Possible to increase the limitation of events?

Hi, custom events has the following limitation

You can track your own custom events with up to twenty properties to understand the interaction between your users and the app.

Once you have started the SDK, use the trackEvent() method to track your events with properties. You can send up to 200 distinct event names. Also, there is a maximum limit of 256 characters per event name and 125 characters per event property name and event property value.

Since, unlike other analytics lib in the market, AppCenter analytics doesn't have trackView function. We can only have workaround like

    Analytics.trackEvent("VIEW-MainActivity");
    Analytics.trackEvent("VIEW-CalendarFragment");
    Analytics.trackEvent("VIEW-NoteFragment");

as oppose for real event usage purpose like

    Map<String, String> properties = new HashMap<>();
    properties.put("action", "menu");
    properties.put("label", "action_search");
    Analytics.trackEvent(TAG, properties );

Currently, we can see we will hit the limit based on above usage

• 200 distinct event
• Each event can have 20 properties

May I know the tech reason behind such limitation? Is it possible to have limit like

• 2000 distinct event
• Each event can have 200 properties

Thanks.

This is not a limitation on what we ingest. You can use export to ensure all events are exported. Please refer to the documentation on Export https://docs.microsoft.com/en-us/appcenter/analytics/export

Since the SDK itself is imposing a limit on event property count as well as the length of event names and values, we need the SDKs updated to allow higher limits, as well as supposedly the backend updated, if this limit is also imposed there.

Hi @hamswan
I found this info:
Limits
The maximum number of distinct custom events that can be tracked daily is 200. This count resets at 12 AM UTC. However, there is no limit on the maximum number of events instances sent per device.
The maximum number of event properties per event is 20. When more than 20 properties are sent, the first 20 properties are processed, and the rest are automatically dropped.
The SDK truncates event names to the first 256 characters.
The SDK truncates each property key and value to the first 125 characters.
The portal will show up the ten property values with highest count.

I confuse with your comment.

Any update on this. It would be very useful to have property values which are longer than 125 chars. E.g. I include stack traces in some reports and these are always truncated. 125 chars is just not enough to get useful information into events.

Hey @hamswan,

im basically as confused with that statement as @khoangt.
AppCenter limits the events to 200 (as stated in the documentation). Is that limitation removed, when exporting the events to AppInsights or BlobSorage? Thanks for the info!
