If, as greg asks, you mean a process crashes and you get a “core dump”: Most systems will have a pipe (|) in this setting to indicate that a program needs to take care of the generated data. Echo '/tmp/cores/core' | sudo tee /proc/sys/kernel/core_pattern the executable file name, pid of the process, and a timestamp can also be added to. The initial configuration assigns each core dump the following storage address (to avoid duplicate storage): Additionally, various size limits for the storage can be configured. If it doesn't exist, go to edit > new > key and name it localdumps. For example if you want core dumps in /var/crash: * zstd (due to compress); Get the coredump file from running process using below command, gcore. Locate the localdumps key in the path.
