Click the ‘Analyze PCAP’ button to start analysis (see screenshot).Īfter less than a minute, the four million packages stored on the USB stick are analyzed. The pcap then appears in the storage overview. The file is downloaded to the Allegro Network Multimeter with a USB stick for subsequent pcap analysis. This isolation of the desired traffic or the incorrect traffic flows is achieved by the analysis modules integrated into the Allegro Network Multimeter. Therefore, you should only select the part of the traffic where the problem has been identified before analysing it in the usual way in Wireshark.

Similar times are to be expected even when a filter is used. For example, a sample file containing three million packets can be read by Wireshark in 30 seconds, whereas a slightly larger one with four million packets takes more than eleven minutes. The problem with Wireshark is that as soon as a pcap exceeds a certain size, it takes longer to analyze the packets. Finding a fault can be tedious via Wireshark.
