Project settings - general

This page provides some general project options.

Packet buffer size

By default the packet buffer size is 16384 KB. You may change the value, but you must take the size of your system memory into account, because captured data is stored in the packet buffer and, when you save a project, the data contained in it will be saved to your hard disk.

The size you set will also affect the packet list view. The bigger size you set, the more packets you can see in the packet list view.

When buffer is full

When the number of captured packets reaches the the packet buffer size you have specified, Javvin Packet Analyzer will do one of the following:

• Discard oldest packets (ring buffer)
  It is recommended to discard the oldest packets when the packet buffer is full, Javvin Packet Analyzer will store new packets and keep the packet buffer up to date.
• Discard new packets
  All new captured packets will be discarded after being analyzed and will not be saved to the packet buffer.
• Discard all old packets
  Javvin Packet Analyzer will empty the packet buffer and then append new packets to it.
• Stop capture
  Javvin Packet Analyzer will stop capturing new packets.

Note: Don't choose this option if you would not like to cease capture.

Auto save packet file

If checked, Javvin Packet Analyzer will automatically save packets to a single file or split files as you define.

• Single file
  All packets are saved to a same file.
• Multiple files
  Packets are saved to the files split by time or size. To reduce the total size, you may choose to only keep the most recent files.
  

Statistics Settings

You can save system resources if uncheck the following statistics options.

• Enable detail protocol statistics of each endpoint.
  If uncheck this option, you will not see detail protocol statistic information of endpoints (except root nodes).
• Enable detail statistics of packet size.
  If uncheck this option (by default), you will not see the statistics of Most Common Packet Sizes in the Summary view.
  

Enable custom port

Check this option if you want Capsa to monitor non-standard ports, and then click the button  to add ports.

Always show project settings when start capture

If checked, Javvin Packet Analyzer will always open the Project Settings dialog every time when you start a new
