nagios自定义监控API插件

231211

监控思路：通过url访问某一接口文件的具体返回内容，正则匹配某一接口存活必定含有的字符，若有则证明接口存活，若无则接口有问题。  废话不多说，上插件：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54

#!/usr/bin/env python # -*- coding: utf-8 -*- import re import urllib import sys import getopt def usage():     print """Usage: check_api [-h|--help] [-u|--url url] [-S|--Str String] " Url: the url that you want to check; String: the string that you want to match; " For example,#/usr/local/nagios/libexec/check_api -u 'http://xxx.com/ch1.ashx?jsoncallback=jQuery111104933076921983046_1479864376576&classid=12&systemtype=2&dataType=json&cityid=129&videoid=36065812&pageid=1&_=1479864376577' -S AdList """     sys.exit(3) def getHtml(url):     page = urllib.urlopen(url)     html = page.read()     return html def getString(Str, html):     matchObj = re.search(Str, html, re.M)     if matchObj:         print("GET API OK：get %s successfully!" % Str)         sys.exit(0)     elif not matchObj:         print("GET API CRITICAL：the API was error!")         sys.exit(2)     else:         print("GET API UNKNOWN：the API was unknow!")         sys.exit(3) try:     options, args = getopt.getopt(sys.argv[1:],         "hu:S:",         "--help --url= --Str=",         ) except getopt.GetoptError:     usage()     sys.exit(3) for name, value in options:     if name in ("-h", "--help"):         usage()     if name in ("-u", "--url"):         url = value     if name in ("-S", "--Str"):         Str = value html = getHtml(url) getString(Str, html)

返回结果：

1 2	[iyunv@M-WEB-065 ~]# /usr/local/nagios/libexec/check_api -u 'http://xxx.com/ch1.ashx?jsoncallback=jQuery111104933076921983046_1479864376576&classid=12&systemtype=2&dataType=json&cityid=129&videoid=36065812&pageid=1&_=1479864376577' -S AdList GET API OK：get AdList successfully!

一、上述插件在客户机上部署，将此插件放入/usr/local/nagios/libexec/  赋予可执行权限和属主组，修改/usr/local/nagios/etc/nrpe.cfg配置文件，添加

1	command[check_api]=/usr/local/nagios/libexec/check_api -u 'http://xxx.com/ch1.ashx?jsoncallback=jQuery111104933076921983046_1479864376576&classid=12&systemtype=2&dataType=json&cityid=129&videoid=36065812&pageid=1&_=1479864376577' -S AdList

重启nagios客户端。
二、修改监控主机/usr/local/nagios/etc/objects/commands.cfg文件，添加

1 2 3 4

define command{         command_name check_api         command_line $USER1$/check_api -u $ARG1$ -S $ARG2$         }

修改监控主机/usr/local/nagios/etc/objects/services.cfg文件，添加

1 2 3 4 5 6 7 8 9 10 11 12 13 14

##############################M-WEB-065 check_api##################################### define service{         host_name               M-WEB-065         service_description     check_api         check_command           check_nrpe!check_api         max_check_attempts      5         normal_check_interval   5         retry_check_interval    2         check_period            24x7         notification_interval   10         notification_period     24x7         notification_options    u,c,r         contact_groups          yunwei }

最后重启nagios，查看监控结果
