The BEA Guardian Log Files contain information that is typically only needed by BEA in the unlikely event of an exception. One situation where you may want to view a log file is running command line scripts and automatically scanning the signature.log for detected signatures.
The Guardian log files are:
guardian.log - located in the guardian installation directory you specified during installation. Contains information about every operation the Guardian application performs.
signature.log - located in the guardian installation directory you specified during installation. Contains information about each evaluation performed.
.log - located in the .metadata subdirectory of the Guardian Workspace directory you specified when starting Guardian. Contains information about certain Guardian operations.
install.log - located in the configuration/org.eclipse.update subdirectory of the Guardian installation directory you specified during installation. Contains information about the Guardian installation itself.
