Logs

The logs in Javvin Packet Analyzer can record global or scope-specific network events, containing four types of log primarily generated by the advanced analyzers: HTTP requests, email messages, FTP transfers and DNS analysis. Javvin Packet Analyzer enables all logs by default, you can change each log's settings in the Project Settings - Log page. If a log is disabled, you will not see the results in the Logs view.

• HTTP Requests view - presents the information of captured web accesses. You can open a URL with double clicks on it or use the Open command from the context menu.
  
• Email Messages view - lists captured emails and such information as client, server, sender name, receiver name, etc.... To view the reconstructed contents of email, just double click the selection to open it with your email client, or use the Open command from the context menu.
  Note: Captured emails may contain virus, please be cautious when you open an email.
  
• FTP Transfers view - offers the records of FTP uploads and downloads.
• DNS Analysis view – presents the analysis results of DNS requests and replies.

Generating log files

To generate log files, you should first enable the log file feature. Open the Log page by clicking the icon  in the toolbar, select a type on the left, then enable the selected log file on the right. Click the button  to open the Log File Settings dialog, where you can name the log file and designate file path. Javvin Packet Analyzer will automatically generate log files if you check Multiple files and set the parameters; you may also customize the count of log files saved in your system.

Log file formats

Javvin Packet Analyzer generates HTTP, email, FTP or DNS log files only when these logs are enabled in the Project Settings - Log page, where you can designate analysis ports, set filters, select log location or customize other options. The format of log files is: name%year-%month-%day hour.minute.second.log. For example, a log generated on August 18th, 2005 09:25:23 AM with the base file name "http" is shown as http2005-08-18 09.25.23.log.

Logs can be saved to a single file or split files. If you select split files, Javvin Packet Analyzer will automatically split log files by month, day, hour, minute, KB or MB.
