Data and quotas are interconnected in Sentry. At the most basic level, when you subscribe to Sentry, you pay for the amount of data — events (errors and transactions) and attachments — to be tracked. Each of these data categories has a
To see which of your projects are using up your quota, you can review the "Usage" tab of Stats. This page is accessible to all members of your organization, so a Billing or Owner member can share this page with the developers directly responsible for a given project. In addition, you can come back to this page to check if the changes you've made are having the desired effect:
You can also download a project breakdown report in the "Usage History" tab of Settings > Subscriptions (only accessible to Owner and Billing members of your Sentry organization).
Sentry's flexibility means you can exercise fine-grained control over which events and attachments count toward your quota. This page provides you with high-level information about strategies for managing your quota, but you can get more detailed information in:

Let's clarify a few terms to start:
- Event - An event is one instance of you sending data to Sentry, excluding attachments. Generally, this data is an error or a transaction.
- Error - What counts as an error varies by platform, but in general, if there's something that looks like an exception, it can be captured as an error in Sentry. Sentry automatically captures errors, uncaught exceptions, and unhandled rejections, as well as other types of errors, depending on platform. A grouping of similar errors makes an issue.
- Transaction - A transaction represents a single instance of a service being called to support an operation you want to measure or track, like a page load. Transaction events are grouped by the transaction name.
- Attachment - Attachments are stored additional files, such as config files, log files, or stored mini-dumps, that are related to an error event. Unless the option to store crash reports is enabled, Sentry will use these files only to create an event, and then drop them.
- Data - Anything you send to Sentry. This includes events (errors or transactions), attachments, and event metadata.
- Quota - Your quotaThe monthly number of events that you pay Sentry to track.is the amount of data (errors, transactions, attachments) that you pay Sentry to track.
Sentry completes a thorough evaluation of each event to determine if it counts toward your
Before completing any of these evaluations, Sentry confirms that each event includes a valid DSN and project as well as whether the event can be parsed. In addition, for error events, Sentry validates that the event contains valid
This list is ordered from easiest or least time-consuming to most challenging or potentially time-consuming. This isn't the order in which evaluations take place.
Sentry’s spike protection prevents huge overages in error events from consuming your event volume, and it's enabled for all accounts by default. You can confirm that spike protection is enabled in Settings > Subscription. Learn more about how spike protection works and how to manage spikes in Manage Your Error Quota.
Events and attachments that exceed your
You can add limits for error events on a per-project basis in [Project] > Settings > Client Keys (DSN). If the event rate limit for a project has been exceeded, and your subscription allows, the event won't be counted. You can also rate limit attachments on an organization level in Settings > Security & Privacy. Learn more in Manage Your Error Quota and Manage Your Attachments Quota.
In some cases, repeated events can count against your
If an inbound filter is applied for a type of error, transaction, or attachment, and your subscription allows, it won't be counted. You can manage these in [Project] > Settings > Inbound Filters. Learn more in Manage Your Error Quota, Manage Your Transaction Quota, and Manage Your Attachments Quota.
If a sample rate is defined for the SDK, the SDK evaluates whether this event should be sent as a representative fraction of events, effectively limiting the number of errors and transactions you send to Sentry. Setting a sample rate is documented for each SDK, but you can also learn more in Manage Your Error Quota and Manage Your Transaction Quota.
All Sentry SDKs support the
beforeSend callback method, which you can use to modify the data of an error event or to drop it completely. Many also support
beforeSendTransaction. Learn more in Manage Your Error Quota and Manage Your Transaction Quota.
The SDK configuration either allows an event to be sent to Sentry or filters it out. Configuration is documented for each SDK, but you can also learn more in Manage Your Error Quota and Manage Your Transaction Quota.
Sentry imposes limits on various fields within an event, as well as the size of full events and the requests they are sent in, which can affect your attachments
