The discovery of Oracle engineers

Although managers of data centers for a long time use heat maps to help determine the best position for the group server and refrigeration units, this mode of visualization can also be used for better understanding of the latency of the system, considered one of the engineers at Oracle. Presentation of the latency of the map warming is an effective way to identify some features that would otherwise have been missed, according to Brendan Gregg, software engineer at Oracle. However, he points out that although this method provides insight into where the problem occurs it can not always have to explain why there is a specific problem with latency.
