can get this view only if you select one IP resource from the IP resource list at a time. |
To view the table and the whole traffic of the single IP, click on the graph.
![[Caution]](../images/caution.png) | Caution |
|---|---|
To make this view work, you must configure the TRFA on
the IP resource in
|
To view the day traffic of HTTP conveyed through the IP-1 resource, follow these instructions:
In Period select Day option.
Select IP-2 in the IP-resource list.
Select ICMP in the Protocols list.
Keep the other default settings: Window display Sliding, Display information as Picture, Report type Individuals.
To view the graph, click on the button.
To get the table view, click on the graph.
| Caution |
|---|---|
To make this view work, you must configure the TRFA on

|
To view the network traffic in real time use the Real time analisys.
Example: view who is generating more traffic on IP-2 and where the data are sent.
Select Real time analysis.
Select IP-2 resource
Keep the other default settings: Window display Sliding, Display information as Picture, Report type Individuals.
Click the TOP10 button.
We see that 92.115.254.190 is
generating more traffic than the other devices.
Select Reverse to see where the data are going to
Insert 92.15.254.190 in Monitored IP textbox
Click on TOP10 to see the IP where data is following
We see that 92.115.254.190 is
sending/receiving data from
192.168.10.254.
