zabbix监控php-fpm的性能
zabbix通过自定义item监控php-fpm性能情况做触发器,做图形,发邮件
首先php-fpm的性能数据是要通过页面获取,所以需要在php-fpm的配置文件中添加一下语句
一般在/usr/local/php/etc/php-fpm.conf
pm.status_path = /status
重启php-fpm
在nginx的配置文件中加入页面匹配
/usr/local/nginx/conf/nginx.conf
location ~ ^/(status|ping)$
{
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
}
重启nginx
curl http://127.0.0.1/status获取性能页面
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
php-fpm状态页比较个性化的一个地方是它可以带参数,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。用了以上参数可以获得知道格式的页面
curl http://127.0.0.1/status?json
curl http://127.0.0.1/status?xml
curl http://127.0.0.1/status?html
curl http://127.0.0.1/status?full
参数full详解
pid – 进程PID,可以单独kill这个进程. You can use this PID to kill a long running process.
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
接着通过自定义item,加脚本,模板就可以通过zabbix监控性能
添加监控的shlle脚本
php-fpm_status.sh
添加zabbix-agent配置
php-fpm_status.conf
重启zabbix-agent
service zabbix-agent restart
测试
zabbix_get -s 127.0.0.1 -k slow.requests
如果没有问题导入模板
php-fpm_status.xml
