[jira] [Created] (EDGENT-246) Aggregate Function and Console
Brandon Swink created EDGENT-246:
------------------------------------
Summary: Aggregate Function and Console
Key: EDGENT-246
URL: https://issues.apache.org/jira/browse/EDGENT-246
Project: Edgent
Issue Type: Task
Components: Analytics
Affects Versions: 0.4.0
Environment: Demonstration (Meetup)
Reporter: Brandon Swink
Fix For: 0.4.0
I would like to use this function in a demo for my meetup in the next few weeks and my modification seems to have a compile error on the aggregate. I would also like to couple it with the Edgent Console. Do I need to modify this code to include the console or do I need to trigger using another component?
//*****CODE
// Create a window on the stream of the last 50 readings partitioned
//TWindow<JsonObject,JsonElement> sensorWindow = sensors.last(50, j -> j.get("ts"));
TWindow<JsonObject,Integer> sensorWindow = sensors.last(50, unpartitioned());
// Aggregate the windows calculating the min, max, mean standard deviation and Slope across each window independently.
sensors = JsonAnalytics.aggregate(sensorWindow,"cpuTemperature","cpuVoltage", MIN, MAX, MEAN, STDDEV, SLOPE);
