zabbix监控nginx

上一篇介绍了zabbix安装，这里接着说说zabbix监控nginx

安装zabbix-agent

在实际应用中，我们server和agent部在同一机器上，所以需要分开安装，其实上一篇已经说了，在编译安装zabbix-server的时候也安装了zabbix-agent，如果只安装zabbix-agent

# 切换到zabbix解压目录
cd zabbix-3.0.3
# 编译配置
./configure --prefix=/usr/local/zabbix-agent --enable-agent
# 安装
make install

配置agent，/usr/local/zabbix-agent/etc/zabbix-agent.conf

# 在文件末尾追加下面这句话，告诉agent使用下面的脚本采集nginx数据，按照指定的格式发送给server
UserParameter=nginx.status[*],/usr/local/zabbix-agent/scripts/nginx_status.sh $1
# 配置zabbix-server地址
Server=127.0.0.1
ServerActive=127.0.0.1

添加脚本

编写脚本供agent采集nginx信息的时候调用，/usr/local/zabbix-agent/scripts/nginx_status.sh（如果没有对应的目录，手动创建）

#!/bin/bash

# Author: krish@toonheart.com
# License: GPLv2
# Set Variables
BKUP_DATE=`/bin/date +%Y%m%d`
LOG="/data/log/zabbix/webstatus.log"
HOST=127.0.0.1
PORT="80"
# Functions to return nginx stats
function active {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep 'Active' | awk '{print $NF}'
  }
function reading {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep 'Reading' | awk '{print $2}'
  }
function writing {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep 'Writing' | awk '{print $4}'
  }
function waiting {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
  }
function accepts {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| awk NR==3 | awk '{print $1}'
  }
function handled {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| awk NR==3 | awk '{print $2}'
  }
function requests {
  /usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| awk NR==3 | awk '{print $3}'
  }
# Run the requested function
$1

配置nginx

配置nginx采集运行状态信息，先检查有没有http_stub_status_module模块，如果下面显示--with-http_stub_status_module则表示编译的时候添加了该模块

在/etc/nginx/nginx.conf添加

location /nginx_status {
    stub_status on; 
}

测试nginx是否配置成功，访问http://127.0.0.1/nginx_status

Active connections: 2 
server accepts handled requests
 773 773 4747 
Reading: 0 Writing: 2 Waiting: 0 

出现类似上面内容表示nginx查看运行状态成功。

启动agent

/usr/local/zabbix-agent/sbin/zabbix_agentd -c /usr/local/zabbix-agent/etc/zabbix_agentd.conf

测试agent能不能采集数据

root@phy:/etc/php/7.0/fpm#  /usr/local/zabbix-agent/bin/zabbix_get -s 127.0.0.1 -k 'nginx.status[accepts]'
1730

如果没有报错，返回了一个数字表示agent配置成功，如果出错了，请查看/tmp/zabbix-agent.log（日志默认位置）进行解决，进行所有上面的操作以后，在zabbix-server上访问http://127.0.0.1/zabbix/index.php，就可以看到有一台主机，Monitoring->Dashboard->Host Status

在zabbix-server添加模板

添加模板

编写模板文件nginx-template.xml

<?xml version="1.0" encoding="UTF-8"?>
<zabbix_export>
    <version>3.0</version>
