PFLogentry

Instead of creating a complete program to analyze the PFSense(tm) log files I found it more convenient for my needs to create a small library of objects able to interpret the log entries and from there allow the manipulation of this data. This is not a generic library and has not been tested in environments other than the one used in its development.

PFLogentry was coded entirely in C++.
As I consider QtCreator(tm) to be an excellent development environment,
I use it for my projects, even if these don't directly involve using the Qt(tm) tools.

Dependencies for Compilation:

• At least C++17.
  
• Boost
  
• tinyxml2-7.0.1

My Environment

• Fedora 35
  
• clang (clang++) version 13.0.0
  
• g++ (GCC) 11.2.1 20220127 (Red Hat 11.2.1-9)
  (Under Oracle Linux 8 install gcc-devtool-10 or 8.5 install gcc-devtool-11)
  
• cmake version 3.22.0
  
• QtCreator 6.0.x (Code Style: clang-format -style=Mozilla)

Basic Operations

• Loads entire log file into memory;
• Check that the log entries are with the correct format;
• Allows counting of log entries given a condition.
  For example:
  cnt->count(PFLogentry::HdrDay).betweenAND(20,30);
  Returns the total of entries read that are between the 20th and the 30th inclusive.
• Allows query of log entries given a condition.
  
• Allows the summarization of information from log entries generating reports.
  
• Allows export of log entries to a XML file format.
