Server Performance Advisor Tool
If looking for a free tool to do a health check on your systems, then you should take a look at the Microsoft Server Performance Advisor (SPA) tool; download version 3.0 from http://tinyurl.com/ws2012spa (you’ll need a Windows Live ID first). The goal of this tool is to help admins assess and troubleshoot any server-performance issues they may have.
Server Performance Advisor tool provides data reports and recommendations to system administrators about common configuration and performance issues, and it gathers performance-related data from various sources on servers, such as perfmon counters, WMI queries,registry entries, config files, and Windows ETW entries. Based on the server performance data that it collects, SPA can provide an in-depth look at the current server performance situation and issue recommendations about what can be improved.
SPA 3.x is designed to run on Windows Server 2012 (r2) and is suitable for SME setups, best run with environments containing < 100 servers – if you have more systems considering using an enterprise monitoring tool such as systems center operations manager (SCOM).
