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. For these cases, it is possible to go beyond the functionality of the built-in alert with a custom metric.

Normally, the query Optimiser won't consider 'bushy' plans, where both operands to a join operator could be intermediate results from other joins. This means that it won't produce good query plans for some types of query. Hints, by themselves won't do it. More powerful magic is required.
