The Inspect Tab in the Data Aggregator function allows you to manage individual aggregation sessions, including viewing, inspecting, and deleting them. There are a few ways to access the Inspect tab, via the Data aggregator function as documented below, and via the Aggregation tab, see Aggregation Tab for more details.
Note!
The Inspect tab of the Data aggregator function is only accessible after the stream has been executed 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.
Widgets
The widgets provide a snapshot of the number of active sessions, the oldest ongoing session, and the most recently initiated session. You can hide the widgets by going to Display options and switching off the Overview widgets toggle.
Inspect tab table
The table on the Inspect tab displays the data related to the sessions.
Actions on the Inspect tab table
Under More you have the following options:
Action | Description |
|---|---|
View | Shows you the state of an aggregation session. You can copy the data if required. Example - Aggregated session data in JSON format This is an example of a JSON file sent downstream after a flush. {
"timeoutAt": "2024-10-02T14:19:48.108Z",
"createdAt": "2024-10-02T13:19:48.108Z",
"sum_fieldX": 52,
"group_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_fieldX": 52 This shows that the aggregator has summed up the value in fieldX to 52 during this session. This could refer to any fields configured in the aggregated field section in the function’s configuration. "group_fieldsA": 105 This could 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 the 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 session is flushed. This allows you to change when a timeout will happen before a session gets flushed. |
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.
