prometheus监控springboot2.X项⽬各种默认指标,⾃定义接⼝
性能错误及其。。。
1/⽅案
通过Micrometer+actuator暴露拉取metric的端点给Prometheus，通过grafana导⼊相关优秀模板进⾏展⽰，其中增加了⾃定义指标并dashboard追加⾃定义panel的展⽰。
2/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>
</dependency>
3/配置
#Prometheus springboot监控配置
management:
endpoints:
web:
exposure:
include: 'prometheus' # 暴露/actuator/prometheus
metrics:
tags:
application: ${spring.application.name} # 暴露的数据中添加application label
4/挑选模板，推荐选⽤12856，Prometheus追加配置并重启
因为Prometheus⽬前不只⽀持基于consul，file等的服务发现，暂时只能使⽤静态配置static_configs
#抓取配置
scrape_configs:
- job_name: 'prometheus'
metrics_path: '/metrics' #默认
scheme: 'http'  #默认
#    scrape_interval: 10s    #覆盖全局
#    static_configs:
#    - targets: ['localhost:9090']
#      labels:
#        instance: xxx
#安装参考后⾯的node-exporter
- job_name: 'node-exporter'
static_configs:
- targets: ['localhost:9100']
- job_name: 'cadvisor'
static_configs:
- targets: ['localhost:9111']
- job_name: "vehicle-payment"
metrics_path: "/actuator/prometheus"
static_configs:
- targets: ["localhost:8880"]
- job_name: "vehicle-lottery"
metrics_path: "/actuator/prometheus"
5/默认监控指标
禁⽌默认指标：通过yml配置项禁⽌指标已deprecated，需要在启动类禁⽌@SpringBootApplication(exclude = {LogbackMetricsAutoConfiguration.class}，下⾯便是禁⽌logback⽇志指标后的监控项，主要还有http接⼝请求耗时，hikaricp连接
池，jvm,tomcat,jdbc，系统cpu等

6/采集⾃定义指标，如请求耗时
默认指标已有请求耗时，但不便⾃定义扩展，考虑⾃⼰采集，⾃定义指标类型有
Counter：只增不减的计数器
Gauge: 可增可减的计数器
Histogram：⾃带buckets区间分布统计，如图请求耗时（毫秒）区间：100,500,1000,3000，+Inf正⽆穷 ，不指定则默认
0.01,0.025,0.05,0.075,....7.5,10,+Inf
Summary: 客户端收集中位数，九分位数的数据指标，不指定则不统计分位数（timmer也属于summary，默认单位sencond，并统计max 值）
↓↓↓
配置收集指标的bean，⾮必须，如本案例只需要⾃动装配的registry，通过registry获取timer收集数据
