We have a "rabbitmq" type for one of our custom plugins:

	rabbitmq messages:GAUGE:0:U, messages_rate:GAUGE:0:U, messages_unacknolwedged:GAUGE:0:U, messages_unacknowledged_rate:GAUGE:0:U, messages_ready:GAUGE:0:U, message_ready_rate:GAUGE:0:U, memory:GAUGE:0:U, consumers:GAUGE:0:U, publish:GAUGE:0:U, publish_rate:GAUGE:0:U, deliver_no_ack:GAUGE:0:U, deliver_no_ack_rate:GAUGE:0:U, deliver_get:GAUGE:0:U, deliver_get_rate:GAUGE:0:U 

...which seems to have 14 data sources.  I'm not sure whether that's excessive or not and I didn't write the plugin so I'm not entirely sure what it does. :)

Is there a way to raise that buffer, or do I need to re-compile to do so?  Otherwise do we need to split these types into smaller ones with less data sources (if possible)?
