# Events

## Docs

- [Events overview](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/events-overview.md): An overview of event data management, including ingestion, mediation, and analysis through the events dashboard.
- [Create an event definition](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/create-event-definition.md): Create and configure event definitions by importing files or manually specifying fields to structure event data.
- [Events Dashboard](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/events-dashboard.md): The Events Dashboard in Zuora Mediation provides a consolidated, filterable view to monitor event volumes, track key metrics, ingestion successes versus errors, and to investigate issues across your meters.
- [Ingestion source analysis](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/events-ingested.md): There are different ingestion options available in Zuora Mediation. Each method is suitable for different use cases, based on latency, volume, infrastructure complexity, and operational needs.
- [Event Store](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/event-store-mediation.md): The Event Store is a versatile data storage solution in the mediation system, enabling data ingestion, storage, and processing for various scenarios such as multi-region data collection, time-shifted processing, and data validation.
- [Configure an Event Store as a source](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/event-store-mediation/to-create-a-meter-with-event-store-as-the-source-follow-the-instructions-below.md): Learn how to configure an event store as a source for a custom meter.
- [Configure an Event Store as a target](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/event-store-mediation/meter-with-event-store-as-a-target.md): Learn how to configure an Event Store as a target for a custom meter by selecting and mapping event fields.
- [Re-run a meter with an Event Store source](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/event-store-mediation/meter-with-event-store-replay.md): Learn how to re-run a custom meter using an event store as a source to process specific events within a date range.
- [Configure a meter with Event Store backfill](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/event-store-mediation/meter-with-event-store-backfill.md): Learn how to backfill event data in a custom meter using an event store to re-populate or recompute meter values.
- [Event store data APIs](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/event-store-mediation/query-metering-events-with-event-store-data-apis.md): The event store data APIs let you run SQL-style asynchronous queries against raw metering events stored for a specific meter. Use these APIs to validate event ingestion, troubleshoot metering workflows, perform post‑run reconciliation, and run ad‑hoc queries for QA or analytics.
- [Meter Audit counts and Event Store counts](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/event-store-mediation/meter-audit-counts-and-event-store-counts.md): When a meter reads data from a source such as Amazon S3 and writes it to an Event Store, the counts shown in Meter Audit might not always match the number of records stored in the Event Store.
- [Event Store timezone impact](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/event-store-mediation/event-store-timezone-impact.md): The Event Store uses your tenant timezone to organize, query, and report usage events. Changing the tenant timezone after data has already been ingested can affect how historical and future data is grouped and displayed.
- [Notifications in Mediation](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/notifications-in-mediation.md): Learn how to use notifications in Zuora Mediation to receive alerts about meter runs and Event Store operations, leveraging the Events and Notifications framework.
- [Meter Session Status Change](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/notifications-in-mediation/meter-session-status-change.md): The Meter Session Status Change event triggers when a Mediation meter session changes status.
- [Meter Session Periodic Status Update](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/notifications-in-mediation/meter-session-periodic-status-update.md): The Meter Session Periodic Status Update event generates periodic summaries for a running meter session at the operator level.
- [Event Store Query Status Changed](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/notifications-in-mediation/event-store-query-status-changed.md): The Event Store Query Status Changed event fires when an asynchronous Event Store query changes status.
- [Configure Mediation Notifications](https://zuora.ferndocs.com/docs/platform/extensibility/mediation/events/notifications-in-mediation/configure-mediation-notifications.md): Learn how to configure mediation notifications by defining triggers, selecting events, setting filters, and choosing delivery options.
