Gaussian Filter

the gaussian filter processor is a simple gaussian digital filter gaussian filter overview first, the mean, standard deviation and variance of a window of values is calculated coefficient is calculated by the formula 1/ {squareroot(2 pi) deviations} exponential part is calculated by the formula exp{ (1/2) (current mean)^2 / (dev)^2 } multiplying those values gives the gaussian function, and then filtered value is obtained the timer interval parameter is useful if the connected input tag is currently not polling, but you still want this kpi to publish a value every few seconds, defined by the aforementioned timer if you know your input is going to publish at the expected interval, it is better to disable this timer by entering 0 in the field gaussian filter parameters parameters details window size this parameter specifies the window in which the gaussian filter calculates its values the window size represents the number of seconds over which the gaussian filter operates timer interval timer in milliseconds if no event, use this timer to keep displaying the output continually enter zero to disable pass through value the pass through value parameter enables you to specify how anomalous data should be handled note when creating an analytics flow with gaussian filter processor, refer the use the gaussian filter function docid\ ofvnnntrlwlwfh5cosweg guide for more details
