This article mainly introduces the relevant knowledge of "Zabbix custom script monitoring nginx and WeChat alarm method". Xiaobian shows you the operation process through actual cases. The operation method is simple, fast and practical. I hope this article "Zabbix custom script monitoring nginx and WeChat alarm method" can help you solve the problem.

item description

The purpose of this project is to build a zabbix monitoring system that can realize WeChat alarm, which can monitor the entire NGINX cluster conveniently, and at the same time can deploy and manage the entire cluster in batches.

project steps

Install zabbix server on zabbix server (192.168.2.138), zabbix agent on nginx (192.168.2.58), configure Nginx Load Balancer cluster, and open status statistics.

Write a monitoring script on the nginx side to get the status of nginx.

Add monitoring items to server-side web, and show the diagram.

Register enterprise WeChat and configure WeChat interface.

zabbix server added interface push script, test interface normal.

Configure alarm media, groups and users on the web side, add relevant triggers and actions.

Nginx shutdown service, test whether it can be alerted through WeChat.

Project knowledge

In the process of receiving messages, the return value has always been the parameter {ALTER.MESSAGE}, troubleshooting script problems, version problems, and finally found that it is the parameter {ALERT.MESSAGE}, so typing must be careful and serious. At the same time, I also have a certain understanding of monitoring. It is impossible for operation and maintenance personnel to stare at zabbix 24 hours a day, so it is very necessary to give timely warnings. The previous high availability web cluster project leaf can be improved.

Detailed steps zabbix-agent client nginx configuration monitoring

nginx open status statistics function

Add stub_status module to nginx configuration

location = /wyt_status{stub_status;}

Test whether the status statistics function is turned on

http://192.168.2.58/wyt_status\

nginx (zabbix client) Write monitoring scripts

cd /etc/zabbix/zabbix_agentd.d #Write a monitoring script vim zabbix-nginx_status.sh#!/in the zabbix_agentd.d directory bin/bashcase $1 in active) curl http://192.168.2.58:80/wyt_status 2>/dev/null|awk '/Active/ {print $NF}' ;; accepts) curl http://192.168.2.58:80/wyt_status 2>/dev/null|awk 'NR==3 {print $1}' ;; handled) curl http://192.168.2.58:80/wyt_status 2>/dev/null |awk 'NR==3 {print $2}' ;; requests) curl http://192.168.2.58:80/wyt_status 2>/dev/null |awk 'NR==3 {print $3}' ;; reading) curl http://192.168.2.58:80/wyt_status 2>/dev/null |awk 'NR==4 {print $2}' ;; writing) curl http://192.168.2.58:80/wyt_status 2>/dev/null |awk 'NR==4 {print $4}' ;; waiting) curl http://192.168.2.58:80/wyt_status 2>/dev/null |awk 'NR==4 {print $NF}' ;; ping) pidof nginx |wc -l #Test nginx survival status by querying process PID values ;; esacvim userparameter_nginx.conf#Customize parameter configuration file under zabbix_agentd.d UserParameter=nginx.status[*],/etc/zabbix/zabbix_agentd.d/zabbix-nginx_status.sh $1#Specify action chmod +x zabbix-nginx_status.sh#Grant executable permission service zabbix-agent restart#Refresh service zabbix_get -k nginx.status[ping] -s 192.168.2.58#Go to server test whether to return parameter 1zabbix-server-web configuration monitoring

First create nginx host master-nginx

Add app set nginx

在应用集nginx增加监控项

自定义触发器nginx-up-down，监控项为nginx-ping，正常为1，每5s监控一次，若为0，严重警告。

除nginx-ping，nginx-accepts外，需要添加所有状态监控项，只有nginx-ping创建触发器，这里不一一举例。

添加好所有监控项，下一步制图，图中包含所有监控项

因为我们监控实际上就是在一直请求，所以看到nginx-requests在不断增加。

注册企业微信接口

注册成功之后创建一个运维部门

记住自己的企业ID

自建应用

应用名称为zabbix监控

创建成功后，查看信息记住自己的AgentId和Secret

微信扫码企业微信插件就可以在微信接收消息

zabbix-server接口脚本配置告警

Shell脚本

cd /usr/lib/zabbix/alertscripts进入脚本配置文件夹vim weixin.sh#!/bin/bashCorpID="wwaa6fb8ff1b81aa77" # 你的企业idSecret="Cxyd*****" #你的SecretIDGURL="https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$CorpID&corpsecret=$Secret"Token=$(/usr/bin/curl -s -G $GURL |awk -F\": '{print $4}'|awk -F\" '{print $2}')# echo $TokenPURL="https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=$Token"function body(){ local int agentid=1000002 # 你的agentdid local UserID="@all" # 发送的用户ID local PartyID=1 # 部门ID local Msg=$(echo "$@" | cut -d" " -f3-) # 发送给所有人 printf '{\n' printf '\t"touser": "'"$UserID"\"",\n" printf '\t"toparty": "'"$PartyID"\"",\n" printf '\t"msgtype": "text",\n' printf '\t"agentid": "'"$agentid"\"",\n" printf '\t"text": {\n' printf '\t\t"content": "'"$Msg"\""\n" printf '\t},\n' printf '\t"safe":"0"\n' printf '}\n'}/usr/bin/curl --data-ascii "$(body $1 $2 $3)" $PURL

测试脚本能否正常接收消息

可以看到正常接收。

然后我们回到zabbix-server-web配置

zabbix-server-web配置告警

管理->报警媒介类型->创建媒体类型

创建用户群组

创建用户

报警媒介

权限->超级管理员

配置->动作

添加触发器

操作

故障{TRIGGER.STATUS},服务器:{HOSTNAME1}发生{TRIGGER.NAME}故障!

告警主机:{HOSTNAME1}

告警时间:{EVENT.DATE} {EVENT.TIME}

告警等级:{TRIGGER.SEVERITY}

告警信息: {TRIGGER.NAME}

告警项目:{TRIGGER.KEY1}

问题详情:{ITEM.NAME}:{ITEM.VALUE}

当前状态:{TRIGGER.STATUS}:{ITEM.VALUE1}

事件ID:{EVENT.ID}

恢复操作

恢复{TRIGGER.STATUS}, 服务器:{HOSTNAME1}: {TRIGGER.NAME}已恢复!

告警主机:{HOSTNAME1}

告警时间:{EVENT.DATE} {EVENT.TIME}

告警等级:{TRIGGER.SEVERITY}

告警信息: {TRIGGER.NAME}

告警项目:{TRIGGER.KEY1}

问题详情:{ITEM.NAME}:{ITEM.VALUE}

当前状态:{TRIGGER.STATUS}:{ITEM.VALUE1}

事件ID:{EVENT.ID}

zabbix-agent关停nginx服务测试

可以看到推送成功

Python webhook机器人脚本

新建一个测试群聊，在群里添加机器人，记住webhook地址

除了使用Shell脚本配置接口之外，还可以使用Python脚本

#!/usr/bin/python#-*- coding: utf-8 -*-import requestsimport jsonimport sysimport osheaders = {'Content-Type': 'application/json;charset=utf-8'}api_url = "https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=****"#填写自己的webhook地址def msg(text): json_text= { "msgtype": "text", "text": { "content": text }, } print requests.post(api_url,json.dumps(json_text),headers=headers).contentif __name__ == '__main__': text = sys.argv[1] msg(text)

测试

python weixin.py test

web配置同上
