If possible to trigger alerts after compared the current values with the moving average or pervious values with mutliple factors.
For example, when using NPM or APM to monitor system statistics, e.g. CPU loading, Memory, Disk Spacing or other application factors. If the current value is suddenly increased to 1.5 times or 2 times compared with moving average or pervious values, the system will be able to trigger some alerts to give warning to administartors as they may be signals for coming problems.
This isn't possible now, but it's an existing feature request.
