針對 Elastic Observability 中的 Uptime 進行介紹 ，如何掌握系統的生命徵象，甚至如何從使用者體驗的角度來驗證服務的運作狀態。

* [01 - 我們要觀測的生命徵象是什麼？](https://training.onedoggo.com/tech-sharing/uncle-joe-teach-es-elastc-observability/uptime-zhang-wo-xi-tong-de-sheng-ming-zhi-xiang/wo-men-yao-guan-ce-de-sheng-ming-zhi-xiang-shi-shen-mo)
* [02 - 使用 Heartbeat 收集系統生命徵象數據](https://training.onedoggo.com/tech-sharing/uncle-joe-teach-es-elastc-observability/uptime-zhang-wo-xi-tong-de-sheng-ming-zhi-xiang/shi-yong-heartbeat-shou-ji-xi-tong-sheng-ming-zhi-xiang-shu-ju)
* [03 - 透過 Kibana 觀看心電圖及設定警報](https://training.onedoggo.com/tech-sharing/uncle-joe-teach-es-elastc-observability/uptime-zhang-wo-xi-tong-de-sheng-ming-zhi-xiang/tou-guo-kibana-guan-kan-xin-dian-tu-ji-she-ding-jing-bao)
* [04 - 使用合成監控 (Synthetics Monitor) 從使用者情境驗證服務的運作狀態](https://training.onedoggo.com/tech-sharing/uncle-joe-teach-es-elastc-observability/uptime-zhang-wo-xi-tong-de-sheng-ming-zhi-xiang/shi-yong-he-cheng-jian-kong-synthetics-monitor-cong-shi-yong-zhe-qing-jing-yan-zheng-fu-wu-de-yun-zu)
