Viewing Core Files from Junos OS Processes

When an internal Junos OS process generates a core file, you can find the output at /var/crash/ and /var/tmp/. For Junos OS Evolved, you can find the output core files at /var/core/ for Routing Engine core files and /var/lib/ftp/in/ for FPC core files. Using these directories provides a quick method of finding core issues across large networks.

Use the CLI command show system core-dumps to view core files.
