Each Orchids module may propose a set of configuration options. To specify options to module module-name, write <module module-name>, followed by options specific to module-name, one per line, and end them by </module>.
By convention, all this should be written in a file named nn_mod_module-name.conf in the $OCONF/conf.d directory. This file will be loaded by the Include @@ETCDIR@@/orchids/conf.d/*.conf directive in orchids.conf.dist, in standard distributions. The two-digit number nn is arbitrary, and is meant to force the order in which modules are loaded from the $OCONF/conf.d directory.
For example, the first module whose configuration is loaded is (typically) textfile. So you may find the following lines in $OCONF/conf.d/01_mod_textfile.conf:
<module textfile> PollPeriod 15 # INPUT "/var/log/messages" # ProcessAll 1 # ExitAfterProcessAll 1 </module>
As usual, the sharp sign # is used to start comments.
Module-specific options are documented on the page of the corresponding module.
