What's missing is any description of how to check if Carbon has received the data correctly, what the messages in the log file mean, or even whether a piece of data has been processed by Carbon at all, or whether it has been put into a database. For that matter, maybe some description of whether Carbon has connected to the MongoDB database? Or how about some indication if the database isn't even running?

			==Hello Carbon World==

			===Start===

			First step is to start Carbon:

			<pre>
			/opt/graphite/bin/carbon-cache.py start
			</pre>

			If you see some regular expression problems, try fixing your regular expression in your storage-schemas configuration file, in the "pattern" field.

			===Log Files===

			Once you've started Carbon, take a look at the log files in

			<pre>
			/opt/graphite/storage/log/carbon-cache/
			</pre>

			===Sending Data to Carbon===

			The Graphite documentation is pathetic, but here's its description of feeding data to Carbon:

			http://graphite.readthedocs.org/en/latest/feeding-carbon.html

			It is completely and entirely unclear how you double-check to make sure Carbon has received this data correctly, where the data goes, anything.

			If you check the listener log file, you'll see something like this for each piece of data you send to the port Graphite/Carbon is listening to (specified with DESTINATION in carbon.conf file):

			<pre>
			25/06/2014 13:48:05 :: MetricPickleReceiver connection with 127.0.0.1:50787 established
			25/06/2014 13:48:05 :: MetricPickleReceiver connection with 127.0.0.1:50787 closed cleanly
			</pre>

			It would be nice if there were some additional information available, or some description of success or failure with respect to doing something with the data. Is it going in the database? Is the database even running? What happens if it isn't? Who knows.
