ACPI 日志重启

我尝试谷歌搜索，但没有找到有用的信息。我尝试调试我的服务器为什么会重启。我有一些来自 ACPI 的日志。根据这个日志，有人按下了我服务器上的电源按钮吗？

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

更新：

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:

答案1

根据此输出，似乎确实有人按下了电源按钮，但这也可以虚拟地完成，具体取决于使用 IPMI 或某种 OOB 管理接口（如 KVM，如果配置正确）的系统功能。如果系统具有某种 BMC 和/或 IPMI 接口，您应该能够使用 访问服务器/系统事件日志 (SEL) impitool <relevant connection options> sel list。 访问 SEL可能会为您提供有关重启时发生的情况的更多信息。
