ACPI日志重新启动

Question

我尝试谷歌，但没有一些有用的信息。我试着调试为什么我的服务器重新启动。我有一些ACPI的日志。有谁在我的服务器上按电源按钮吗？

[root ~]# grep -i acpi /var/log/messages-20150726

我得到了一些关于那个时间的信息日志：

I get some info log about that time:

Answer 1

基于此输出，似乎确实有人按了电源按钮，尽管这也可以根据系统使用IPMI或某种OOB管理接口(如KVM )的功能来实现，如果配置得当的话。如果系统具有某种类型的BMC和/或IPMI接口，则应该能够使用impitool <relevant connection options> sel list访问服务器/系统事件日志( Server/System Event，SEL)。访问SEL可能会向您提供更多关于重新启动时发生的事情的信息。
