=head1 LOGGING |
948 |
|
|
949 |
|
Logging in WebPAC is performed by L<Log::Log4perl> with config file |
950 |
|
C<log.conf>. |
951 |
|
|
952 |
|
Methods defined above have different levels of logging, so |
953 |
|
it's descriptions will be useful to turn (mostry B<debug> logging) on |
954 |
|
or off to see why WabPAC isn't perforing as you expect it (it might even |
955 |
|
be a bug!). |
956 |
|
|
957 |
|
B<This is different from normal Log4perl behaviour>. To repeat, you can |
958 |
|
also use method names, and not only classes (which are just few) |
959 |
|
to filter logging. |
