Web Log Mixer 1.3

Web Log Mixer is a GUI/command line utility which helps you to combine log files generated by the web server into a single log file. Source log files can be generated either by a single web server or by different web servers in the load balancing environment. The program understands log files compressed with zip, gzip or bzip2 and can compress destination log file with gzip or bzip2.

How it works

The program is very easy to use. To start combining your log files create a configuration file and use it as a command line parameter when running the program. Also you can run the combining process from the configuration file editor. A format for running the program from the command line is:

weblogmixer.exe "configuration_file_name"

Where configuration_file_name is the full path to the Web Log Mixer configuration file like c:\logs\combine1.wlmi

Configuration file format and available options

Web Log Mixer configuration file has widely used Property=Value format. Each property-value pair shoud be placed on a separate line.

Here is the typical configuration file:

LogFormat=Auto
RemoveSource=no
Compression=gzip
AppendServerName=Yess
Overwrite=yes
ErrorLog=F:\@temp\_log_mixer_test\error.log
Silent=false
Destination=F:\@temp\_log_mixer_test\ouput\
Server=server1
Source=F:\@temp\_log_mixer_test\server1\*.log
Server=server2
Source=F:\@temp\_log_mixer_test\server2\*.log.gz

Properties for source files

Server and Source

These two properties specifies server name and corresponding source log files. The Source property should appear just after the corresponding Server definition.
