List coredumps of the Manager & child process of Varnish. This contains useful information such as: time of the crash, pid, uid, gid, signal, whether corefile is present, path of the executeable and size of the corefile. Gather further information of each coredump, such as but not limited to: command line, cgroup, stack traces of threads, loaded so, path of the corefile. Coredump analysis of the latest crash is done using coredumpctl, we invoke gdb on the coredump to get the backtrace. This depend on coredumpctl having --debugger-arguments.

Pulling this information later can be tricky. File format could have changed, symbols might be missing, etc. So, the best solution here is to run these commands on the Varnish server itself. Signed-off-by: Asad Sajjad Ahmed <asadsa@varnish-software.com>
