Calculate Time Since User's Last Session in Mixpanel
kapa.ai Is it possible to calculate the time elapsed since a user's last session up to the current moment in Mixpanel?
kapa.ai Is it possible to calculate the time elapsed since a user's last session up to the current moment in Mixpanel?
I'm sorry, but the knowledge sources do not explicitly mention a built-in way in Mixpanel to calculate the time elapsed since a user's last session up to the current moment. While Mixpanel provides session events (Session Start and Session End) and properties like "Session Duration (Seconds)" for analyzing session lengths and aggregating session data, there is no direct reference to a feature or formula for calculating the time since a user's last session ended to the present time.You may be able to approximate this by exporting session data and performing this calculation externally, but this workflow is not described in the provided documentation. If you need to perform this calculation within Mixpanel, you might consider reaching out to Mixpanel support or checking for updates in their documentation for any new features that support this use case.For reference on available session metrics and properties: Sessions: Compute sessions based on existing event data.

Based on the knowledge sources, Mixpanel’s custom properties feature allows you to create new properties using formulas, including date/time calculations. You can use functions like TODAY() to get the current time and compare it to a property such as the session end time (e.g., $time) to compute the difference. This is similar to the documented use case of calculating the number of days between two date properties or between a date property and the current time using TODAY().For example, you could define a custom property as: LBKSTODAY() - $timeLBKSThis would give you the time elapsed since the session end (assuming $time represents the session end timestamp). The documentation specifically mentions using TODAY() for such calculations, like finding the difference between a date property and the current date/time to compute things like "days active since registration" Custom Properties: Calculate new properties on the fly.However, the documentation does not provide a step-by-step example for sessions specifically, so while the approach is supported in principle, you may need to ensure that you are referencing the correct session end property in your custom property formula.In summary:
Yes, it is possible to calculate the time since the last session ended by creating a custom property that subtracts the session end time from the current time using the TODAY() function, as long as you have access to the session end timestamp property in your events Custom Properties: Calculate new properties on the fly.

Based on the knowledge sources, Mixpanel allows you to create custom properties using formulas, including date/time calculations with functions like TODAY(). You can create both custom event properties and custom user properties using the property builder. However, the documentation does not explicitly state that you can reference a session end time (such as $time from a Session End event) as a user property in a way that always reflects the user's most recent session end across all their events.Custom user properties typically describe user-level attributes (e.g., demographic info, signup date) and are joined to events based on the Distinct ID. While you can create a custom user property using a formula, the sources do not confirm that you can dynamically set this property to always reflect the latest session end time for each user, as session end times are event-level data and may not be automatically promoted to the user profile level without additional processing or manual updates Custom Properties: Calculate new properties on the fly Property-reference: Types of Properties in Mixpanel.In summary:
You can create custom user properties with formulas, but the knowledge sources do not confirm that you can directly reference the latest session end time as a user property for use in a formula like TODAY() - $time. This may require additional steps or manual updates not described in the documentation.

Based on the knowledge sources, Mixpanel allows you to create both custom event properties and custom user properties using formulas in the property builder. However, the documentation does not explicitly state that you can automatically pass the value of a custom event property to a custom user property.Custom event properties are calculated and available in the context of events, while custom user properties are calculated in the context of user profiles. There is no mention of a built-in mechanism to automatically sync or transfer a calculated custom event property value to a user property within Mixpanel’s custom property system. The sources describe how user profiles and events are joined at query time, but not how to promote or transfer values between custom event and user properties automatically Custom Properties: Calculate new properties on the fly Property-reference: Types of Properties in Mixpanel.In summary: The knowledge sources do not provide information confirming that you can pass a custom event property value to a custom user property automatically within Mixpanel. If this functionality is critical, you may need to update user properties programmatically via the API or SDKs, but this workflow is not described in the provided documentation.

kapa.ai If the WHC frequency is set to "hourly" but there are no entries in the sync history that have been running or pending for more than 36 hours, should we assume that the data is not coming in properly? Aside from the sync history, is there any other way to check whether the sync is working correctly?

If your Warehouse Connector (WHC) sync frequency is set to "hourly" but you do not see any entries in the sync history that have been running or pending for more than 36 hours, this could indicate that data is not being synced as expected. The sync history is the primary place to monitor the status and recency of your sync jobs.Aside from the sync history, the knowledge sources do not mention any additional built-in Mixpanel tools or views specifically for monitoring the operational status of Warehouse Connector syncs. However, you can: - Check your data in Mixpanel reports (such as Insights or Events) to see if new data is appearing as expected.
- Use filters on properties like $warehouse_import_id or $warehouse_type in your reports to confirm whether recent data from the warehouse is being ingested (Warehouse Connectors FAQ).
- Monitor your data usage in Organization Settings > Usage, filtering by data source to see if warehouse connector imports are being counted (Monitor data usage).If you are not seeing expected syncs in the sync history and no new data in your reports, it is likely that the sync is not working correctly. In this case, you may need to review your connector configuration or contact Mixpanel support.The knowledge sources do not mention any other automated or system-level checks beyond these methods.
