3 Things we have to do in order of importance.
5 * Asynchronously write data to RRDs. (Data is written when collected ATM.)
7 * Exit all threads on SIGTERM (Call shutdown method).
8 * Fork daemon on startup.
9 * Improve RRD format (choice of steps, etc.)
11 * Better error handling of mistakes in the config file.
14 * CPU Usage (almost done).
15 * Load Average (almost done).
16 * Memory Usage (almost done).
17 * Disk space (with standby).
19 Bridge (AREA) plus slave interfaces in the same graph (LINE).
21 * (QoS - very expensive work.)
