Question

我正在尝试在Spring引导应用程序上设置Prometheus监视，但出现错误：Get https://example.com:8080/actuator/prometheus: EOF

我的设置

application.yml

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    metrics:
      enabled: true
    prometheus:
      enabled: true
  metrics:
    export:
      prometheus:
        enabled: true

Prometheus config

global:
  scrape_interval:     5s # Set the scrape interval to every 5 seconds.
  evaluation_interval: 5s # Evaluate rules every 5 seconds.

scrape_configs:
  - job_name: 'app'
    metrics_path: '/actuator/prometheus'
    scheme: https
    static_configs: 
      - targets: ['example.com:8080']

现在，当浏览到actuator/prometheus时，我可以看到数据：

# HELP hikaricp_connections_usage_seconds Connection usage time
# TYPE hikaricp_connections_usage_seconds summary ....
....

但是在Prometheous目标屏幕上，我可以看到正确的网址，但带有指定的错误。

我正在使用Docker运行Prometheus。

level=info ts=2018-08-14T19:10:59.6844594Z caller=main.go:603 msg="Loading   configuration file" filename=/etc/prometheus/prometheus.yml
level=info ts=2018-08-14T19:10:59.686749Z caller=main.go:629 msg="Completed loading of configuration file" filename=/etc/prometheus/prometheus.yml
level=info ts=2018-08-14T19:10:59.6867898Z caller=main.go:502 msg="Server is ready to receive web requests."

Answer 1

Prometheus目标屏幕显示EOF错误，表明prometheus.yml文件中有问题

在prometheus配置文件中更改抓取配置

- job_name: 'person-app' metrics_path: '/actuator/prometheus' static_configs: - targets: ['example.com:8080']

目标应包括您的主机名，而不是URL。更改配置文件后重新启动Prometheus

用于更新的yml文件

方案标签应位于static_configs上方。正确的声明应该是

job_name: 'person-app' metrics_path: '/actuator/prometheus' scheme: 'https' static_configs: - targets: ['example.com:8080']

Answer 2

我创建了a sample to reproduce your issue，但失败了。请注意，样本位于so-51765772上，而不是master和I changed scheme and target from your Prometheus configuration上，以便于重现，如下所示：

global:
  scrape_interval:     5s # Set the scrape interval to every 5 seconds.
  evaluation_interval: 5s # Evaluate rules every 5 seconds.

scrape_configs:
  - job_name: 'app'
    metrics_path: '/actuator/prometheus'
    scheme: http
    static_configs: 
      - targets: ['localhost:8080']

我想问题可能出在其他地方。因此，如果您可以使此示例无法按您所看到的方式失败，那么我可以再看一遍。
