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
