Logs allow you to see detailed information about how a stream execution went, search for errors, and form an understanding of the timeline of events. The Logs view provides you with the details of the events generated every time you run a stream.

Note!

There can be some cases where no logs will be displayed, for example, HTTP Functions where only errors will be shown.

Accessing the Logs view

You can access the Logs view by clicking View logs from the Stream Editor.

Alternatively, when in the Streams view, under the Actions column of a stream, click the More drop-down, then click Log.

The Logs view

You see the following information in the Logs view:

Column	Description
Timestamp	The date and time the event was generated. The timestamp is displayed in the `YYYY-MM-DD HH:mm:ss:fff` format. Note! The timestamp is displayed according to the browser’s local timezone.
Severity	Indicates the event type: Information Warning Error
Origin	The origin of the event, namely which function generated the event. This column displays ‘Engine’, ‘Data correction’, ‘Stream audit’, and ‘Tx manager’ for logs that do not come from a particular function.
Execution ID	The Execution ID of the event.
Message	The message generated for the event. Note! If the message is larger than 4000 characters, it is truncated.

Click on a log entry to expand it to view more information about the event, such as the Execution ID and the complete message of the event. Click the clipboard icon to copy details such as the Execution ID.

You can select how many rows you can view in one page. The default setting is 100 rows per page. The current logs display limit is 10000 log entries.
