Adding a coniguration file (/etc/sysmon.ini). This will allow users to no monitor the temperature of speciic drives by ignoring them, as well as ignoring the performance from specific drives. For instance on a system running mdraid, you could ignore performance on all of the drives that make up the raid array, and ignore the temperature of the raid device.
