FILE is in the same format as sensorsd.conf(5). These additional entries in the file are ignored by sensorsd(8). $PROGNAME understands the following entries: |
FILE is in the same format as sensorsd.conf(5) plus some additional |
low, high, crit, warn, crit.low, crit.high, warn.low, warn.high |
entries. These additional entries in the file are ignored by |
|
sensorsd(8). |
|
|
An ENTRY depends on the type. The descriptions in sensorsd.conf(5) can be used when appropriate, or you can use the following: |
$PROGNAME understands the following entries: |
volts_dc, fanrpm or raw - Anything that includes digits. Anything that isn't a digit or period is stripped from the entry and the sensor output and they 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 matches 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. |
low, high, crit, warn, crit.low, crit.high, warn.low, warn.high |
|
|
A RANGE is a low ENTRY and a high ENTRY separated by a colon (:). |
