Grafana+Prometheus打造springboot監控平台

1. 環境

springboot 1.5.10.RELEASE

Grafana 5.4.2

Prometheus 2.6.0

jdk 1.8

2.通過micrometer與springboot應用和prometheus的集成

在項目pom.xml中添加如下依賴

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
<version>1.5.4.RELEASE</version>
</dependency>
<!--<dependency>
<groupId>io.prometheus</groupId>
<artifactId>simpleclient_spring_boot</artifactId>
<version>0.5.0</version>
</dependency>-->
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-prometheus</artifactId>
<version>1.1.1</version>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-spring-legacy</artifactId>
<version>1.1.1</version>
</dependency>

gradle.build中增加如下：

    compile 'io.micrometer:micrometer-registry-prometheus:1.1.1'
    compile 'io.micrometer:micrometer-spring-legacy:1.1.1'

在 application.yml中添加如下配置（因為是測試，所以我把所有端點都暴露了，生產環境自行選擇打開端點）

management:
  endpoints:
    web:
      exposure:
        include: health,info,env,prometheus,metrics,httptrace,threaddump,heapdump,springmetrics
    jmx:
      exposure:
        include: '*'
    shutdown:
      enabled: false
  metrics:
    distribution:
      percentiles-histogram[http.server.requests]: true
  security:
    enabled: false

啟動項目，在eclipse中可以看到接口 /prometheus 如下圖

 

通過瀏覽器查看prometheus.json文件如下圖：

至此，應用側的prometheus client的工作已經完成。

 

3.安裝prometheus

下載你想安裝的prometheus版本，地址為download prometheus

我下載的是prometheus-2.6.0.linux-amd64.tar.gz 

解壓

tar xvfz prometheus-*.tar.gz
cd prometheus-*

在某目錄創建 prometheus.yml文件內容如下

# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    metrics_path: /prometheus
    static_configs:
    - targets: ['10.200.110.100:8082']#此處填寫 Spring Boot 應用的 IP + 端口號

注意：metrics_path:和targets的配置。

啟動

./prometheus --config.file="prometheus.yml" 

在Status->Targets頁面下，我們可以看到我們配置的Target，它們的State為UP ,如下圖

 

至此，prometheus和springboot已經連接成功。

4.安裝Grafana

使用的是ubuntu 16.04TLS，所以找到官網相對應的Ubuntu方式，這是官網的鏈接地址：https://grafana.com/grafana/download?platform=linux

wget https://dl.grafana.com/oss/release/grafana_5.4.2_amd64.deb 
sudo dpkg -i grafana_5.4.2_amd64.deb 

啟動grafana
方式一、Start Grafana by running:

sudo service grafana-server start
sudo update-rc.d grafana-server defaults //設置開機啟動（可選）

方式二、To start the service using systemd:

systemctl daemon-reload
systemctl start grafana-server
systemctl status grafana-server
sudo systemctl enable grafana-server.service //設置開機啟動

 

grafana添加數據源，配置如下

 

 6.創建看板

grafana支持很多種看板，你可以根據不同的指標生成圖表，

 

因為圖表的配置比較復雜，這里沒有深入的研究，而是選用了大神 們做好的模板，對接數據源進行展示

 https://grafana.com/dashboards 在這里可以搜索不同的模板

選擇一個你想要的點擊去，然后復制id

 

打開下圖頁面，並將id粘貼進去，光標離開輸入框，會自動加載模板配置

 

接着選datasource：

 

然后選取數據源，點擊import按鈕，完成模板添加

看數據都是空的，因為這個是springboot2.x的。要換成springboot1.x的，如下圖：

結果：

完成。

多個應用的配置，如下配置兩個微服務應用：

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'service-productor' # metrics_path defaults to '/metrics' # scheme defaults to 'http'. metrics_path: /prometheus static_configs: - targets: ['10.200.110.100:8082'] - job_name: 'service-consumer' # metrics_path defaults to '/metrics' # scheme defaults to 'http'. metrics_path: /prometheus static_configs: - targets: ['10.200.110.100:8081']

 重啟prometheus后，再刷新target頁面：
