Ever get the question from your end user “Is the database down?” That is one question a DBA hates to hear or even worse, to find out is true. This paper will look at how to use Enterprise Manager to monitor your environment. The topics we will look at are how to create a metric, build rules, create notification methods, and deploy/manage many targets. By the end of the paper, hopefully you will have enough knowledge to start building a monitoring framework or at least be comfortable enough to navigate around and start digging deeper.
