Wireshark provides a wide range of network statistics.
These statistics range from general information about the loaded capture file (like the number of captured packets), to statistics about specific protocols (e.g. statistics about the number of HTTP requests and responses captured).
You will find some information about statistics in the corresponding User's Guide chapter(s).
Summary about the capture file like: packet counts, captured time period, ...
Protocol Hierarchy of the captured packets.
Conversations e.g. traffic between specific Ethernet/IP/... addresses.
Endpoints e.g. traffic to and from an Ethernet/IP/... address.
IO Graphs visualizing the number of packets (or similar) in time.
Protocol specific statistics
Service Response Time between request and response of some protocols.
TcpPduTime The time it took to transfer all segments of a PDU spanning multiple segments, great for finding TCP Retransmissions.
VoIP_calls Get the VoIP calls from the capture. The current VoIP supported protocols are SIP, H323, ISUP and MGCP with their corresponded RTP traffic. The calls can also be Graph and filtered for analysis.
Various other protocol specific statistics.
