docker run –rm -p 8086:8086 –name influxdb-local influxdb

在 pom 上添加micrometer InfluxDB 依赖了

也是时候通过application.yaml添加配置了

management:
  metrics:
    export:
      influx:
        enabled: true
        db: devjobsapi
        uri: http://127.0.0.1:8086
  endpoints:
    web:
      expose: "*"

让我们启动我们的应用程序并执行一些请求。

curl localhost:8080/jobs/github/1

一段时间后，我们可以检查数据库和包含的数据。

docker exec -it influxdb-local influx
> SHOW DATABASES;
name: databases
name
----
_internal
devjobsapi
> use devjobsapi
Using database devjobsapi
> SHOW MEASUREMENTS

process_cpu_usage
process_files_max
process_files_open
process_start_time
process_uptime
system_cpu_count
system_cpu_usage
system_load_average_1m

这真是太棒了。让我们检查访问的端点。

> SELECT*FROM http_server_requests;

非常棒！下一步是将这些指标可视化。
