A monitoring tool must provide us with an understanding of the often-complex performance patterns that databases exhibit when under load, so that we can predict how they will cope with expansion or increase in scale. It must also helps us spot the symptoms of stress and act before they become problems that affect the service, and understand better what was happening within a database when an intermittent problem started.

This metric shows Writelog wait time in ms, per elapsed second. Writelog wait types occur when the log cache is being flushed to disk. If this happens all the time, it may suggest disk bottlenecks where the transaction log is stored.

This is a good general indicator of performance problems. High stall times indicate I/O problems, which can be attributed to busy physical disks or queries that return large data sets to the client.

This metric collects the number of 8-kilobyte pages that make up the plan cache to help identify memory pressure or plan cache pollution. A sudden drop in values for this metric may indicate that the instance is under memory pressure and SQL Server had to reclaim part of the plan cache for other use.
