每个工作日，一家大型企业都可能存在一两件优先级为 1 级的事件，五六件优先级为 2 级的事件和百来件优先级为 3 级的事件。试想一下，如果公司所有支持人员都要收到每个事件的通知……不想了，我好方！还能不能愉快的工作了？然而，这样的事情每天都在各个企业里上演。然而支持团队并无权处理所有事件！他们却需要反复地处理各个事件，如果全球各地的支持团队都如此，想想这总共得浪费多少时间和多少叠 money 呀！ 2012 年全球第一家 ITOA 企业 Splunk 的上市，人们才有了更为有效的方法解决上述问题。 首先我们先科普下 ITOA 究竟是为何物， Wikipedia 如是说 ： Definition: IT Operations Analytics (ITOA) (also known as Advanced Operational Analytics, or IT Data Analytics) technologies are primarily used to discover complex patterns in high volumes of often "noisy" IT system availability and performance data.
