监控常规的任务自然少不了 nginx 和 php-fpm 的监控,最近也是重新开始整理 zabbix,重新学习之,里面的脚本,配置文件以及模板都来源《zabbix 企业级分布式监控系统》一书,根据自身环境适当修改
一、监控 nginx server
1.1 配置 nginx 和 php-fpm
php-fpm 中 [www] 段中配置文件新增
| [www]
pm.status_path = /fpm_status.php
|
nginx 配置新增 server 段

| server {
listen 127.0.0.1:80;
allow 127.0.0.1;
deny all; # 这里两行控制权限
# 开启 nginx 状态页
location /nginxstatus {
stub_status on;
access_log off;
}
# 开启 php-fpm 状态页
location ~ ^/(fpm_status) {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
|
访问测试,确保可以查看状态信息
| curl http://127.0.0.1/nginxstatus
curl http://127.0.0.1/fpm_status.php
|
1.2 配置检测脚本和 userparameter
我配置了 agent 主动发送数据到 server 的 active 模式
首先看目录结构
| # tree /etc/zabbix/
/etc/zabbix/
├── scripts
│ ├── check_nginx_status.sh
│ └── check_phpfpm.sh
├── zabbix_agentd.conf
└── zabbix_agentd.d
├── userparameter_nginx.conf
└── userparameter_phpfpm.conf
|
下面分别对应每个文件
| UserParameter=nginx.accepts,/etc/zabbix/scripts/check_nginx_status.sh accepts
UserParameter=nginx.handled,/etc/zabbix/scripts/check_nginx_status.sh handled
UserParameter=nginx.requests,/etc/zabbix/scripts/check_nginx_status.sh requests
UserParameter=nginx.connections.active,/etc/zabbix/scripts/check_nginx_status.sh active
UserParameter=nginx.connections.reading,/etc/zabbix/scripts/check_nginx_status.sh reading
UserParameter=nginx.connections.writing,/etc/zabbix/scripts/check_nginx_status.sh writing
UserParameter=nginx.connections.waiting,/etc/zabbix/scripts/check_nginx_status.sh waiting

以上全部配置完成之后重启 agent 即可
1.3 添加模板,调用
松爷的书里提供了大量的模板,如果不想自己重写生成模板,直接拿着这个模板进行根据自身的环境修改即可
最后呈现出来的效果如下图(zatree中)
