1 TMON - A Monitoring and Testing Tool for Linux kernel thermal subsystem 2 3 Why TMON? 4 ========== 5 Increasingly, Linux is running on thermally constrained devices. The simple 6 thermal relationship between processor and fan has become past for modern 7 computers. 8 9 As hardware vendors cope with the thermal constraints on their products, more 10 and more sensors are added, new cooling capabilities are introduced. The 11 complexity of the thermal relationship can grow exponentially among cooling 12 devices, zones, sensors, and trip points. They can also change dynamically. 13 14 To expose such relationship to the userspace, Linux generic thermal layer 15 introduced sysfs entry at /sys/class/thermal with a matrix of symbolic 16 links, trip point bindings, and device instances. To traverse such 17 matrix by hand is not a trivial task. Testing is also difficult in that 18 thermal conditions are often exception cases that hard to reach in 19 normal operations. 20 21 TMON is conceived as a tool to help visualize, tune, and test the 22 complex thermal subsystem. 23 24 Files 25 ===== 26 tmon.c : main function for set up and configurations. 27 tui.c : handles ncurses based user interface 28 sysfs.c : access to the generic thermal sysfs 29 pid.c : a proportional-integral-derivative (PID) controller 30 that can be used for thermal relationship training. 31 32 Requirements 33 ============ 34 Depends on ncurses 35 36 Build 37 ========= 38 $ make 39 $ sudo ./tmon -h 40 Usage: tmon [OPTION...] 41 -c, --control cooling device in control 42 -d, --daemon run as daemon, no TUI 43 -l, --log log data to /var/tmp/tmon.log 44 -h, --help show this help message 45 -t, --time-interval set time interval for sampling 46 -v, --version show version 47 -g, --debug debug message in syslog 48 49 1. For monitoring only: 50 $ sudo ./tmon
