什么是tmon，我如何使用它？

Question

我在我的tmon 7.5中找到了一个CentOS实用程序，我在谷歌上搜索了这个工具：

TMON是用来帮助可视化、调优和测试复杂的热子系统的工具。..。仅用于监测：$ sudo ./tmon https://github.com/torvalds/linux/tree/master/tools/thermal/tmon

但是由于这次发射，我只得到了一个错误：

No thermal zones found, exit

在我的E5-2620 v4和内核3.10.0-862.11.6.el7.x86_64上。

我还发现了其他一些不太好的地方和类似的话题(比如RH：https://bugzilla.redhat.com/show_bug.cgi?id=1466991上的这个)，但是它还没有弄清楚如何正确地使用它来监控，以及这个“区域”意味着什么。

UPD此CentOS位于裸金属服务器上。

您可能需要加载主板的某些内核模块才能获得热区读数，下面是使用lm-传感器包从Ubuntu14.04LTS裸金属服务器读取的数据

您可以使用lm-sensors包来识别您需要加载的模块，检查man sensors-detect。
