1、1.prometheus监控haproxy安装haproxyyum install haproxy -y编辑haproxy配置文件vim /etc/haproxy/haproxy.cfgglobalmaxconn 100000chroot /usr/local/haproxyuid 99gid 99daemonnbproc 1pidfile /usr/local/haproxy/logs/haproxy.pidlog 127.0.0.1 local3 infodefaultsoption http-keep-alivemaxconn 100000mode httptimeout connect
2、 5000mstimeout client 50000mstimeout server 50000mslisten stats #haproxy状态页面监听地址mode httpbind 0.0.0.0:8888frontend frontend_www_example_combind 10.0.0.150:88mode httpoption httploglog global default_backend backend_www_example_combackend backend_www_example_comoption forwardfor header X-REAL-IPoptio
3、n httpchk HEAD / HTTP/1.0balance sourceserver web-node1 10.0.0.150:8080 check inter 2000 rise 30 fall 15根据haproxy配置文件中设置的haproxy根目录地址创建haproxy根目录mkdir -p /usr/local/haproxy启动haproxysystemctl start haproxy下载安装haproxy_exporter地址cd /usr/local/src/rz haproxy_exporter-0.9.0.linux-386.tar.gztar xf haproxy
4、_exporter-0.9.0.linux-386.tar.gzcd haproxy_exporter-0.9.0.linux-386把haproxy_exporter文件复制到/usr/bin目录下cp haproxy_exporter /usr/bin启动haproxy_exporterhaproxy_exporter -haproxy.scrape-uri=http:/10.0.0.150:8888/baz?stats;csv -web.listen-address=10.0.0.150:9100 &#-haproxy.scrape-uri是haproxy状态信息采集页面地址端口号和配置
5、文件状态页面监听端口号相同状态，-web.listen-address是haproxy服务监听地址在prometheus配置文件中配置监控haproxy实例vi /etc/prometheus/prometheus.yml - job_name: haproxy #添加一个监控job名称 scrape_interval: 5s #监控采集数据时间间隔 scrape_timeout: 5s #监控采集数据超时时间 metrics_path: /metrics scheme: http static_configs: #监控静态目标配置 - targets: - 10.0.0.150:9100 l
6、abels: #监控静态目标标签 instance: haproxy:9100 重启prometheussystemctl restart prometheus刷新prometheus的target页面看到了prometheus监控haproxy的目标登录grafana创建haproxy数据源选择haproxy数据源导入haproxy监控大屏模板，模板地址2.prometheus监控nginx，参考下载nginx-module-vts模块cd /usr/local/src/git clone 重新编译nginx安装指定nginx-module-vts模块路径cd /usr/local/src/
7、nginx-1.16.1./configure -prefix=/usr/local/nginx-1.16.1/ -with-http_ssl_module -with-http_stub_status_module -add-module=/usr/local/src/nginx-module-vts/ -user=www -group=www 在nginx配置文件server标签中添加status状态页面,http标签中添加vhost_traffic_status_zonevim /usr/local/nginx/conf/nginx.confserver location /status
8、 vhost_traffic_status_display; vhost_traffic_status_display_format html; vhost_traffic_status_filter_by_set_key $uri uri:$server_name; #每个uri访问量 vhost_traffic_status_filter_by_set_key $status $server_name; #http code统计 vhost_traffic_status_filter_by_set_key $upstream_addr upstream:backend; #后端转发统计 v
9、host_traffic_status_filter_by_set $remote_port client:ports:$server_name; #请求端口统计 vhost_traffic_status_filter_by_set_key $remote_addr client:addr:$server_name; #请求IP统计http include mime.types; default_type application/octet-stream;vhost_traffic_status_zone;启动nginx/usr/local/nginx/sbin/nginx打开浏览器输入宿主机
10、ip/status访问nginx状态页面安装nginx-exporter，下载地址cd /usr/local/src/rz nginx-vts-exporter-0.9.1.linux-amd64.tar.gztar xf nginx-vts-exporter-0.9.1.linux-amd64.tar.gzmv nginx-vts-exporter-0.9.1.linux-amd64 /usr/local/nginx-vts-exporter启动nginx-vts-exporter服务，如果需要采集不同的nginx监控信息，编写不同收集的监控信息的ip地址的nginx-vts-exporte
11、r服务名称vim /usr/lib/systemd/system/nginx_vts_exporter_172.16.30.23.serviceUnitDescription=prometheus_nginx_vtsAfter=network.targetServiceType=simpleExecStart=/usr/local/nginx-vts-exporter/nginx-vts-exporter -nginx.scrape_uri=http:/172.16.20.33/status/format/json -telemetry.address 172.16.2.56:9913# 如果
12、有多个nginx监控采集页面需要收集，nginx.scrape_uri和telemetry.address都要不同Restart=on-failureInstallWantedBy=multi-user.target# nginx.scrape_uri是nginx状态服务采集信息页面地址启动nginx_vts_exportersystemctl daemon-reloadsystemctl start nginx_vts_exporternetstat -ltunp | grep nginx-vtstcp6 0 0 :9913 :* LISTEN 104725/nginx-vts-ex修改prometheus配置文件添加nginx监控节点- job_name: nginx # 添加nginx监控节点配置 static_configs: - targets: - 10.0.0.150:9913 #nginx监控节点配置nginx_vts_exporter端口号为9913重启prometheussystemctl restart prometheus刷新prometheus监控target页面看到nginx监控节点登录grafana添加nginx监控数据源导入grafana模板nginx监控指标说明n
