Imagine if you are working with another DBA and he/she configures mirroring in a pair of instances without informing you... this script would show you exactly that. fluctuating Page Life Expectancy, non-zero Free List Stalls/sec and high Lazy Writes/sec indicates the buffer pool cannot handle the amount of amount of data the workload needs. was setup just to run the jobs.
