--- title: "Event Properties" description: "Learn more about searchable event properties." url: https://docs.sentry.io/concepts/search/searchable-properties/events/ --- # Event Properties Events are the underlying event data captured using Sentry SDKs — that is, errors and transactions. You can search by event properties in the following [sentry.io](https://sentry.io) pages: * Discover - in the query builder (depending on the dataset selection) * Dashboards - within the widget builder (depending on dataset selection) * Performance - only in transaction summaries * Issues - as indicated in the list below * Alerts - when creating a metric alert Please note that in Alerts only a limited number of properties are available for [filtering transaction events](https://docs.sentry.io/product/alerts/create-alerts/metric-alert-config.md#tags--properties).

[User Misery](https://docs.sentry.io/product/insights/overview/metrics.md#user-misery) is a user-weighted performance metric that counts the number of unique users who were frustrated; "frustration" is measured as a response time four times the satisfactory response time threshold (in milliseconds). It highlights transactions that have the highest impact on users. * **Type:** number ### [`user.display`](https://docs.sentry.io/concepts/search/searchable-properties/events.md#userdisplay) In order, the first available user field available: email, then username, ID, and then IP address. * **Type:** string ### [`user.email`](https://docs.sentry.io/concepts/search/searchable-properties/events.md#useremail) An alternative, or addition, to the username. Sentry is aware of email addresses and can therefore display things such as Gravatars and unlock messaging capabilities. * **Type:** string ### [`user.id`](https://docs.sentry.io/concepts/search/searchable-properties/events.md#userid) Application-specific internal identifier for the user. * **Type:** string ### [`user.ip`](https://docs.sentry.io/concepts/search/searchable-properties/events.md#userip) User's IP address. Sentry uses the IP address as a unique identifier for unauthenticated users. * **Type:** string ### [`user.username`](https://docs.sentry.io/concepts/search/searchable-properties/events.md#userusername) Username, which is typically a better label than the `user.id`. * **Type:** string
