Help

usage: sensors-fans [-h] [-V] [--always-ok] [-c CRIT] [-w WARN]

Return hardware fans speed. Fan speed is expressed in RPM (rounds per minute).

options:
  -h, --help            show this help message and exit
  -V, --version         show program's version number and exit
  --always-ok           Always returns OK.
  -c CRIT, --critical CRIT
                        Set the critical threshold for fan speed in RPM.
                        Default: 20000
  -w WARN, --warning WARN
                        Set the warning threshold for fan speed in RPM.
                        Default: 10000

Usage Examples

./sensors-fans --warning 10000 --critical 20000

Output:

dell_smm: dell_smm = 4714 RPM, dell_smm = 4428 RPM

States

  • WARN or CRIT if fan speed (RPM) is above a given threshold.

Perfdata / Metrics

  • for each fan: its speed (RPM)
