微服務(wù)異常太亂靡羡，我們?nèi)绾畏诸悾?- 簡書

Elastic APM 是基于 Elastic Stack 構(gòu)建的應(yīng)用性能監(jiān)控系統(tǒng)炎功。通過 Elastic APM 可以監(jiān)控應(yīng)用程序虎囚，收集有關(guān)請求的響應(yīng)時間邻寿、數(shù)據(jù)庫查詢伯复、高速緩存調(diào)用搞莺、外部 HTTP 請求等的詳細(xì)性能信息，這樣可以更快地查明并修復(fù)性能問題疚鲤。

Elastic APM 還會自動收集未處理的錯誤和異常锥累，錯誤主要基于堆棧跟蹤進行分組，因此可以識別出現(xiàn)的新錯誤集歇，并密切關(guān)注特定錯誤發(fā)生的次數(shù)桶略。

kibana

Kibana 是開源的分析和可視化平臺，旨在與 Elasticsearch 協(xié)同工作鬼悠，可以通過 Kibana 搜索删性、查看 Elasticsearch 中存儲的數(shù)據(jù)，此處用于可視化 Elasticsearch 中存儲的 APM 數(shù)據(jù)

搭建apm-server

APM Server 是用 Go 編寫的開源應(yīng)用程序焕窝，通常運行在專用服務(wù)器上蹬挺，默認(rèn)監(jiān)聽端口 8200 ，并通過 JSON HTTP API 從 agent 接收數(shù)據(jù)它掂，然后根據(jù)該數(shù)據(jù)創(chuàng)建文檔并將其存儲在 Elasticsearch 中巴帮。

應(yīng)用埋點APM agent

APM agent 是使用與服務(wù)相同的語言編寫的開源庫，可以像安裝其他庫一樣將它們安裝到服務(wù)中虐秋，agent 將檢測服務(wù)的代碼并在運行時收集性能數(shù)據(jù)和錯誤榕茧，這些數(shù)據(jù)緩沖一小段時間并發(fā)送到 APM server。
