Hi, Can somebody give direction on the following please. I wish to quantify workload and throughput of my SQL Server box containing one user database and want to make a statement like "The throughtput of my server is X and the workload is varying between Y and Z within last 3 months. Based on the current trend in workload we need to think of additional resources in W months". Is this possible with perfmon counters data collected historically? Thanks in advance of any response.
