中文翻译过来是哨兵的意思，官网给的解释是：Sentry is a realtime event logging and aggregation platform. At its core it specializes in monitoring errors and extracting all the information needed to do a proper post-mortem without any of the hassle of the standard user feedback loop.即 Sentry 是一个实时的事件记录和汇集的平台，它专注于错误监控以及能够自动的提取所需的事件进行处理，而不需要用户麻烦的反馈。
