- fe.log/beINFO/相应截图
- 慢查询：
- Profile信息，获取Profile，通过Profile分析查询瓶颈
- 并行度：show variables like ‘%parallel_fragment_exec_instance_num%’;
- pipeline是否开启：show variables like ‘%pipeline%’;
- be节点cpu和内存使用率截图
- 查询报错：
- query_dump，怎么获取query_dump文件
- be crash
- be.out
- coredump，如何获取coredump
- 外表查询报错
- be.out和fe.warn.log
