MaxGauge is robust in predicting and also giving the historical data. That is very important because we can go back as many months or years to look at history, and see how the query ran and how it changes. Also the important part is that MaxGauge is not intrusive to the database, because it logs the data from the memory area rather than logging in our database. So there is no performance hit from the point of view to our database or server, so that in that way MaxGauge is very robust in getting information out.
