+### "How do I view the dmp file?"
+
+The dmp file is an error report file detailing the process exit information, which can be viewed with the gdb tool that comes with the operating system. The dmp file is saved in the current directory of the startup binary(default is `/usr/local/nebula` directory) and will be generated automatically when the NebulaGraph service crashes.
+1. Check the Core file process name, pid is usually a numeric value.
+   ```
+   $ file core.<pid>
+   ```
+2. Use gdb to debug.
+   ```
+   $ gdb <process.name> core.<pid>
+   ```
+3. View the contents of the file.
+   ```
+   $(gdb) bt
+   ```
+For example:
+```bash
+$ file core.1316027
+core.1316027: ELF 64-bit LSB core file, x86-64, version 1 (SYSV), SVR4-style, from '/home/workspace/fork/nebula-debug/bin/nebula-metad --flagfile /home/k', real uid: 1008, effective uid: 1008, real gid: 1008, effective gid: 1008, execfn: '/home/workspace/fork/nebula-debug/bin/nebula-metad', platform: 'x86_64'
+
+$ gdb /home/workspace/fork/nebula-debug/bin/nebula-metad core.1316027
+
+$(gdb) bt
+#0  0x00007f9de58fecf5 in __memcpy_ssse3_back () from /lib64/libc.so.6
+#1  0x0000000000eb2299 in void std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::_M_construct<char*>(char*, char*, std::forward_iterator_tag) ()
+#2  0x0000000000ef71a7 in nebula::meta::cpp2::QueryDesc::QueryDesc(nebula::meta::cpp2::QueryDesc const&) ()
+...
+```
+
+If the user is not sure about the information related to the dmp printout, you can post the printout on the [NebulaGraph Forum](https://github.com/vesoft-inc/nebula/discussions) with the operating system version, hardware configuration, error logs before and after the Core file was generated and actions that may have caused the error for help.
