Abstract: A tool for detecting potential impairment in an electronic device. The tool classifies the user input into various categories and determines some measurement, typically a rate of input per user or per time, for determining average use statistics of the electronic device. The tool then determines if a calculated measurement based on user inputs deviates from the average use statistics past some threshold level of deviation. In response to surpassing the threshold level of deviation, the tool identifies the electronic device as potentially impaired.

Abstract: An amount of a resource, such as bandwidth, needed to successfully accomplish a target Recovery Point Objective (RPO) is estimated in a data processing environment giving two or more physical or virtual data processing machines. Time-stamped samples of a usage metric for the resource are taken over a usage period. These samples are later accessed and time aligned to determine an average usage metric at defined intervals. An expected tolerance for RPO failure allows determining a first assumed amount of the resource available to achieve a target RPO that is less than might otherwise be expected. These steps can be repeated for other expected replication failure tolerances to allow a risk versus resource available trade off analysis.
