Describe the results you received:

It's caused by #19232
In syslogger.py, it sets default level to NOTICE, which is higher than INFO.
Even it set min log priority to INFO, but INFO still disappear in syslog file.
https://github.com/sonic-net/sonic-host-services/blob/master/scripts/caclmgrd

    # Log all messages from INFO level and higher
    caclmgr.set_min_log_priority_info()

We need to set level to INFO, no NOTICE, or set NOTICE priority smaller than INFO.

Describe the results you expected:

Need to check INFO level logs in syslog
