Microservice architecture monitoring and alarming in Java framework

Java framework’s microservice architecture monitoring and alarming

In the microservice architecture, monitoring and alarming are crucial to ensuring system health and reliable operation. It's important. This article will introduce how to use Java framework to implement monitoring and alarming of microservice architecture.

Practical case: Using Spring Boot + Prometheus + Alertmanager

1. Integrate Prometheus

@Configuration
public class PrometheusConfig {

    @Bean
    public SpringBootMetricsCollector springBootMetricsCollector() {
        return new SpringBootMetricsCollector();
    }

    @Bean
    public SpringMvcMetricsFilter springMvcMetricsFilter() {
        return new SpringMvcMetricsFilter();
    }
}

2. Integrate Alertmanager

@Configuration
public class AlertmanagerConfig {

    @Bean
    public AlertReceiver alertReceiver() {
        return new HttpAlertReceiver();
    }

    @Bean
    public Alertmanager alertmanager(AlertReceiver alertReceiver) {
        return new Alertmanager(alertReceiver);
    }
}

3. Create alert rules

Define alert rules in the Prometheus configuration file:

- alert: AppServerError
  expr: sum(rate(spring_http_server_requests_seconds_count{exception=".*"}[5m])) > 0
  for: 2m
  annotations:
    summary: "App Server Error Rate High"

4. Configure the alarm receiver

Configure the alarm receiver in the Alertmanager configuration file:

route:
  receiver: slack
  routes:
  - match:
      severity: critical
    receiver: email

5. Start the application

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}

Now, when When the microservice detects an increase in error rate, Prometheus will trigger the alarm rule and send the alarm to Alertmanager. Alertmanager then sends alert notifications based on the configured receivers.

Extended scenarios

The above cases are suitable for basic monitoring and alarm scenarios. In actual applications, more complex functions may be required, such as:

  • Distributed tracing (using Zipkin or Jaeger)
  • Log analysis (using ELK or Splunk)
  • Application Performance Management (using New Relic or Dynatrace)

These functions can be achieved by integrating additional third-party tools and libraries.
