[Feature Request] Turn on DEBUG log for all commands

[jiasli]

Context

There could be a method to turn on DEBUG log for all commands, like turning on DEBUG log for all PowerShell cmdlets through

$DebugPreference = "Continue"

Currently, CLI can enable log file with logging.enable_log_file (https://docs.microsoft.com/en-us/cli/azure/azure-cli-configuration) which prints all levels of logs.

Proposals

Add core.debug config option

A config option core.debug can be added, like core.only_show_error. However, there will still be no option to always show INFO logs.

Add core.log_level config option and --log-level argument

Like log_cli_level from pytest (https://docs.pytest.org/en/6.2.x/logging.html#live-logs), a more general solution is to add core.log_level config option and --log-level argument which can be set to

• debug
• info
• warning
• error

This is a superset of

• core.only_show_errors/--only-show-errors (Support --only-show-errors microsoft/knack#179), which is equivalent to core.log_level=error/--log-level error
• --debug, which is equivalent to core.log_level=debug/--log-level debug
• --verbose, which is equivalent to core.log_level=info/--log-level info
