prometheus+Grafana部署

CentOS7 下部署Prometheus+Grafana+node_exporter+blackbox_exporter監(jiān)控

image.png

一、環(huán)境

監(jiān)控端（192.168.20.13）安裝：Prometheus+Grafana

被監(jiān)控端（39.96.187.128）安裝：node_exporter+blackbox_exporter

二、軟件包下載

https://prometheus.io/download/

（統(tǒng)一下載到 /soft）

node_exporter下載：

Wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz

prometheus下載：

Wget https://github.com/prometheus/prometheus/releases/download/v2.14.0/prometheus-2.14.0.linux-amd64.tar.gz

blackbox_exporter下載：

Wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.16.0/blackbox_exporter-0.16.0.linux-amd64.tar.gz

grafana下載：

 https://dl.grafana.com/oss/release/grafana-6.5.1-1.x86_64.rpm

三、Prometheus安裝及配置

1、解壓安裝包

mkdir -p / software/prometheus

groupadd prometheus

useradd -g prometheus prometheus -d /software/Prometheus

tar -zxvf prometheus-2.14.0.linux-amd64.tar.gz

cd prometheus-2.14.0.linux-amd64/

mv * /software/prometheus/

cd /software/prometheus/

mkdir {data,cfg,logs,bin} -p

mv prometheus promtool bin/

mv prometheus.yml cfg/

chown -R prometheus.prometheus *

2、設(shè)置環(huán)境變量

vim /etc/profile

PATH=/software/prometheus/bin:$PATH:$HOME/bin

3、使變量生效

source /etc/profile

4、創(chuàng)建prometheus.service 的 systemd unit 文件

vim /etc/systemd/system/prometheus.service

內(nèi)容：

[Unit]

Description=Prometheus

Documentation=https://prometheus.io/

After=network.target

[Service]

Type=simple

User=prometheus

ExecStart=/software/prometheus/bin/prometheus --config.file=/software/prometheus/cfg/prometheus.yml --storage.tsdb.path=/software/prometheus/data

Restart=on-failure

[Install]

WantedBy=multi-user.target

5、prometheus.yml配置文件

6、啟動服務(wù)

systemctl daemon-reload
systemctl enable prometheus.service
systemctl start prometheus.service

7、運行狀態(tài)

Prometheus自帶有簡單的UI, http://192.168.20.13:9090/targets

四、node_exporter安裝及配置

1、解壓安裝包
mkdir -p /software
mkdir -p /software/prometheus
cd /soft
tar -zxvf node_exporter-0.18.1.linux-amd64.tar.gz -C /software/prometheus/
cd /software/prometheus/
mv node_exporter-0.18.1.linux-amd64 node_exporter
2、創(chuàng)建用戶
groupadd prometheus
useradd -g prometheus prometheus -d /software/prometheus
chown -R prometheus.prometheus node_exporter
3、創(chuàng)建node_exporter.service的 systemd unit 文件
vim /usr/lib/systemd/system/node_exporter.service
內(nèi)容：
[Unit]
Description=node_exporter
Documentation=https://prometheus.io/
After=network.target
[Service]
Type=simple
User=prometheus
ExecStart=/software/prometheus/node_exporter/node_exporter
Restart=on-failure
[Install]
WantedBy=multi-user.target
4、啟動服務(wù)
systemctl daemon-reload
systemctl enable node_exporter.service
systemctl start node_exporter.service

5、運行狀態(tài)

6、客戶監(jiān)控端數(shù)據(jù)匯報
訪問： http://192.168.20.13:9100/metrics，查看從exporter具體能抓到的數(shù)據(jù).如下 ：

五、blackbox_exporter安裝及配置

1、安裝
cd /software
tar -zxvf blackbox_exporter-0.16.0.linux-amd64.tar.gz -C /software/prometheus/
cd /software/prometheus/
mv blackbox_exporter-0.16.0.linux-amd64 blackbox_exporter
2、創(chuàng)建用戶
chown -R prometheus.prometheus blackbox_exporter
3、驗證安裝是否成功
cd /software/Prometheus/blackbox_exporter
./blackbox_exporter --version
![image.png](https://upload-images.jianshu.io/upload_images/26078328-e32be51c15b16633.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)

4、創(chuàng)建systemd服務(wù)

vim /usr/lib/systemd/system/blackbox_exporter.service

內(nèi)容：

Description=blackbox_exporter

Documentation=https://prometheus.io/

After=network.target

 Type=simple

User=prometheus

ExecStart=/software/prometheus/blackbox_exporter/blackbox_exporter --config.file=/software/prometheus/blackbox_exporter/blackbox.yml

Restart=on-failure

[Install]

WantedBy=multi-user.target

5、啟動服務(wù)

systemctl daemon-reload

systemctl enable blackbox_exporter.service

systemctl start blackbox_exporter.service

六、Grafana安裝及配置

1、安裝

yum localinstall grafana-6.5.1-1.x86_64.rpm

2、啟動服務(wù)

systemctl daemon-reload

systemctl enable grafana-server.service

systemctl start grafana-server.service

3、訪問WEB界面

默認賬號/密碼：admin/admin

http://192.168.20.13:3000

①add data source

②填寫信息，點擊“save&test”，如果成功，會有綠色的提示

③創(chuàng)建dashboard

④導(dǎo)入json文件

實現(xiàn)可視化我們可以直接使用現(xiàn)成的模板
硬件監(jiān)控：1-node-exporter-for-prometheus-dashboard-update-1102_rev11.json
進程監(jiān)控：2 Blackbox Exporter 0.14 for Prometheus 監(jiān)控展示看板-1575517197953.json
七、關(guān)于Prometheus的配置文件

1、注意事項
①嚴格按照格式進行縮進，否則將導(dǎo)致配置文件無效。
②job_name不能重復(fù)，否則將導(dǎo)致Prometheus啟動不了。
2、node_exporter部分的格式
例子：

  • job_name: 'node_39.96.187.128'
    static_configs:
    • targets: ['39.96.187.128:9100']
      labels:
      instance: '39.96.187.128'

效果：

3、blackbox_exporter部分的格式
例子：

  • job_name: "blackbox_39.96.187.128"
    scrape_interval: 5s
    metrics_path: /probe
    params:
    module: [tcp_connect]
    static_configs:
    - targets: ['39.96.187.128:9115','39.96.187.128:9100','39.96.187.128:9948','39.96.187.128:9941','39.96.187.128:9951','39.96.187.128:9954','39.96.187.128:9956','39.96.187.128:9936','39.96.187.128:9952','39.96.187.128:9944','39.96.187.128:9942','39.96.187.128:9947','39.96.187.128:9947','39.96.187.128:9966','39.96.187.128:9909','39.96.187.128:8901','39.96.187.128:7777']
    labels:
    group: '進程監(jiān)控'
    relabel_configs:
    - source_labels: [address]
    target_label: __param_target
    - source_labels: [__param_target]
    target_label: instance
    - target_label: address
    replacement: 39.96.187.128:9115

效果：
