REDUCING IMPACT OF COLLECTING SYSTEM STATE INFORMATION
A system and method intelligently collect performance data from managed electronic devices. A machine learning model (e.g. linear time series forecasting) is used to predict a future workload for each of a selection of devices, and a regression analysis is used to predict how long is likely to be required to collect performance state from each component of each device. These data are then mapped together to predict future overall idle periods of each device, together with components whose performance data may be collected during those periods. The components are grouped in batches according to a relevance order that itself may be determined by applying a machine learning model such as k-nearest neighbors. Then, performance data are collected according to the batches. In this way, performance data may be collected in chunks while avoiding a negative impact on execution of the primary functions of the managed devices.
