When do the log files in IBM MobileFirst Analytics get created?

Question

I can download logs file via analytics console > Devices > Device Search > Device Information > Download Logs

I'd like to know when do the log files get created and updated?

Answer 1

Logs from an application on a device (or any other MobileFoundation supported environment) are only sent to the server, and therefore to the Analytics data store, when the application logs are explicitly sent via API call:

WL.Logger.send();  // JavaScript
[OCLogger send];  // objective-c (iOS)
Logger.send();  // Java (Android)

These functions are called automatically after your application calls WLClient.connect or WLClient.invokeProcedure. If your app calls neither of these, you must explicitly call send(). It's a bit confusing, I know, but that's the current implementation.

Answer 2

The newer data updated in the logs file until the queue size are fullfiled.

We must setting the wl.analytics.queue.size in the server.xml Sets the number of individual analytics data that each queue can hold. The total number of analytics data that the server can hold at one time before it begins to drop data is (wl.analytics.queues * wl.analytics.queue.size)

Answer 3

The logs get created once a device has registered in the server and mention of this arrived to the analytics database, which you can then view in the Analytics console. Once you click the download button the file gets generated with the latest available data and is downloaded.

Explain your question further so a fuller answer could be provided.
