Usage: |
Usage: |
-f, --filename=FILE |
-i, --ignore-status |
FILE to load checks from (defaults to /etc/sensorsd.conf) |
Don't automatically check the status of sensors that report it. |
-s, --sensor=ID |
-f, --filename=FILE |
ID of a single sensor. "-s 0" means hw.sensors.0. |
FILE to load checks from (defaults to /etc/sensorsd.conf) |
-w, --warning=RANGE or single ENTRY |
-s, --sensor=ID |
Exit with WARNING status if outside of RANGE or if != ENTRY |
ID of a single sensor. "-s kate0.temp0" means hw.sensors.kate0.temp0 |
-c, --critical=INTEGER |
Overrides --filename. |
Exit with CRITICAL status if outside of RANGE or if != ENTRY |
-w, --warning=RANGE or single ENTRY |
|
Exit with WARNING status if outside of RANGE or if != ENTRY |
|
-c, --critical=RANGE or single ENTRY |
|
Exit with CRITICAL status if outside of RANGE or if != ENTRY |

FILE is in the same format as sensorsd.conf(5) plus some additional |
|
entries. These additional entries in the file are ignored by |
|
sensorsd(8). This means you can use the same config file for $PROGNAME |
|
as well as sensorsd(8). |

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: |
$PROGNAME understands the following entries: |
low, high, crit, warn, crit.low, crit.high, warn.low, warn.high |
|
|
|
An ENTRY depends on the type. The descriptions in sensorsd.conf(5) can be used when appropriate, or you can use the following: |
low, high, crit, warn, crit.low, crit.high, warn.low, warn.high, |
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. |
ignore, status |
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. |
An ENTRY depends on the type. 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, temp 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. |

indicator or drive - does a case sensitive match of each |

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. |
