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 $1
# 配置zabbix-server地址
Server=127.0.0.1ServerActive=127.0.0.1
添加脚本
编写脚本供agent采集nginx信息的时候调用，/usr/local/zabbix-agent/scripts/nginx_status.sh（如果没有对应的目录，手动创建）
#!/bin/bash # Author: krish@toonheart.com # License: GPLv2 # Set Variables BKUP_DATE=`/bin/date +%Y%m%d` LOG="/data/log/zabbix/webstatus.log" HOST=127.0.0.1 PORT="80" # Functions to return nginx stats function active { /usr/bin/curl "http://$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> <date>2015-10-25T01:29:50Z</date> <groups> <group> <name>Templates</name> </group> </groups> <templates> <template>

依次选择Configuration->Templates->Import->Browse，选择刚刚编辑的文件，点击Import
给nginx主机使用模板文件
依次选择Configuration->Host，点击nginx所在的主机（我这里是Zabbix Server），选择Templates，在输入Template App NGINX，点击“Add”，然后“Update”。
查看配置结果
在zabbix-server访问http://127.0.0.1/zabbix/index.php，如下
