Note!

The Inspect tab of the Data aggregator function is only accessible after the stream has been executed at least once. if you have to have active sessions. This means that a stream with a Data aggregator function needs to be run at least once.

To navigate to the Inspect tab, double-click on the Data aggregator function icon from the stream editor canvas, then click Inspect at the top right of the page.

Example - Aggregated session data in JSON format

This is an example of a JSON file sent downstream after a flush.

Code Block
{
    "timeoutAt": "2024-10-02T14:19:48.108Z",
    "createdAt": "2024-10-02T13:19:48.108Z",
    "sum_sheetsfieldX": 52,
    "printerIdgroup_fieldsA": 105,
    "month_timestamp": "2024-09"
}

"timeoutAt": "2024-10-02T14:19:48.108Z"

This indicates the exact time when the system flushed the aggregated data. The data was flushed (sent downstream or processed further) based on a timeout at this specific timestamp.

"createdAt": "2024-10-02T13:19:48.108Z"

This marks the start time of the aggregation session, showing when the session was created. It indicates that this session ran for exactly one hour before the timeout occurred and the data was flushed.

"sum_sheetsfieldX": 52

This shows that the aggregator has summed up 52 "sheets" the value in fieldX to 52 during this session. This could refer to the total number of sheets processed, for example, in this printing as a service scenario, or any other unit of data being aggregated. You can use this to confirm the total count processed during the session."printerIdany fields configured in the aggregated field section in the function’s configuration.

"group_fieldsA": 105

This is the identifier for the printer (or another entity) associated with this aggregation. It shows which printer's data was aggregated in this sessioncould be any field that has been used to group the data during aggregation. It can be set by selecting fields in Group fields in the function's configuration.

"month_timestamp": "2024-09"

This field represents a monthly aggregation period, showing that the processed data corresponds to September 2024the aggregation period. this is based on the date/time configured in Group fields in the aggregator function’s configuration.

Note!

These metadata fields can be used when creating custom scripts for aggregated data. See, Metadata, at the bottom of this page for more details.

Edit Timeout

Edit the timeout date and time on a session before a timeout window has passedsession is flushed. This allows you to change when a timeout will happen before a session gets flushed. This allows you to extend or adjust the time window during which the session remains open, and after modifying the timeout, you can queue the data for reprocessing based on the new timeout.

Delete

Delete the session. A warning message and confirmation dialogue will pop up.

Note!

You cannot delete a solution, stream, or data aggregator function that has active aggregation sessions. You must first delete the aggregation sessions and then delete the functions, streams, and solutions they were a part of.

...

You can filter the aggregated sessions based on the following:

Filter panel fields

Tip

Hint!

When you have set a filter, the Filters Applied label is displayed. Click on the Hide filter button to hide the Filter options.

Refresh data

Use this button to update and view the most current state of the aggregation sessions or data being displayed.

Metadata

There may be instances where you want to apply certain rules to aggregated data, such as applying a discount or adjusting values based on specific business rules. You can achieve this by using the Script function. If you need to reference metadata from aggregated sessions, such as the number of records or timestamps, you can access it using the meta-variable as described in Supported Variables/APIs.

Info

Example- metadata for an aggregated session

This example shows a JSON object representing metadata about a Data Aggregator function. It shows an aggregation session, including details about the events processed and how the data was flushed.

Code Block
{"origin":"Data_Aggregator","count":7,"flushType":"TIMEOUT","firstEvent":"2022-04-08T17:35:53.239Z","lastEvent":"2022-04-08T17:38:17.315Z","lastCall":false}

Property name 

Description

origin

This indicates that the data comes from the Data Aggregator component of the stream

count

Number of aggregated records

flushType

The reason for the session being flushed out. Shows any of the values: ALL_FILES, EACH_FILE, TIMEOUT, and CONDITION. During preview, the value will be empty.

firstEvent

Date and time of the first aggregated record in the session

lastEvent

Date and time of the last aggregated record in the session

lastCall

This indicates that this flush is not the final flush of the stream. There may still be more data to process, and additional flushes will happen later.
