[Zabbix30] Nginx 監視を追加 zabbix zabbix クライアントのインストールを取得 grafana zabbi

通过Nginx的http_stub_status_module模块提供的状态信息来监控，所以在Agent端需要配置Nginx状态获取的脚本，和添加key信息等，然后在Server端配置Nginx的监控模板等。请根据自己情况调整，这里只做简单的参照。

主要是使用Github这个项目的代码 zabbix-templates

Agent端

系统是Centos6.x, Zabbix-agent是3.0版本, Nginx1.9.x 官方版本

首先要检查Nginx是否安装了 http_stub_status_module 模块，通过下面的命令可以看到编译参数。

<code>nginx <span>-V</span></code>

如果没有这个模块，还需要重新编译Nginx.

配置Nginx

Nginx 80端口的server配置增加如下的片段

<code><span>location</span> /nginx_status {
        <span>stub_status</span><span>on</span>;
        <span>access_log</span><span>off</span>;
        <span>allow</span><span>127.0.0.1</span>;
        <span>deny</span> all;
    }</code>

配置完成之后，redload nginx，然后用简单测试下

<code>>> curl http:<span>//127.0.0.1/nginx_status</span>
Active connections: <span>7</span><span>server</span> accepts handled requests
 <span>2707</span><span>2707</span><span>12528</span>
Reading: <span>0</span> Writing: <span>1</span> Waiting: <span>6</span>?</code>

zabbix-agent 配置

有3个步骤，首先是编写获取Nginx信息脚本，接着配置中增加key信息，然后重启agent 服务。

• 编写Nginx监控脚本，记住路径，后面配置需要用到。

！！注意脚本权限问题，agent运行用户要能执行。

  *) <span>echo</span><span>$ERROR_WRONG_PARAM</span>; <span>exit</span><span>1</span>;;
<span>esac</span><span>exit</span><span>0</span></code>

• agent的配置文件 /etc/zabbix/zabbix_agentd.conf 中定义了其他key的包含目录 Include=/etc/zabbix/zabbix_agentd.d/, 如果没有这个配置请自己添加下。接着在 /etc/zabbix/zabbix_agentd.d/ 目录新建一个文件 nginx-params.conf, 内容如下

<code>UserParameter=nginx[*],/usr/local/zabbix-agent/scripts/nginx-check.sh <span>"<span>$1</span>"</span></code>

• 重启agent

<code>>>> <span>/etc/init</span>.d/zabbix-agent restart</code>

Server 的Web端

首先命令行测试下刚才agent好使不，确认好用之后在web端导入模板，之后就可以给对应主机添加监控喽。

<code><span>>>></span> zabbix_get <span>-s</span><span>127.0</span><span>.0</span><span>.1</span><span>-p</span><span>10050</span><span>-k</span><span>"nginx[reading]"</span><span>0</span></code>

登录Zabbix3.0 的web界面，一次选择 Configuration > Templates ， 在主界面的右上角有个 Import 按钮，用来导入模板。

模板文件比较长留一个下载地址

导入之后就可以给主机添加监控啦。

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });
