python3 npar.py /u03/z.txt ‘(ORA-|REEOR)，(04030|02011)‘ 2

   第一个参数是日志路径  第二个参数是关键字 第三个参数为 匹配到第一个表达式这种的关键字后再去地 N(2)行去匹配第二个关键词（04030|02011）具体脚本实现如下

import os

import sys

logtxt="logtxt.txt"

def read_txt(files,start_line):

data =[]

data.append("")

with open(str(files)+"", "r", encoding=‘UTF-8‘) as f:

    for line in f.readlines():

       line = line.strip(‘\n‘)  #去掉列表中每一个元素的换行符

       data.append(line)

    #记录本次的行数

    wirte_log(len(data)-1)

if len(data)>start_line: 

   return data[start_line-1:]

else:

    print("开始行数大于文本文件总行数！")

def wirte_log(lines):

global logtxt

with open(logtxt,"w") as file:   #”w"代表着每次运行都覆盖内容

        file.write(str(lines))

def read_log():

global logtxt

if not os.path.exists(logtxt):

     with open(logtxt,"w") as file:   #”w"代表着每次运行都覆盖内容

        file.write(str(1))

with open(logtxt+"", "r", encoding=‘UTF-8‘) as f:

     s_lines = f.readlines()

print("从第"+str(s_lines[0])+"行开始")

return s_lines[0]

def deal_read_log(files, keyword, interval_line):

keywords = keyword.replace("(","").replace(")","").replace("‘","").replace(‘"‘,‘"‘).split(‘,‘)

start_keywords=keywords[0].split("|")

end_keywords = keywords[1].split("|")

start_line=read_log()

lines_data = read_txt(files,int(start_line))

for_line=1

while(for_line<len(lines_data)):

    #print(for_line)

    #print(lines_data[for_line])

    #if end_keywords in lines_data[for_line]:

    #      print(lines_data[for_line])

    #      print("-------------------")

    #      for_line = for_line+1

    #else:

        isexist = 0

        for sk in start_keywords:

            if sk in lines_data[for_line]:

                isexist=1

                break;

        if isexist==1:

        #if start_keywords[0] in lines_data[for_line] or start_keywords[1] in lines_data[for_line]:

            #当前行有end_keywords

            isexist2 = 0

            for sk in end_keywords:

                if sk in lines_data[for_line]:

                    isexist2=1

                    break;

            if isexist2==1:

                    #print("行数="+str(start_line-1+for_line)+"-"+str(start_line-1+for_line))

                    print(lines_data[for_line])

            else:

                #当前行没有end_keywords。往下interval_line行去寻找

                #标记当前行数

                flag_line = for_line

                count=1

                for_line = for_line+1

                while(for_line<len(lines_data)):

                    isexist3 = 0

                    for sk in end_keywords:

                        if sk in lines_data[for_line]:

                            isexist3=1

                            break;

                    if isexist3==1:

                         #print("行数="+str(start_line-1+flag_line)+"-"+str(start_line-1+for_line))

                         for prin in range(flag_line,for_line+1):

                              print(lines_data[prin])

                         break;

                    for_line = for_line+1

                    if count==int(interval_line):

                        break;

                    count = count+1

                for_line = for_line-1  

        for_line = for_line+1

if name == ‘main‘:

files = sys.argv[1]

if  ‘.log‘ in files:

  logtxt=files.replace(".log","_log.txt")

else:

     logtxt=files.replace(".txt","_log.txt")

#files="ora.txt"

keywords = sys.argv[2]

#keywords="‘((04030|04000)，ORA-)‘"

# 上下关联行数

interval_line = int(sys.argv[3])

#interval_line=10

deal_read_log(files, keywords, interval_line)

接下来就是添加监控了

在agent的conf 文件里面添加UserParameter

到这里监控就完成了
