The descriptions in sensorsd.conf(5) +can be used when appropriate, or you can use the following: -A RANGE is a low ENTRY and a high ENTRY separated by a colon (:). + fanrpm, volts_dc, amps, watthour, amphour, integer (raw), percent, + lux or timedelta - Anything that includes digits. Both the value of + the check and the value of the sensor response that are not either a + digit or period are stripped and then the two resultant values are + compared. + temp - Can be as above, but if the entry has an F in it, + it compares farenheit, otherwise it uses celcius. + + indicator or drive - does a case sensitive match of each + entry in the comma separated list and if it does not match + any of the entries, it sets the status. + +The entries 'crit' or 'warn' (or the -c or -w on the command line) +may be a RANGE or a comma separated list of acceptable values. +The comma separated list of values contains a list of things that +will NOT cause the status. This is possibly counterintuitive, but +you are more likely to know good values than bad values. + +A RANGE is a low ENTRY and a high ENTRY separated by a colon (:). +It can also be low: or :high with the other side left blank to only +make the single check. + +An entry marked "ignore" will cause that sensor to be skipped. +Generally used with state checking of all sensors to ignore sensors you +don't care about or that report incorrectly. + +If you are using --ignore-status, you can still check the status of +individual sensors with a status entry. + EOL - - print_revision($PROGNAME, '$Revision: 1.4 $'); + + print_revision( $PROGNAME, '$Revision: 1.31 $' ); + + print $License; +} + +sub print_revision { + my ( $prog, $rev ) = @_; + $rev =~ s/^\D+([\d\.]+)\D+$/v$1/xms; + + print "$prog $rev\n"; }
