micrometer_具有InlfuxDB的Spring Boot和Micrometer第2部分：添加InfluxDB

micrometer

自从我们添加了基本应用程序以来，是时候启动InfluxDB实例了。

我们将按照之前的教程进行操作，并添加一个docker实例。

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

是时候在我们的pom上添加微米InfluxDB依赖项了

 < dependencies >  ... < dependency > < groupId >org.springframework.boot</ groupId > < artifactId >spring-boot-starter-actuator</ artifactId > </ dependency > < dependency > < groupId >io.micrometer</ groupId > < artifactId >micrometer-core</ artifactId > < version >1.3.2</ version > </ dependency > < dependency > < groupId >io.micrometer</ groupId > < artifactId >micrometer-registry-influx</ artifactId > < version >1.3.2</ version > </ dependency >  ...  </ dependencies >

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: "*"

让我们启动应用程序并执行一些请求。
一段时间后，我们可以检查数据库和其中包含的数据。

 docker exec -it influxdb- local influx  > SHOW DATABASES;  name: databases  name  ----  _internal  devjobsapi  > use devjobsapi  Using database devjobsapi  > SHOW MEASUREMENTS  name: measurements  name  ----  http_server_requests  jvm_buffer_count  jvm_buffer_memory_used  jvm_buffer_total_capacity  jvm_classes_loaded  jvm_classes_unloaded  jvm_gc_live_data_size  jvm_gc_max_data_size  jvm_gc_memory_allocated  jvm_gc_memory_promoted  jvm_gc_pause  jvm_memory_committed  jvm_memory_max  jvm_memory_used  jvm_threads_daemon  jvm_threads_live  jvm_threads_peak  jvm_threads_states  logback_events  process_cpu_usage  process_files_max  process_files_open  process_start_time  process_uptime  system_cpu_count  system_cpu_usage  system_load_average_1m

太棒了让我们检查访问的端点。

 > SELECT*FROM http_server_requests;  name: http_server_requests  time               count exception mean       method metric_type outcome status sum        upper      uri  ----               ----- --------- ----       ------ ----------- ------- ------ ---        -----      ---  1582586157093000000 1 None 252.309331 GET   histogram  SUCCESS 200 252.309331 252.309331 /actuator  1582586157096000000 0 None 0 GET   histogram  SUCCESS 200 0 2866.531375 /jobs/github/{page}

太棒了！下一步将是可视化那些指标。
