Composite monitors

[mnaboka]

hello, this looks like an interesting project, i was wondering if it was possible to create composite monitors with this tool?
I am not sure what would be the best way to represent a dependency graph of monitors something like this:

                                +-----------------+
                           +----+composite monitor+---+
                           |    +-----------------+   |
                           |                          |
                           |                          |
                     +-----v-----------+     +--------v--+
                   +-+composite monitor+--+  |query alert|
                   | +-----------------+  |  +-----------+
                   |                      |
                   |                      |
         +---------v-------+       +------v----+
      +--+composite monitor+--+    |query alert|
      |  +-----------------+  |    +-----------+
      |                       |
      |                       |
+-----v-----+         +-------v---+
|query alert|         |query alert|
+-----------+         +-----------+
