25.5.2. 诊断信息
在 JON、Amazon CloudWatch 或手动检测到问题时，诊断信息的常见来源是：
/var/log/jboss_user-data.out是 jboss-ec2-eap init 和用户自定义配置脚本的输出。/var/cache/jboss-ec2-eap/包含实际的用户数据、启动实例使用的自定义脚本和自定义 CLI 命令。/var/log也包含从主机启动、JBoss EAP 6、httpd 和其他大多数服务采集的日志。
访问这些文件只能通过 SSH 会话。关于如何配置和建立与 Amazon EC2 实例间的 SSH 会话，请参考《Amazon EC 起步指南》。
