Logging can have different verbosity:
error is logging only errors.
warning is logging errors and warnings.
info is logging errors, warnings, and information
messages.
This level is used by default.
debug is logging errors, warnings, information messages,
and debug messages.
You can configure logging in the ppem-manager.yml manager
and ppem-agent.yml agent configuration files using the
log.level configuration parameter.
Logging changes take effect after the service restart.
