The syslog module

(Unix only, Optional). This module sends messages to the system logger facility (syslogd). Exactly what happens to these messages is system-dependent, but they usually end up in a log file named /var/log/messages, /var/adm/syslog, or some variation thereof. (If you cannot find it, check with your favorite system administrator.)

Example: Using the syslog module

# File: syslog-example-1.py

import syslog
import sys

syslog.openlog(sys.argv[0])

syslog.syslog(syslog.LOG_NOTICE, "a log notice")
syslog.syslog(syslog.LOG_NOTICE, "another log notice: %s" % "watch out!")

syslog.closelog()
