Fake Log Generator

Motivation

Visor provides a fake log generator to generate likely log files for analysis. If no real world logs can be found right now, it would be a good substitute for testing the monitor.

Usage

$python3.4 $Visor_HOME/src/fake_log_gen/fake_log_gen.py -m pattern -o outputfile

The outputfile parameter set the path and name of the output file, and pattern set the desired output log pattern. The details of available log patterns can be found in chapter Log Pattern.

Examples

If we run the command:

$python3.4 $Visor_HOME/src/fake_log_gen/fake_log_gen.py -m access -o fake_access_file.log

The we can get outputs in fake_access_file.log like:

- - - [28/Dec/2016:16:55:53 -0700] "HEARBEAT" - -

This is the result of simulating Apache access logs. All the fields and the intervals can be configured.
