Analysis

You can perform detailed analysis of flow data on the Analysis page.

The page is divided into three parts: The upper part is for viewing flow data and for selecting a time slot or window. The middle part shows a graph legend and allows you to switch the particular channels and NPM (network performance metrics) on and off.

The button Change displayed channels opens a selection form for adding and removing channels from the graph and legend. The checkbox Show 3 Week Average line adds a new line to the chart that shows the average volume of the traffic that was collected on the same day and time in the previous 3 weeks. The checkbox Show new channels automatically in this form enables the automatic addition of new channels (for example, newly detected flow sources are automatically added to the All Sources graph). The checkbox Show NPM statistics adds a new y-axis to the detailed graph and three new line graphs for the following network performance metrics provided by Flowmon Probes: Traffic Jitter, Round Trip Time, and Server response time.

The button Get channels statistics opens a table containing information about the selected time window.

You can choose from charts displaying the number of flows (Flows), number of packets (Packets), and number of transferred bits (Traffic). When you click one of the small charts, it is swapped with the main chart. You can choose the most suitable chart for your situation/investigation.

In addition to profiles version 1, data can be filtered according to the network protocols - All, TCP, UDP, ICMP, and Other. Note: All means all data without filtering and Other means protocols other than TCP, UDP, and ICMP. This feature is not available for 1-min and 30-sec profiles.

The time slot shown in the charts can be set either using the Interval combo box above the charts or by the manual setting of start (From) and end (To) time next to the combo box. If you set the range manually, you must confirm your choice by clicking Set Interval. The minimum time interval is 6 hours.
