Memo 2: Spring Boot Actuator+Prometheus+Grafana
One: Spring Boot Actuator
Spring-boot-actuator can monitor and manage applications as they are put into production. You can choose to use HTTP endpoints or JMX to manage and monitor applications
Introducing Spring-boot-actuator into Spring boot applications
Org.springframework.boot spring-boot-starter-actuator
3.application.yml file configuration
# managementmanagement: endpoints: web: exposure: include: "*" endpoint: health: show-details: ALWAYS
4.Spring Boot Actuator built-in Endpoints
Two: Prometheus
Add Micrometer Prometheus registration to the Spring Boot application.
Io.micrometer micrometer-registry-prometheus
2.Docker pulls Prometheus image
Docker pull prom/prometheus
3. Prometheus configuration file
# my global configglobal: 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). # 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= `to any timeseries scraped from this config. -job_name: 'prometheus' # metrics_path defaults to' / metrics' # scheme defaults to 'http'. Static_configs:-targets: ['127.0.0.1 job_name 9090']-job_name:' spring-actuator' metrics_path:'/ mybatis/actuator/prometheus' scrape_interval: 5s static_configs:-targets: ['112.74.105.178spring-actuator' metrics_path']
4. Run the Prometheus container
Docker run-d-- name=prometheus-p 9090V / mnt/demo/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus-- config.file=/etc/prometheus/prometheus.yml
5. View the operation of Prometheus
Three: Grafana
Docker runs Grafana image
Docker run-d-- name=grafana-p 3000UR 3000 grafana/grafana
2. Grafana configure Prometheus data source
3. Monitoring dashboard
