python日志syslog运用

syslog的官方说明在:

https://docs.python.org/2/library/syslog.html#module-syslog

该模块的主要方式为:

#!/usr/bin/python
# -*- coding: utf-8 -*- import syslog syslog.openlog([ident[, logoption[, facility]]])
syslog.syslog(priority, message)
syslog.closelog()

ident 的信息为 /bluedon/test.py

logoption 的信息为 [4642]

facility 的信息为 记录日志文件的位置 ,本文选取的 facility = syslog.LOG_USER ,即日志输出在 /var/log/messages

源码为:

#!/usr/bin/python
# -*- coding: utf-8 -*-
import syslog
import os if __name__ == '__main__':
# https://docs.python.org/2/library/syslog.html
# syslog.openlog([ident[, logoption[, facility]]]) # ident
filename = os.path.abspath(__file__) # logoption
# LOG_CONS:如果将信息发送给守护进程时发生错误,直接将相关信息输入到相关信息输出到终端。
# LOG_NDELAY:立即打开与系统日志的连接(通常情况下,只有在产生第一条日志信息的情况下才会打开与日志系统的连接)
# LOG_NOWAIT:在记录日志信息时,不等待可能的子进程的创建
# LOG_ODELAY:类似于LOG_NDELAY参数,与系统日志的连接只有在syslog函数调用时才会创建
# LOG_PID:每条日志信息中都包括进程号
# LOG_PID, LOG_CONS, LOG_NDELAY, LOG_NOWAIT, LOG_PERROR
pid = syslog.LOG_PID # facility
# LOG_KERN, LOG_USER, LOG_MAIL, LOG_DAEMON, LOG_AUTH, LOG_LPR, LOG_NEWS, LOG_UUCP, LOG_CRON, LOG_SYSLOG, LOG_LOCAL0 to LOG_LOCAL7
filepath = syslog.LOG_USER # Priority
# LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, LOG_DEBUG
level = syslog.LOG_NOTICE # messages
messages = "test start14" # syslog.openlog([ident[, logoption[, facility]]])
syslog.openlog(filename, pid, filepath)
# syslog.syslog(priority, message)
syslog.syslog(level, messages)
# close syslog
syslog.closelog() # vim var/log/message
# tail -f /tmp/syslog.txt
