What?! Ubuntu Precise? That is an almost 10 years old release. Yes indeed but sometimes you still find some old ancestor Linux versions running on legacy systems that it is not a simple process to upgrade due to the missing development of the applications, lack of knowledge about the drivers.
Despite the oldness of your OS, it still needs to be monitored and you need to gather metrics.
