When building Klogger with a specific set of schemata, a decoding utility is created for that specific kernel able to decode the binary log into a more human friendly, text formatted file. As mentioned earlier, the text format is basically an array of Perl Hashes, each represeting an event.
Assuming your Klogger kernel sources reside under KERN_ROOT, the decoder is compiled into
KERN_ROOT/kdecoder/klogger_decoder
This tool's operation is very simple: its only command line argument is the binary log, whose textual conversion is printed into the standard output. As such, the usual command line would look like:
KERN_ROOT/kdecoder/klogger_decoder /tmp/kernlog.dump.cpu0 > kernlog.cpu0.txt
