      Description

      For visualization, raw data maybe overwhelming the rendering device. Some kind of low pass filter needs to be implemented to visual monitoring data.

      One example of low pass filter is described in:

      Similar algorithm can be implemented in Chukwa REST API for serving daily monitoring data.
