zabbix监控Nginx
A机器：zabbix服务端（192.168.234.128）
B机器：zabbix客户端（192.168.234.125）
在B机器（zabbix客户端）操作：
编辑nginx虚拟主机配置文件：
[root@centos ~]# vi /etc/nginx/conf.d/default.conf
在server{}中添加以下内容：
location /nginx_status
{
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
重载nginx配置：
[root@centos ~]# nginx -s reload
测试：
[root@centos ~]# curl http://127.0.0.1/nginx_status
Active connections: 1
server accepts handled requests
3 3 3
Reading: 0 Writing: 1 Waiting: 0
#nginx状态信息已显示
状态说明：
| 字段 | 含义 |
|---|---|
| Active Connections | 当前活动连接数，其中也包括了等待状态的连接 |
| accepts | 接收到的连接数 |
| handled | 已经处理完的连接数，该数字一般和accepts一致，如果不一致那么说明Nginx出错了 |
| requests | 总共处理的请求数，一个连接可以有多个请求，所以该值比accpets要大或相等 |
| Reading | 正在读取请求头信息的连接数 |
| Writing | 正在发送响应报文的连接数 |
| Waiting | 处于闲置状态，等待客户端发送请求的连接数 |
添加监控脚本:
vi /usr/local/sbin/ngx_status.sh
添加以下内容：
#!/bin/bash
url="http://127.0.0.1/nginx_status"
curl=/usr/bin/curl
# 检测nginx进程是否存在
function ping {
/sbin/pidof nginx | wc -l
}
# 检测nginx性能
function active {
$curl $url 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
$curl $url 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
$curl $url 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
$curl $url 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
$curl $url 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
$curl $url 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
$curl $url 2>/dev/null| awk NR==3 | awk '{print $3}'
}
$1
添加权限：
[root@centos ~]# chmod 755 /usr/local/sbin/ngx_status.sh
编辑zabbix_agent配置文件：
[root@centos ~]# vi /etc/zabbix/zabbix_agentd.conf
在Option：UserParameter处添加：UserParameter=nginx.status[*],/usr/local/sbin/ngx_status.sh $1
重启服务：
[root@centos ~]# systemctl restart zabbix-agent
在A机器（服务端）测试：
[root@zabbix ~]# zabbix_get -s 192.168.234.125 -k 'nginx.status[accepts]'

在本机创建.xml文件并添加以下内容：（文件名称自定义）
<?xml version="1.0" encoding="UTF-8"?>

在zabbix前端页面点击配置→模板→导入：
#导入刚才创建的xml文件即可
导入成功后在主机列表页面选择被监控的机器（B机器）链接该模板即可开始监控nginx
zabbix监控Tomcat
A机器：zabbix服务端（192.168.234.128）
B机器：zabbix客户端（192.168.234.125）
在A机器安装zabbix-java-gateway：
[root@zabbix ~]# wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm
[root@zabbix ~]# yum -y localinstall zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm
编辑gateway配置文件：
[root@zabbix ~]# vi /etc/zabbix/zabbix_java_gateway.conf
去掉LISTEN_IP、LISTEN_PORT(监听端口)、START_POLLERS(进程数)的注释符号#：
#LISTEN_IP定义被监控机器的地址，不指定默认监听全部机器
编辑server配置文件：
[root@zabbix ~]# vi /etc/zabbix/zabbix_server.conf
定义以下3个配置参数：
启动zabbix-java-gateway服务：
[root@zabbix ~]# systemctl start zabbix-java-gateway
重启zabbix-server服务：
[root@zabbix ~]# systemctl restart zabbix-server
查看监听端口：
[root@zabbix ~]# netstat -lntp |grep java
tcp6 0 0 :::10052 :::* LISTEN 8706/java
开启JMX
在B机器编辑tomcat配置文件：
[root@centos ~]# vi /usr/local/tomcat/bin/catalina.sh
添加以下内容：
export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote
-Djava.rmi.server.hostname=192.168.234.125
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"
#hostname定义B机器地址，端口9999（默认12345）
重启tomcat：
[root@centos ~]# /usr/local/tomcat/bin/shutdown.sh
[root@centos ~]# /usr/local/tomcat/bin/startup.sh
查看监听端口9999：
[root@centos ~]# netstat -lntp |grep 9999
tcp6 0 0 :::9999 :::* LISTEN 25861/java
进入zabbix前端页面添加主机：
#与普通情况添加监控主机不同，监控B机器的tomcat需要配置JMX接口
模板链接JMX相关的两个模板：
当JMX图标变绿即表示配置成功：
zabbix监控MySQL
A机器：zabbix服务端（192.168.234.128）
B机器：zabbix客户端（192.168.234.125）
zabbix_agent定义mysql监控的配置文件：/etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
在B机器登录mysql创建用户：
mysql> grant usage,process,replication client on *.* to zamysql@'localhost' identified by 'zamysql';
