✨ NAME ✨

check_lm_sensors — a Nagios plugin to monitor hardware sensors and disk temperatures 🦋

okay so real quick before we dive in: this whole thing is the CHECK_LM_SENSORS(7) page, and it comes to you from the User Contributed Perl Documentation corner of the world (shipped alongside perl v5.40.1, if you were wondering). it's a manual page, bestie. it tells you how to use the plugin. let's get into it 💅

🦋 DESCRIPTION 🦋

so check_lm_sensors is a Nagios plugin, right? its whole job — its entire personality — is monitoring the values of on board sensors and hard disk temperatures on Linux systems. that's it. that's the gig. she watches your temps so you don't have to, no cap 🌡️

💜 VERSION 💜

Version 3.1.1. yes, that's the one. write it down. periodt.

🌸 SYNOPSIS 🌸

here's the whole shape of it, verbatim, don't @ me:

 check_lm_sensors [--help] [--verbose] [--version] [OPTIONS]

 Options
  -?, --help      help
  -l, --low       specifies a check for a sensor value which is too low.
  -h, --high      specifies a check for a sensor value which is too high.
  -r, --range     specifies a check for a sensor value which should stay
                  in a given range.
  --rename        renames a sensor in the performance output (useful if you
                  want to have common names for similar sensors across different
                  machines)
  --sanitize      sanitize sensor names (e.g., removing spaces)
  --nosensors     disable checks on check lm_sensors
  --nodrives      disable checks on drive temperatures
  -d, --drives    enable checks on drive temperature
  --hddtemp_bin   manually specifies the location of the hddtemp binary
  --sensors_bin   manually specified the location of the sensors binary
  -v, --verbose   verbose output
  --version       prints $prog_name's version and exits

that's the whole menu, served fresh 🍓

🎀 REQUIRED ARGUMENTS 🎀

nothing here! the section exists, the section is empty, the section is thriving. she requires nothing from you. a low-maintenance queen 👑

💅 OPTIONS 💅

the original page keeps all of these up in the SYNOPSIS, but here they are again in bullet form because we love a good list moment:

  • -?, --help — help. that's it, that's the description. iconic brevity.
  • -l, --low — specifies a check for a sensor value which is too low.
  • -h, --high — specifies a check for a sensor value which is too high.
  • -r, --range — specifies a check for a sensor value which should stay in a given range.
  • --rename — renames a sensor in the performance output. useful if you want to have common names for similar sensors across different machines 🫶
  • --sanitize — sanitize sensor names (e.g., removing spaces).
  • --nosensors — disable checks on check lm_sensors.
  • --nodrives — disable checks on drive temperatures.
  • -d, --drives — enable checks on drive temperature.
  • --hddtemp_bin — manually specifies the location of the hddtemp binary.
  • --sensors_bin — manually specified the location of the sensors binary.
  • -v, --verbose — verbose output.
  • --version — prints $prog_name's version and exits.

🌈 EXAMPLE 🌈

empty. a blank canvas. a vibe, truly. no examples were provided in the original, so no examples will be invented here — we don't make stuff up in this house 🙈

🔥 DIAGNOSTICS 🔥

You can specify multiple --verbose options to increase the program verbosity.

stack 'em up like little verbose bracelets, bestie ✨

⭐ EXIT STATUS ⭐

  • 0 if OK
  • 1 in case of a warning
  • 2 in case of a critical status
  • 3 in case of an unknown problem

🧚 DEPENDENCIES 🧚

the page says, quote unquote, check_updates depends on — yes, it literally says check_updates there, and no, we are not editing the source material. we report, we don't fix 💀 anyway, here's what it depends on:

  • Carp
  • English
  • Getopt::Long
  • Monitoring::Plugin
  • Monitoring::Plugin::Threshold
  • version

🌸 CONFIGURATION 🌸

another empty one. nothing to configure here, babe. it's giving minimalist 🎀

💜 INCOMPATIBILITIES 💜

None reported. she plays nice with everyone 🫶

yes bestie, all caps means it's serious serious. the lawyers wrote this one, not me. I'm just the messenger 💅

🌟 ACKNOWLEDGMENTS 🌟

blank. nothing but good vibes and empty space 🌈

and that's the whole page, bestie! this was CHECK_LM_SENSORS(7), part of the User Contributed Perl Documentation, living its life under perl v5.40.1 — and the last time anyone stamped a date on it was 2026-02-11. now go check those temps 💖✨
