# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!

# ### sample forwarding rule ###
#action(type="omfwd"
# # An on-disk queue is created for this action. If the remote host is
# # down, messages are spooled to disk and sent when it is up again.
#queue.filename="fwdRule1" # unique name prefix for spool files
#queue.maxdiskspace="1g" # 1gb space limit (use as much as possible)
#queue.saveonshutdown="on" # save messages to disk on shutdown
#queue.type="LinkedList" # run asynchronously
#action.resumeRetryCount="-1" # infinite retries if host is down
# # Remote Logging (we use TCP for reliable delivery)
# # remote_host is: name/ip, e.g. 192.168.0.1, port optional e.g. 10514

STEP
/etc/rsyslog.confの定義をチェックする
rsyslogd -N 1コマンドで、/etc/rsyslog.confの定義をチェックします。
# rsyslogd -N 1
rsyslogd: version 8.2102.0-105.el9, config validation run (level 1), master config /etc/rsyslog.conf
rsyslogd: End of config validation run. Bye
定義が誤っていると、以下のように誤っている行が指摘されます。
# rsyslogd -N 1
rsyslogd: version 8.2102.0-105.el9, config validation run (level 1), master config /etc/rsyslog.conf
rsyslogd: error during parsing file /etc/rsyslog.conf, on or before line 82: warnings occured in file '/etc/rsyslog.conf' around line 82 [v8.2102.0-105.el9 try https://www.rsyslog.com/e/2207 ]
