-TMON - A Monitoring and Testing Tool for Linux kernel thermal subsystem
-
-Why TMON?
-==========
-Increasingly, Linux is running on thermally constrained devices. The simple
-thermal relationship between processor and fan has become past for modern
-computers.
-
-As hardware vendors cope with the thermal constraints on their products, more
-and more sensors are added, new cooling capabilities are introduced. The
-complexity of the thermal relationship can grow exponentially among cooling
-devices, zones, sensors, and trip points. They can also change dynamically.
-
-To expose such relationship to the userspace, Linux generic thermal layer
-introduced sysfs entry at /sys/class/thermal with a matrix of symbolic
-links, trip point bindings, and device instances. To traverse such
-matrix by hand is not a trivial task. Testing is also difficult in that
-thermal conditions are often exception cases that hard to reach in
-normal operations.
-
-TMON is conceived as a tool to help visualize, tune, and test the
-complex thermal subsystem.
-
-Files
-=====
- tmon.c : main function for set up and configurations.
- tui.c : handles ncurses based user interface
- sysfs.c : access to the generic thermal sysfs
- pid.c : a proportional-integral-derivative (PID) controller
- that can be used for thermal relationship training.
-
-Requirements
-============
-Depends on ncurses
-
-Build
-=========
-$ make
-$ sudo ./tmon -h
-Usage: tmon [OPTION...]
- -c, --control cooling device in control
- -d, --daemon run as daemon, no TUI
- -l, --log log data to /var/tmp/tmon.log
- -h, --help show this help message
- -t, --time-interval set time interval for sampling
- -v, --version show version
- -g, --debug debug message in syslog
-
-1. For monitoring only:
-$ sudo ./tmon
