Prometheus监控PHP应用

要监控PHP状态信息&＃xff0c;必须先配置显示PHP状态页&＃xff0c;这样Prometheus才能通过Exporter进行监控。

1、配置PHP-FPM&＃xff0c;暴露php-fpm状态信息

官方参考:https://easyengine.io/tutorials/php/fpm-status-page/
修改/usr/local/php/etc/php-fpm.conf&＃xff0c;增加以下内容

pm.status_path &＃61; /status
ping.path &＃61; /ping


目前可用于监控PHP的Exporter有三个&＃xff1a;

• https://github.com/bakins/php-fpm-exporter
• https://github.com/hipages/php-fpm_exporter
• https://github.com/Lusitaniae/phpfpm_exporter

本文只介绍前边两个

2、bakins/php-fpm-exporter监控PHP应用

bakins/php-fpm-exporter只能通过http读取PHP状态页信息&＃xff0c;需要借助nginx来提供PHP状态页数据

2.1、配置php状态页的http访问

nginx.conf

server {listen 9010; allow 127.0.0.1; #限制ipallow 192.168.28.131; #限制ipdeny all;location ~ ^/(status|ping)$ {fastcgi_pass unix:/tmp/php-cgi.sock; # unix socket#fastcgi_pass 127.0.0.1:9000; # tcpfastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;include fastcgi_params;}
}


查看状态页数据

[root&＃64; ~]# curl http://127.0.0.1:9010/status# php-fpm状态页的内容如下
pool: www
process manager: dynamic
start time: 24/Sep/2022:22:50:44 &＃43;0800
start since: 2219
accepted conn: 42
listen queue: 0
max listen queue: 0
listen queue len: 0
idle processes: 12
active processes: 1
total processes: 13
max active processes: 5
max children reached: 0
slow requests: 0


2.2、下载bakins/php-fpm-exporter

下载地址&＃xff1a;https://github.com/bakins/php-fpm-exporter
下载文件:php-fpm-exporter.linux.amd64

mv php-fpm-exporter.linux.amd64 /usr/local/php-fpm-exporter
chmod u&＃43;x /usr/local/php-fpm-exporter# php-fpm-exporter命令参数
usage: php-fpm-exporter []Flags:-h, --help Show context-sensitive help (also try --help-long and --help-man).--addr&＃61;"127.0.0.1:8080" listen address for metrics handler--endpoint&＃61;"http://127.0.0.1:9000/status" url for php-fpm status--fastcgi&＃61;FASTCGI fastcgi url. If this is set, fastcgi will be used instead of HTTP--web.telemetry-path&＃61;"/metrics"Path under which to expose metrics. Cannot be /# 运行
/usr/local/php-fpm-exporter --addr 0.0.0.0:9011 --endpoint&＃61;"http://127.0.0.1:9010/status" --web.telemetry-path&＃61;"/metrics"


查看转成Prometheus监控指标的状态页数据

[root&＃64;s2 ~]# curl http://127.0.0.1:9011/metrics


2.3、配置为系统服务

vi /usr/lib/systemd/system/php_exporter.service

[Unit]
Description&＃61;php_exporter
Wants&＃61;network-online.target
After&＃61;network-online.target[Service]
User&＃61;root
Group&＃61;root
Type&＃61;simple
ExecStart&＃61;/usr/local/php-fpm-exporter \--addr&＃61;0.0.0.0:9011 \--endpoint&＃61;http://127.0.0.1:9010/status \--web.telemetry-path&＃61;/metrics[Install]
WantedBy&＃61;multi-user.target


php_exporter服务命令

systemctl daemon-reload # 通知systemd重新加载配置文件
systemctl enable php_exporter # 设置开机启动
systemctl disable php_exporter # 取消开机启动
systemctl start php_exporter # 启动服务
systemctl restart php_exporter # 重启服务
systemctl stop php_exporter # 关闭服务
systemctl status php_exporter # 查看状态


2.4、配置防火墙

如果端口未开启&＃xff0c;需要开启相关端口

#启动防火墙
systemctl start firewalld.service
#开通端口
firewall-cmd --zone&＃61;public --add-port&＃61;9011/tcp --permanent
#重启防火墙
firewall-cmd --reload


2.5、与Prometheus集成

prometheus.yml

scrape_configs:- job_name: &＃39;PHP-FPM&＃39;static_configs:- targets: [&＃39;192.168.28.132:9011&＃39;,&＃39;192.168.28.136:9011&＃39;]


重新加载配置

curl -X POST http://127.0.0.1:9090/-/reload # prmetheus不需要登录
curl -X POST http://admin&＃64;123456:127.0.0.1:9090/-/reload # prmetheus需要登录


2.6、与Grafana集成

可视化模板&＃xff1a;https://grafana.com/grafana/dashboards/3901-php-fpm/

3、hipages/php-fpm_exporter监控php应用

3.1、下载

下载:https://github.com/hipages/php-fpm_exporter
下载文件&＃xff1a;php-fpm_exporter_2.2.0_linux_amd64

mv php-fpm_exporter_2.2.0_linux_amd64 /usr/local/php-fpm_exporter
chmod u&＃43;x /usr/local/php-fpm_exporter# 运行命令有两个
# get方式是在命令行下显示结果
sudo -u www /usr/local/php-fpm_exporter get --phpfpm.scrape-uri "unix:///tmp/php-cgi.sock;/status"# server方式是以web方式示结果
sudo -u www /usr/local/php-fpm_exporter server --web.listen-address ":9253" --phpfpm.scrape-uri "unix:///tmp/php-cgi.sock;/status"
# web方式示结果查看监控数据
curl http://127.0.0.1:9253/metrics
