Understanding overhead of performance management is central to ensure adequate results and minimum impact on the application. However not everything people believe to know about overhead is necessarily true. In this article common myths and truth about performance overhead measurement are discussed and explained. Alois Reitbauer from dynaTrace writes:
The same is true for performance measurement. In order to collect our measurements we have modify the system and execute additional code. This code execution consumes system resources which we perceive as overhead. This means that we have to test overhead before using a performance management solution. We at dynaTrace recommend to this as part of the application roll-out. During application roll-out overhead is tested and optimized in case it is too high. Additionally we have to plan for some measurement overhead. If we are already utilizing our systems to their limits, adding performance measurement will simply not be possible.
