check_lm_sensors is a Nagios plugin that monitors on-board sensors and hard disk temperatures on Linux systems. It is software that assists in detecting problems early and preventing system damage.
The plugin offers multiple features that allow users to specify a sensor along with warn and crit values. For instance, they can check if fan1 is above 1000 or 2000 by using the "-c fan1=1000,2000" option. In addition, users can specify sensors with spaces in their names by either escaping the space, quoting the name, or substituting the space with an underscore.
Check_lm_sensors also offers the "-d" option, allowing it to check the temperature of the drive. Its "-l" option allows users to list all the sensors found, making identification more manageable. The software enables the specification of the hddtemp binary and the sensors binary locations for enhanced accuracy.
With its verbose output, users can easily monitor and identify sensors, making it an efficient tool for system maintenance. The "--version" option prints the software's version, providing users with up-to-date software.
An example of this software in action would be "$ ./check_lm_sensors -v -c 'sda Temp'=30,5,10 -c '+2.5V'=0.2,0.3,2.5" which would return the found sensors and their temperature readings. The LM_SENSORS CRITICAL would then show the actual sensor and temperature details, making it easy for users to address critical issues swiftly.
Overall, check_lm_sensors offer users with an intuitive tool for monitoring sensors and hard disk temperatures on Linux systems. Its numerous options make it an efficient, time-saving software for system maintenance.
