--- title: Event errors slug: nbde0312 canonical_url: https://docs.coveo.com/en/nbde0312/ collection: coveo-analytics source_format: adoc --- # Event errors The **Event errors** tab on the [**Data Health**](https://platform.cloud.coveo.com/admin/#/orgid/usage/health/) ([platform-ca](https://platform-ca.cloud.coveo.com/admin/#/orgid/usage/health/) | [platform-eu](https://platform-eu.cloud.coveo.com/admin/#/orgid/usage/health/) | [platform-au](https://platform-au.cloud.coveo.com/admin/#/orgid/usage/health/)) page provides a focused view of the syntactic [event](https://docs.coveo.com/en/260/) errors. By default, these errors are grouped by event type, [tracking ID](https://docs.coveo.com/en/o8rb0139/), and [search hub](https://docs.coveo.com/en/1342/), and sorted by the number of failed validations in descending order. While it's similar to the [**Event browser**](https://platform.cloud.coveo.com/admin/#/orgid/usage/health/latest-events) ([platform-ca](https://platform-ca.cloud.coveo.com/admin/#/orgid/usage/health/latest-events) | [platform-eu](https://platform-eu.cloud.coveo.com/admin/#/orgid/usage/health/latest-events) | [platform-au](https://platform-au.cloud.coveo.com/admin/#/orgid/usage/health/latest-events)), which displays all event types regardless of their status, the **Event errors** tab displays only failed syntactic validations. ## Event errors features When reviewing the **Event errors** tab, consider the following: * Each row is grouped by event type, tracking ID, and search hub. * Though event errors share the same event type, tracking ID, and search hub, they can appear on multiple rows if they failed a different number of validations for different error types. This means that the number under the **Total events** column remains the same across rows when the grouping is the same. ![Event errors tab | Coveo](https://docs.coveo.com/en/assets/images/coveo-analytics/data-health-event-errors-tab.png) 1 Get started by adjusting the date period according to the timeframe you would like to review. 2 Filter event errors by selecting the checkboxes under **Event type** and **Search hub**. 3 Select a tracking ID to filter the event errors by ID. 4 View the total number of failed validations that occurred for a given event type, tracking ID, and search hub. 5 View the total number of events for the event type, tracking ID, and search hub grouping. You may see multiple rows with the same total if events in that grouping failed a different number of times for different reasons. Each row may contain multiple types of errors, which are listed when you expand the row. 6 View the number of errors that occurred for a given error type in combination with a tracking ID and search hub. 7 Click once on the event type you want to explore. The line expands and displays additional information such as the number of errors that occurred and the number of times that each error occurred. 8 Assess the error codes and reasons for these errors. 9 Click **Show sample event** to view the payload of an event that failed validation. 10 Click icon:filter-add-2[alt=filter-add-2,width=16] next to a tracking ID if you want to view all errors for that specific ID. ## Leading practices The **Event errors** tab is a great place to start troubleshooting validation errors. It can also be used in conjunction with the other available tabs on the **Data Health** page. * Use the **Show sample event** to view the payload. Access to the payload speeds up the troubleshooting process, as it offers direct insight into the nature of the error. ** Copy and paste the payload to the analysis or debugging tool of your choice. ** You can also search through the payload to find a specific event. ![Sample event | Coveo Platform](https://docs.coveo.com/en/assets/images/coveo-analytics/data-health-sample-event.png) * Use the **Event errors** tab in conjunction with the **Event browser** tab. For example, you notice there's an error in a search event type within the `ExternalSearch` search hub. ![event errors filter | Coveo Platform](https://docs.coveo.com/en/assets/images/coveo-analytics/data-health-event-errors-filter.png) To gain more insight, you then go to the **Event browser** tab and filter by the same criteria, where the event type is `search`, the search hub is `ExternalSearch`, and the status is **Invalid**. By doing this, you can see the [client ID](https://docs.coveo.com/en/lbjf0131/) and the [visit ID](https://docs.coveo.com/en/272/) associated with the error. This helps in assessing data on specific users and their interactions within your search page and obtaining a more detailed analysis. ![event browser filter | Coveo Platform](https://docs.coveo.com/en/assets/images/coveo-analytics/data-health-event-browser-filter.png)
