Do you access the ASA with Cisco ASDM or SSH (CLI) ?

I am looking on CLI.

For everything:

logging monitor debugging

terminal monitor

Turn off with "terminal no monitor"

Thanks for the answer.

Is there any adverse impact on running the "logging monitor debugging" on the CLI, as heard that running debug command on Production firewall is not recommended.

Also, some ASA context, when i run the "show logging" command, I get the previous logs and other ASA, i get the logging settings as below. why is this difference caused by? Please help.
