Check Xenta Trend Log impact on Vista performance

Issue

Trend logs that are stored in a Xenta Programmable must be uploaded to the Vista Server at certain intervals/when certain capacities of memory are reached. If there are many Xenta Trends all trying to upload to the server simultaneously, it can bog down the network and cause communication problems. This utility will help diagnose these situations by providing a summary of all trends and flagging any areas of concern.
