# Traces - 觀察應用程式的效能瓶頸

Observability 的一個核心精神，是讓我們有能力觀察系統運作的狀況，Elastic Observability 當中的 APM (Application Performance Monitoring) 就是實現 Observability 這部份精神的其中一個重要的工具，幫助我們能輕鬆的掌握系統運作的效能分析、發生異常時環節、或是在複雜的多層次架構或是微服務架構之下，服務元件之間的相依性及影響的關連，這樣的工具要如何來使用及應用，將會是這個章節的主軸。

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://training.onedoggo.com/tech-sharing/uncle-joe-teach-es-elastc-observability/traces-guan-cha-ying-yong-cheng-shi-de-xiao-neng-ping-jing.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
