spring boot监控之prometheus配置

1，spring boot工程引入jar包

compile ‘org.springframework.boot:spring-boot-starter-actuator‘
compile ‘io.micrometer:micrometer-core:1.3.5‘
compile ‘io.micrometer:micrometer-registry-prometheus:1.3.5‘

2，修改spring boot工程配置

management:
  server:
    port: 10091
  endpoints:
    web:
      exposure:
        include: ‘*‘

3，监控代码示例

 Counter counter = Metrics.counter("counter", "tag-1", "tag-2");
 counter.increment();

4, 启动Spring boot工程

启动后访问http://localhost:10091/actuator，应该能看到返回很多链接，如能看到http://localhost:10091/actuator/prometheus, 说明正确。

5，安装配置prometheus

下载安装后后，修改prometheus.yml

# 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: /actuator/prometheus
    # scheme defaults to ‘http‘.

    static_configs:
    - targets: [‘localhost:10091‘]

6, 启动prometheus，查看运行效果
