The key point is that output modules never deal directly with msg objects (and
other internal structures). Besides security, this also greatly simplifies the

+<h2>Action Selectors</h2>
+<p>Modules (and rsyslog) need to know when they are called. For this, there must
+a an action identification in selector lines. There are two syntaxes: the
+single-character syntax, where a single characters identifies a module (e.g. &quot;*&quot;
+for a wall message) and the modules designator syntax, where the module name is
+given between colons (e.g. &quot;:ommysql:&quot;). The single character syntax is
+depreciated and should not be used for new plugins.</p>
+<p>An in-depth discussion of module designation in action selectors can be found
+in this forum thread:</p>
