<html> <body> Jeffrey: You should check to make sure that lm_sensors package is really running. Quite a number of machines don't support that package. The program starts then quitely dies. Example: Dell's don't support it at all. (or if I'm incorrect on that someone in the group correct me and then tell me how to make it work) An IBM intellistation which I thought might, won't either. try a ps -ef | grep sensors Doug At 09:47 AM 3/23/2006, Jeffrey Montgomery wrote: <blockquote type=cite class=cite cite="">Can anyone explain how to use the check_sensor plugin?
