prometheus+grafana监控体验

先上pom依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
            <version>1.1.3</version>
        </dependency>

再上配置

    @Bean
    MeterRegistryCustomizer<MeterRegistry> configurer(@Value("${spring.application.name}") String applicationName) {
        return (registry) -> registry.config().commonTags("application", applicationName);
    }

management.endpoints.web.exposure.include=*
management.metrics.tags.application=${spring.application.name}

# 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'.

    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'xf_aa'
    scrape_interval: 5s
    metrics_path: '/actuator/prometheus'
    static_configs:
    - targets: ['localhost:8082']
  - job_name: 'tomcat'
    scrape_interval: 5s
    static_configs:    
    - targets: ['localhost:30013']
      labels:
        appname: 'testjmx'

启动命令添加

-javaagent:e:/es/jmx_prometheus_javaagent-0.12.0.jar=30013:e:/es/jar.yml

jar下载地址：https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.12.0/jmx_prometheus_javaagent-0.12.0.jar

自定义监控

    @Autowired
    PrometheusMeterRegistry registry;

    @Bean
    public Counter getCounter() {
        Counter counter = Counter.builder("goods_rank_sync_count").tags("xf_status", "success")
                .description("Number of successful goods rank sync").register(registry);
        return counter;
    }

在业务相关的地方注入Counter，调用counter.increment()

备注：

grafana配置使用id为8563是jmx的，4701是jvm相关的
