Yes, collectd can both send and receive data with network plugin (see
http://www.collectd.org/wiki/index.php/Plugin:Network for details, the
keyword preceding the IP address/host name determines is sending or
receiving is done.

Some of them are certainly (though probably not all of them). Note
that all of them are being graphed with rrdtool (rrdtool or rrdcached
plugins can be used to produce the RRD files that can later be graphed).

Don't hesitate reading the wiki, man and FAQ pages, you will find a lot
of details over there (and the source code under contrib/ for samples of
graphing commands with rrdtool).
