New Custom Metric: Long Running Job

SQL Monitor’s Job duration unusual alert is a powerful tool for keeping track of most jobs in your SQL Server environment. It works by comparing the running time of any job instance against the median for that job, and identifying when a variation in the job duration could hint at a performance problem. However, if your environment contains big jobs whose durations vary by several orders of magnitudes, it can be tricky to specify what kind of variation is expected and what would be unusual.

How can I deal with the use of these three roles?
