![ACPI 日志重启](https://linux22.com/image/663836/ACPI%20%E6%97%A5%E5%BF%97%E9%87%8D%E5%90%AF.png)
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?

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。
