All logs are saved to /var/dump

admin@sonic:~$ ls -lh /var/dump/

-rw-r--r-- 1 root root 3.4M Feb 22 22:47 sonic_dump_sonic_20220222_224649.tar.gz

Users can pack the debug information using the –since flag since the given date.

admin@sonic:~$ sudo show techsupport --since="yesterday"

Users can pack the debug information without syslog files with the –nolog flag.

admin@sonic:~$ sudo show techsupport --nolog
