在实际生产中会经常需要自定义一些各种中间件的监控项,自己一个个添加的话太繁琐了,之所以在zabbix官网和第三方网站都会提供大量的监控模板,有的写的非常可以,我们在生产中的话是可以去下载一些模板,并进行修改成自己适合的监控模版使用到生产环境中,这样的话也简便和高效。这里我还是在Linux主机上操作。
1、部署nginx服务
如果是使用编译安装nginx的话,需要添加--with-http_stub_status_module这个编译的参数,这里我就演示一下编译安装nginx了。
#安装nginx的时候也是要同时安装zabbix agent的,这里我就不安装zabbix agent了,我使用的这个主机在监控Linux主机是安装了,没安装的话可以执行下面的命令安装,安装了的话就直接执行apt -y install nginx就可以了

Active connections: 3
server accepts handled requests

Reading: 0 Writing: 1 Waiting: 2
名词解释
Active connections:当前出于活动状态的客户端连接数,包括连接等待空闲连接数
accepts:统计总值,Nginx自启动后已经接受的客户端请求的总数
handled:统计总值,Nginx自启动后已经处理完成的客户端请求的总数,通常此值等于accepts的值,除非因worker_coonections限制等被拒绝的连接
requests:统计总值,Nginx自启动后客户端发来的总的请求数
Reading: 当前状态,正在读取客户端请求报文首部的连接的连接数
Writing: 当前状态,正在向客户端发送响应报文过程中的连接数
Waiting: 当前状态,正在等待客户端发出请求的空闲连接数,开启keep-alive的情况下,这个值等于active - (Reading+Writing)
2、编辑监控获取数据的脚本
#在生产中的连接数是不止这么多的,这数值是我刚刚用了循环语句造的
root@zabbix-server:~# curl http://10.0.0.102/nginx_status
Active connections: 1
server accepts handled requests

Reading: 0 Writing: 1 Waiting: 0

nginx_status_fun(){
NGINX_PORT=$1
NGINX_COMMAND=$2
nginx_active(){
/usr/bin/curl http://10.0.0.102:"${NGINX_PORT}"/nginx_status 2> /dev/null | grep 'Active' | awk '{print $NF}'
}
nginx_reading(){
/usr/bin/curl http://10.0.0.102:"${NGINX_PORT}"/nginx_status 2> /dev/null | grep 'Reading' | awk '{print $2}'
}
nginx_writing(){
/usr/bin/curl http://10.0.0.102:"${NGINX_PORT}"/nginx_status 2> /dev/null | grep 'Writing' | awk '{print $4}'

3、Zabbix agent添加自定义监控项
root@Linux:~# vim /etc/zabbix/zabbix_agentd.conf
root@Linux:~# grep -Ev "#|^$" /etc/zabbix/zabbix_agentd.conf
PidFile=/tmp/zabbix_agentd.pid
LogFile=/tmp/zabbix_agentd.log
LogFileSize=0
Server=10.0.0.100,10.0.0.104
ListenPort=10050
ListenIP=0.0.0.0
StartAgents=3
ServerActive=10.0.0.104
Hostname=10.0.0.102
Timeout=30
AllowRoot=1
User=root
Include=/etc/zabbix/zabbix_agentd.d/*.conf
UserParameter=linux_status[*],/etc/zabbix/zabbix_agentd.d/tcp_conn_plugin.sh "$1" "$2"
UserParameter=memcache_status[*],/etc/zabbix/zabbix_agentd.d/memcache_monitor.sh "$1" "$2" "$3"
UserParameter=redis_status[*],/etc/zabbix/zabbix_agentd.d/redis_monitor.sh "$1" "$2" "$3"
UserParameter=nginx_status[*],/etc/zabbix/zabbix_agentd.d/nginx_monitor.sh "$1" "$2" "$3"
root@Linux:~# systemctl restart zabbix-agent
4、在Zabbix server上测试是否可以获取数据
root@zabbix-server:~# zabbix_get -s 10.0.0.102 -p 10050 -k "nginx_status["nginx_status",80,"active"]"
1
root@zabbix-server:~# zabbix_get -s 10.0.0.102 -p 10050 -k "nginx_status["nginx_status",80,"reading"]"
0
5、导入之前做好的nginx监控模板
监控模板可以到zabbix官网上和第三方网站上下载,上面有很多的模板可以下载,不过有些模板下载下来后需要修改一下,修改完后就可以导入模板进行使用了。
6、关联主机的监控模板并验证数据
