How to use the ini file
The following example was provided from https://sourceforge.net/users/pmdw/.
When using the Simple Configuration options in the log4cpp.init file this may help users configuring the log file
Command syntax as follows:
Each command is on entire line and is case sensitive <command> <category name> <layout type> <appender commands> <layout patterns>
<command>
valid commands are
- appender
- priority
- category
<category name>
valid category name are
- root
- <user defined category in application>
<layout type>
valid layout types are
- basic
- simple
- pattern
<appender commands>
valid appender commands are
- file <followed by a log file name>
- rolling <followed by a log file name> <the max size of the file> <and the max number of files to keep>
- console
- stdout
- stderr
- nteventlog <category name>
- syslog <category name>
- remotesyslog <category name>
<layout patterns>
The simple layout follows this pattern
%p - %m%n
The basic layout follows this pattern
%R %p %c %x: %m%n
Valid commands for pattern layout.
all commands for pattern are prefixed with %
all commands for pattern are case sensative
- %n = create new line ( this is usually at the end to make a new line break
- %m = Place the message here
- %c = Place the category name here
- %d = Place the date time stamp here
- %p = Place the message priority here
- %t = Place the thread name here
- %u = Place the processing time component here.
- %x = Place the Nested Diagnostic Context (NDC) here.
NDC is an instrument to distinguish interleaved log output from different sources.
