.config to create tricks?

I am working on a quick project to monitor / process data. In fact, these are just monitors, graphics, and processors. The monitor checks the data (ftp, local, imap, pop, etc.) using a schedule and sends new data to the processor. All of them have interfaces.

I am trying to find a reasonable way to use config to configure the graph / processor that each monitor uses. This is pretty easy:

<monitor type="any.class.implementing.monitor">
    <schedule type="any.class.implementing.schedule">
        ...
    </schedule>
    <processor type="any.class.implementing.processor" />
</monitor>

What I'm struggling with is the best way to set up any old monitor / graph / processor thrown into a mix. On the one hand, it was possible to implement constructor parameters or properties (let's take any syntax):

<monitor type="any.class.implementing.monitor">
    <args>
        <arg value="..." />
    </args>
    <properties>
        <property name="..." value=..." />
    </properties>
    <schedule type="any.class.implementing.schedule">
        ...
    </schedule>
    <processor type="any.class.implementing.processor" />
</monitor>

Another solution is the factory method in each interface, which takes the user configuration as a parameter:

public IMonitor Create(CustomConfigSection config);
