在Github中stars數最多的Go日誌庫集合

在Go語言世界中，日誌庫並不像Java世界那裏有一個具備統治力的日誌庫。在作新項目技術選型的時候，不免會遇到日誌庫的選擇問題，今天筆者就爲你們介紹一下在Github中stars數最多的Go日誌庫。

logrus是我已知的Go語言日誌庫中在Github中stars數最多的日誌庫，功能強大，性能也不錯。另外值得一提的是logrus的一個fork庫gogap/logrus，能夠配置輸出到文件和graylog日誌系統，基礎的level、調用鏈、行號，文件切分都有，特點是結構化日誌能夠被統計和索引，藉助graylog就能夠作日誌分析，不過這個庫好久沒有維護了。

zap是Go中一個快速，結構化，分級日誌庫，Uber出品。可以激活強大的ad-hoc分析, 靈活的儀表板, 其功能超過其餘工具ELK, Splunk, 和 Sentry. 全部日誌消息都是JSON-serialized。也是目前筆者使用的日誌庫之一。

zerolog也是一款性能至關好的日誌庫，有趣的是zerolog和zap都在自家的Github庫首頁中的性能對比數據裏戰勝了對方：）

Seelog是一個原生Go日誌庫,提供了靈活的異步調度、過濾和格式化。這也是筆者較早期使用的Go日誌庫之一。

blog4go是高性能日誌庫。創新地使用「邊解析邊輸出」方法進行日誌輸出，同時支持回調函數、日誌淘汰和配置文件。能夠解決高併發，調用日誌函數頻繁的情境下，日誌庫形成的性能問題。

有一些Github庫star數並很少，可是功能卻不少，例如mkideal/log、go-log、alog等就是功能十分齊全的日誌庫，簡單易用。還有一些是對開發工程中有些小幫助的庫，例如happierall/l。

下面是我整理的Go語言日誌庫列表，你們能夠依據本身項目的實際需求選擇（若是您還有好用的Go日誌庫推薦，請留言分享）。
