四、prometheus联邦配置

一、基础环境

?

1 2 3 4 5

192.168.88.200 prometheus   # prometheus主节点 192.168.88.201 prometheus-federate1    # 联邦节点1 192.168.88.202 prometheus-federate2    # 联邦节点2 192.168.88.203 node1 192.168.88.204 node2

二、配置prometheus联邦

2.1、部署prometheus

prometheus主节点和两个联邦节点都部署prometheus

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

# 解压二进制包 root@prometheus:~# tar xf /usr/local/src/prometheus-2.30.3.linux-amd64.tar.gz -C /usr/local/ root@prometheus:~# cd /usr/local/ root@prometheus:/usr/local# ln -sv prometheus-2.30.3.linux-amd64/ prometheus 'prometheus' -> 'prometheus-2.30.3.linux-amd64/' root@prometheus:/usr/local# cd prometheus root@prometheus:/usr/local/prometheus# ls LICENSE  NOTICE  console_libraries  consoles  prometheus  prometheus.yml  promtool root@prometheus:/usr/local/prometheus#       # prometheus.service 文件 root@prometheus:~# cat > /etc/systemd/system/prometheus.service << EOF > [Unit] > Description=Prometheus Server > Documentation=https://prometheus.io/docs/introduction/overview > After=network.target > > [Service] > Restart=on-failure > WorkingDirectory=/usr/local/prometheus > ExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml > > [Install] > WantedBy=multi-user.target > EOF root@prometheus:~#       # 启动 root@prometheus:/usr/local# systemctl daemon-reload root@prometheus:/usr/local# systemctl start prometheus root@prometheus:/usr/local# netstat -tnpl | grep 9090 tcp6       0      0 :::9090                 :::*                    LISTEN      2787/prometheus    root@prometheus:/usr/local#

2.2、部署node_exporter

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

# 在node1和node2上执行以下步骤    # 二进制解包 root@node1:~# cd /usr/local/src/ root@node1:/usr/local/src# tar xf node_exporter-1.2.2.linux-amd64.tar.gz root@node1:/usr/local/src# cd node_exporter-1.2.2.linux-amd64/ root@node1:/usr/local/src/node_exporter-1.2.2.linux-amd64# ls LICENSE  NOTICE  node_exporter root@node1:/usr/local/src/node_exporter-1.2.2.linux-amd64# mv node_exporter /usr/local/bin/ root@node1:/usr/local/src/node_exporter-1.2.2.linux-amd64#       # 创建service文件 root@node1:~# cat > /etc/systemd/system/node-exporter.service << EOF > [Unit] > Description=Prometheus Node Exporter > After=network.target > > [Service] > ExecStart=/usr/local/bin/node_exporter > > [Install] > WantedBy=multi-user.target > EOF root@node1:~#       # 启动 root@node1:~# systemctl daemon-reload root@node1:~# systemctl start node-exporter root@node1:~# netstat -tnlp | grep 9100 tcp6       0      0 :::9100                 :::*                    LISTEN      2648/node_exporter root@node1:~#

2.3、配置prometheus联邦节点监控node

分别在联邦节点1上监控node1，联邦节点2上监控node2

?

1 2 3 4 5 6 7

# 监控node1 root@prometheus-federate1:/usr/local/prometheus# vim prometheus.yml ................   - job_name: "node1"     static_configs:       - targets: ["192.168.88.203:9100"] root@prometheus-federate1:/usr/local/prometheus# systemctl restart prometheus.service

?

1 2 3 4 5 6 7

# 监控node2 root@prometheus-federate2:/usr/local/prometheus# vim prometheus.yml ................   - job_name: "node2"     static_configs:       - targets: ["192.168.88.204:9100"] root@prometheus-federate2:/usr/local/prometheus# systemctl restart prometheus.service

 2.4、配置prometheus主server采集联邦节点数据

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

root@prometheus:/usr/local/prometheus# vim prometheus.yml ..........   - job_name: "prometheus-federate-1"     scrape_interval: 10s     honor_labels: true     metrics_path: '/federate'     params:       'match[]':        - '{job="prometheus"}'        - '{__name__=~"job.*"}'        - '{__name__=~"node.*"}'     static_configs:     - targets:         - '192.168.88.201:9090'     - job_name: "prometheus-federate-2"     scrape_interval: 10s     honor_labels: true     metrics_path: '/federate'     params:       'match[]':        - '{job="prometheus"}'        - '{__name__=~"job.*"}'        - '{__name__=~"node.*"}'     static_configs:     - targets:         - '192.168.88.202:9090' root@prometheus:/usr/local/prometheus# systemctl restart prometheus.service

2.5、验证prometheus server数据

 验证指标数据

 prometheus server已经可以收集两个node的指标数据了
