Elastic APM 是基於 Elastic Stack 構建的應用性能監控系統。經過 Elastic APM 能夠監控應用程序，收集有關請求的響應時間、數據庫查詢、高速緩存調用、外部 HTTP 請求等的詳細性能信息，這樣能夠更快地查明並修復性能問題。java

Elastic APM 還會自動收集未處理的錯誤和異常，錯誤主要基於堆棧跟蹤進行分組，所以能夠識別出現的新錯誤，並密切關注特定錯誤發生的次數。linux

kibana

Kibana 是開源的分析和可視化平臺，旨在與 Elasticsearch 協同工做，能夠經過 Kibana 搜索、查看 Elasticsearch 中存儲的數據，此處用於可視化 Elasticsearch 中存儲的 APM 數據git

APM監控

搭建apm-server

APM Server 是用 Go 編寫的開源應用程序，一般運行在專用服務器上，默認監聽端口 8200 ，並經過 JSON HTTP API 從 agent 接收數據，而後根據該數據建立文檔並將其存儲在 Elasticsearch 中。web

wget https://artifacts.elastic.co/downloads/apm-server/apm-server-6.5.4-linux-x86_64.tar.gz

配置文件

[root@demo03 apm-server-6.5.4-linux-x86_64]# vi apm-server.yml 
apm-server:
  # Defines the host and port the server is listening on. use "unix:/path/to.sock" to listen on a unix domain socket.
  host: "0.0.0.0:8200"
  run:
    enabled: true
output.elasticsearch:
  # Array of hosts to connect to.
  # Scheme and port can be left out and will be set to the default (http and 9200)
  # In case you specify and additional path, the scheme is required: http://localhost:9200/path
  # IPv6 addresses should always be defined as: https://[2001:db8::1]:9200
  hosts: ["47.99.88.28:9200"]

  indices:
    - index: "apm-%{[beat.version]}-sourcemap"
      when.contains:
        processor.event: "sourcemap"

    - index: "apm-%{[beat.version]}-error-%{+yyyy.MM.dd}"
      when.contains:

    - index: "apm-%{[beat.version]}-onboarding-%{+yyyy.MM.dd}"
      when.contains:
        processor.event: "onboarding"

應用埋點APM agent

APM agent 是使用與服務相同的語言編寫的開源庫，能夠像安裝其餘庫同樣將它們安裝到服務中，agent 將檢測服務的代碼並在運行時收集性能數據和錯誤，這些數據緩衝一小段時間併發送到 APM server。數據庫
