用python监控java服务脚本(1)

java服务有的时候报了OutOfMemory错误后，进程还在哪里。为了即时发现这样的错误,写了这个脚本，用这个脚本定时扫描java服务日志文件的最后500行，如果有OutOfMemory错误，就给指定邮箱发送邮件。邮件内容包括：发生错误的主机和报错的文件。

 

#!/usr/bin/python
import string
import smtplib
from email.mime.text import MIMEText
import socket
import fcntl
import struct

logFiles = ['file.txt']  
pat = 'OutOfMemory'
mailserver = 'smtp.163.com'
username = '[e-mail]'
password = 'yy'
from_addr = '[e-mail]'
to_addr = '[e-mail]'

def get_ip_address(ifname):
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    return socket.inet_ntoa(fcntl.ioctl(s.fileno(),0x8915,struct.pack('256s', ifname[:15]))[20:24])

host = get_ip_address('eth0')

def fileScan(file,pattern):
        logFile = open(file,'r')
        logStrs = logFile.readlines()
        logLines = len(logStrs)
        logStr = str(logStrs[-10:logLines])
        try:
                logStat = logStr.index(pattern)
                if logStat:
                        return 1
        except ValueError:
                return 0

        logFile.close()

for f in logFiles:
        stat = fileScan(f,pat)
        if stat:
            msg = MIMEText('Host ip: ' + host + "\r\n" + 'OutOfMemory File: ' + f)
            msg['Subject'] = 'Java Service OutOfMemory'
            svr = smtplib.SMTP(mailserver)
            #svr.set_debuglevel(1)   #print debug
            svr.login(username,password)
            svr.sendmail(from_addr,to_addr,msg.as_string())
            svr.close()
