Prometheus php-fpm监控安装部署

Posted 2023-05-13 Mend。

1.进入默认php配置文件：/etc/php/7.3/fpm/php-fpm.conf 添加：pm.status_path = /fpm_status

echo "pm.status_path = /fpm_status" >>/etc/php/7.3/fpm/php-fpm.conf 

2.在nginx配置文件下面添加fpm-status location配置:/etc/nginx/conf.d/nginx-php.conf

    location ~ ^/(fpm_status|health)$ 
        fastcgi_pass unix:/run/php/php-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    

systemctl restart php7.3-fpm

systemctl reload nginx

测试一下：curl http://localhost:9090/fpm_status 有数据就ok

安装这个文件： php-fpm-exporter.linux.amd64 （官网地址：https://github.com/bakins/php-fpm-exporter/releases）

安装好了 ：

mkdir /usr/local/php-fpm-exporter/
scp root123@172.0.100.1:~/php-fpm-exporter /usr/local/php-fpm-exporter/
cd /usr/local/php-fpm-exporter/
chmod +x  php-fpm-exporter
nohup ./php-fpm-exporter --addr="172.0.100.49:9190" --endpoint="http://172.0.100.49:9090/fpm_status" >nohup.out 2>&1 &

netstat -ntpl |grep 

测试：curl 172.0.100.49:9190/metrics（也可以不用测试）

nohup /usr/local/php-fpm-exporter/php-fpm-exporter --addr="`ip a|grep global|awk -F\'[ ]+|/\' \'print $3\'`:9190" --endpoint="http://`ip a|grep global|awk -F\'[ ]+|/\' \'print \\$3\'`:9090/fpm_status" >/usr/local/php-fpm-exporter/nohup.out 2>&1 &

Prometheus 监控思科交换机---各中间件安装部署

Prometheus 监控思科交换机

因为领导比较青睐 Prometheus 开源监控，因为鄙人自身也是网络专业出身，所以便希望能用 prometheus 监控公司的交换机，公司大量的交换机在业务区，比较繁杂，虽然日常监控都可以用 Solarwinds 和 Opmanager 进行日常网络行为监控管理，但是 Solarwinds 界面比较比较有上古世纪的感觉，Opmanager 又比较卡，对服务器硬件配置稍微高了点，而且没有比开源 Prometheus 的更方便管理、进行修改配置等操作。况且现在 prometheus 有较多的公司正在使用，可搜集的资料较多，但相对来说，监控交换机的这方面， snmp_exporter 的发展就相对较为缓慢一点，不过相信我们越来越多的人使用，终究会更加完善。

Prometheus + snmp_exporter + Alertmanager + Grafana 安装部署

• 各程序说明

  • Prometheus：用于做主监控端，收集 snmp_exporter 数据信息
  • snmp_exporter：用于监控交换机设备，收集交换机数据信息
  • Alertmanager： 用于做报警端，当交换机挂掉或者CPU信息或者内存占用过高进行报警(邮件报警)，也可以对接口流量阈值进行报警
  • Grafana： 把 Prometheus 收集的数据进行比较友好的界面展示

• 使用版本

  • CentOS 7.8-2003-Minimal(4核 8G 100G)
  • prometheus 版本 2.21.0 监听 9090 端口
  • alertmanager 版本 0.21.0 监听 9093, 9094 端口
  • snmp_exporter 版本 0.19.0 监听 9116 端口，SNMP 是 UDP 协议 161 和 162 端口，所以不建议 docker 部署
  • Grafana 版本 7.2.0(docker部署) 监听 3000 端口

• 官网地址：

1.系统安装后初始步骤（优化服务器）：

yum install wget yum-utils net-tools vim unzip bash-completion -y

yum update -y

ulimit -n
sed -i "s/* soft nofile 65535/ /g" /etc/security/limits.conf
sed -i "s/* hard nofile 65535/ /g" /etc/security/limits.conf
echo "* soft nofile 65535" >>/etc/security/limits.conf
echo "* hard nofile 65535" >>/etc/security/limits.conf
ulimit -n 65535
echo "修改后文件数量"
ulimit -n

echo "优化内核参数"
echo "net.ipv4.ip_local_port_range = 1024 65535" >>/etc/sysctl.conf
echo "net.ipv4.tcp_syncookies = 1" >>/etc/sysctl.conf
echo "net.ipv4.tcp_tw_reuse = 1" >>/etc/sysctl.conf
echo "net.ipv4.tcp_tw_recycle = 1" >>/etc/sysctl.conf
echo "net.ipv4.tcp_fin_timeout = 30" >>/etc/sysctl.conf
echo "net.core.somaxconn = 20480" >>/etc/sysctl.conf
echo "net.core.netdev_max_backlog = 20480" >>/etc/sysctl.conf
echo "net.ipv4.tcp_max_syn_backlog = 20480" >>/etc/sysctl.conf
echo "net.ipv4.tcp_max_tw_buckets = 800000" >>/etc/sysctl.conf

sysctl -p

sed -i ‘s/=enforcing/=disabled/g‘ /etc/selinux/config
setenforce 0
systemctl disabled firewalld
systemctl stop firewalld
