python日志syslog运用
syslog的官方说明在:
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
在不同机器上面查看结果:
将其写成了类
#!/usr/bin/python
# -*- coding: utf-8 -*-
import syslog
class mysyslog(object):
# level
# LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, LOG_DEBUG
debug = syslog.LOG_DEBUG
info = syslog.LOG_INFO
notice = syslog.LOG_NOTICE
warning = syslog.LOG_WARNING
err = syslog.LOG_ERR
crit = syslog.LOG_CRIT
alert = syslog.LOG_ALERT
emerg = syslog.LOG_EMERG
# logoption
# LOG_PID, LOG_CONS, LOG_NDELAY, LOG_NOWAIT, LOG_PERROR
# 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
cons = syslog.LOG_CONS
ndelay = syslog.LOG_NDELAY
nowait = syslog.LOG_NOWAIT
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
# kern = syslog.LOG_KERN
# user = syslog.LOG_USER
# mail = syslog.LOG_MAIL
# daemon = syslog.LOG_DAEMON
# auth = syslog.LOG_AUTH
# lpr = syslog.LOG_LPR
# news = syslog.LOG_NEWS
# uucp = syslog.LOG_UUCP
# cron = syslog.LOG_CRON
