男人核心告诉我们：
Piping core dumps to a program
Since kernel 2.6.19,Linux supports an alternate syntax for the
/proc/sys/kernel/core_pattern file. If the first character of this
file is a pipe symbol (|),then the remainder of the line is
interpreted as a program to be executed. Instead of being written to
a disk file,the core dump is given as standard input to the program.
Note the following points:
-
The program must be specified using an absolute pathname (or a
pathname relative to the root directory,/),and must immediately
follow the ‘|’ character.
-
The process created to run the program runs as user and group
root.
-
Command-line arguments can be supplied to the program (since Linux
2.6.24),delimited by white space (up to a total line length of
128 bytes).
-
The command-line arguments can include any of the % specifiers
listed above. For example,to pass the PID of the process that is
being dumped,specify %p in an argument.
你可以在那里放一个脚本,例如
| /path/to/myscript %p %s %c
您可以检测哪个进程正在触发coredump
