Probe disk performance (MRTG)

The hdparam can be used to monitor the throughput speed of a hard disk:
# <strong>hdparm -tT /dev/hda</strong>
/dev/hda:<br /> Timing buffer-cache reads: 888 MB in 2.00 seconds = 444.00 MB/sec<br /> Timing buffered disk reads: 20 MB in 3.30 seconds = 6.06 MB/sec

This would be an interesting performance metric to see plotted against time. So let’s convert it to a format ready for MRTG.
