红帽全球峰会14.8. 系统崩溃后 kdump 生成的文件
系统崩溃后，kdump 服务会将内核内存捕获在转储文件(vmcore)中，它还会生成额外的诊断文件，以帮助故障排除和事后分析。
kdump 生成的文件：
-
vmcore- 崩溃时包含系统内存的主内核内存转储文件。它包含根据kdump配置中指定的core_collector程序配置的数据。默认情况下，包含内核数据结构、进程信息、堆栈跟踪和其他诊断信息。 -
vmcore-dmesg.txt- panic 的主内核中的内核环缓冲区日志的内容(dmesg)。 -
kexec-dmesg.log- 有从收集vmcore数据的辅助kexec内核执行中得到的内核和系统日志消息。
