Quotas & Filtering

A subscription to Sentry primarily entails a resource quota on the amount of events you can send within a window of time. These windows apply to a 60-second bucket for old plans and a one month bucket for new plans. Your subscription will provide a rate limit which is the maximum number of events the server will accept during that period on old plans, and the same can be configured for new plans. The server will respond with a 429 HTTP status code when this threshold has been reached.

Additionally, some plans may also include a daily rate limit. For example, you’ll be restricted to a maximum of 250 events per day if you’re on the Limited plan.

Increasing Quotas

Each tiered plan in Sentry has a predefined rate limit. The more expensive the plan, the more data you’re allowed to send. While the plans available will fit most individual and small business needs, there often arises a need for more. Fear not, Sentry is designed to handle large throughput, and if your team needs more, we’re happy to help. Reach out to your account manager, or send an email to support@sentry.io to learn more about increasing capacity.

Rate Limiting Projects

If you’re on our Large or Enterprise plan we support per-key rate limits. These allow you to set the maximum volume of events a key will accept during a period of time.

For example, you may have a project in production that generates a lot of noise. With a rate limit you could set the maximum amount of data to “500 events per minute”. Additionally, you could create a second key for the same project for your staging environment which is unlimited, ensuring your QA process is still untouched.

To setup rate limits, navigate to the Project you wish to limit, go to [Project] » Client Keys. Select on an individual key or create a new one, and you’ll be able to define a rate limit as well as see a breakdown of events received by that key.

Inbound Filters

In some cases, the data you’re receiving in Sentry is hard to filter, or you simply don’t have the ability to update the SDK’s configuration to apply the filters. Due to this Sentry provides several ways to filter data server-side, which will also apply before any rate limits are checked.

Built-in Filters

Various built-in filters are available within Sentry. You can find these by going to [Project] » Project Settings » Inbound Filters. Each filter caters to specific situations, such as web crawlers or old browsers, and can be enabled as needed by the specific application.

IP Blocklist

If you have a rogue client, you may find yourself simploy wanting to block that IP from sending data. Sentry supports this by going to [Project] » Project Settings » Inbound Filters and adding the IP addresses (or subnets) under the Filter errors from these IP addresses section.

Filter by releases

In the case you have a problemeatic release that is causing an excessive amount of noise, you can ignore all events from that release. Sentry supports this by going to [Project] » Project Settings » Inbound Filters and adding the releases under the Filter errors from these releases section.

Note

Filter by releases is avaliable only on Large and Enterprise Plans

Filter by error message

You can ignore a specific or certain kind of error by going to [Project] » Project Settings » Inbound Filters and adding the error message under the Filter errors by error message section.

Note

Filter by error message is avaliable only on Large and Enterprise Plans

Filter by issue

If there is an issue that you are unable to take action on but that continues to occur, you can delete and discard it from the issue details page by clicking “delete and discard future events.” This will delete most data associated with an issue and filter out matching events before they ever reach your stream. Matching events will not count towards your quota.

Note

Discarding issues is avaliable only on Medium, Large and Enterprise Plans

Attributes Limits

Sentry imposes hard limits on various components within an event. While the limits may change over time and vary between attributes most individual attributes are capped at 512 bytes. Additionally, certain attributes also limit the maximum number of items.

For example, extra data is limited to 100 items, and each item is capped at 512 bytes. Similar restrictions apply to context locals (within a stacktrace’s frame), as well as any similar attributes.

Generic attributes like the event’s label also have limits but are more flexible depending on their case. For example, the message attribute is limited to 1024 bytes.

The following limitations will be automatically enforced:

  • Events greater than 100k are immediately dropped.
  • Stacktraces with large frame counts will be trimmed (the middle frames are dropped).
  • Collections exceeding the max items will be trimmed down to the maximum size.
  • Individual values exceeding the maximum length will be trimmed down to the maximum size.
