You need to run the aggregated function periodically to get the calculated data log updated. Ideally, you should run the aggregation just after your data is ready, eg. shortly after a defined period. To do so, please tick “Autorun every:” check box.
Then define the period by clicking on the “…” button. You will be presented with dialog, where you can define at what time intervals to run the aggregation function.
If you need to further delay the execution of aggregation function (for example, you need to run every hour and 5 minutes), you can select “Delay execution by” and add number of minutes to delay an execution.
IMPORTANT: IF YOU DON’T RUN THE AGGREGATION FUCTION, YOU WILL HAVE NO DATA IN AGGREGATED DATA LOG
