nginx status 监控扩展包 https://github.com/oscm/zabbix/tree/master/nginx
从 localhost 收集 nginx 状态信息
server {
listen 80;
server_name localhost;
location /status {
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
}
配置 zabbix_agentd
创建配置文件 /etc/zabbix/zabbix_agentd.d/userparameter_nginx.conf 内容如下：
############################################################ # Redis - statistics # # Author: Neo Chen <netkiller@msn.com> # Website: http://www.netkiller.cn ############################################################ # Discovery # Return Redis statistics UserParameter=nginx.status[*],/srv/zabbix/libexec/nginx.sh $1
安装数据采集脚本，请使用 nginx.sh
mkdir -p /srv/zabbix/libexec
vim /srv/zabbix/libexec/nginx.sh
chmod +x /srv/zabbix/libexec/nginx.sh
# /srv/zabbix/libexec/nginx.sh
Usage /srv/zabbix/libexec/nginx.sh {check|active|accepts|handled|requests|reading|writing|waiting}
# /srv/zabbix/libexec/nginx.sh accepts
82
# systemctl restart zabbix-agent.service
使用 zabbix-get 工具从 Zabbix Server 链接 Zabbix Agent 测试是否正常工作
Test Agent # yum install -y zabbix-get # zabbix_get -s <agent_ip_address> -k 'nginx.status[accepts]' 109
最后进入Zabbix Web界面导入模板 zbx_export_templates.xml
Import file: choice xml file click "import" button Imported successfully 表示成功导入

php-fpm 可以带参数json、xml、html并且前面三个参数可以分别和full做一个组合。
status 详解 ----- pool – fpm池子名称，大多数为www process manager – 进程管理方式,值：static, dynamic or ondemand. dynamic start time – 启动日期,如果reload了php-fpm，时间会更新 start since – 运行时长 accepted conn – 当前池子接受的请求数 listen queue – 请求等待队列，如果这个值不为0，那么要增加FPM的进程数量 max listen queue – 请求等待队列最高的数量 listen queue len – socket等待队列长度 idle processes – 空闲进程数量 active processes – 活跃进程数量 total processes – 总进程数量 max active processes – 最大的活跃进程数量（FPM启动开始算） max children reached - 大道进程最大数量限制的次数，如果这个数量不为0，那说明你的最大进程数量太小了，请改大一点。 slow requests – 启用了php-fpm slow-log，缓慢请求的数量 full详解 ----- pid – 进程PID，可以单独kill这个进程. state – 当前进程的状态 (Idle, Running, …) start time – 进程启动的日期 start since – 当前进程运行时长 requests – 当前进程处理了多少个请求 request duration – 请求时长（微妙） request method – 请求方法 (GET, POST, …) request URI – 请求URI content length – 请求内容长度 (仅用于 POST) user – 用户 (PHP_AUTH_USER) (or ‘-’ 如果没设置) script – PHP脚本 (or ‘-’ if not set) last request cpu – 最后一个请求CPU使用率。 last request memorythe - 上一个请求使用的内存
