Rate Limits

All of the API endpoints are rate limited. Once you exceed a certain number of requests in a specific period, Datadog returns an error.

If you are rate limited, you will see a 429 in the response code. Datadog recommends to either wait the time designated by the X-RateLimit-Limit before making calls again, or you should switch to making calls at a frequency slightly longer than the X-RateLimit-Limit / X-RateLimit-Period.

Rate limits can be increased from the defaults by contacting the Datadog support team.

Regarding the API rate limit policy:

  • Datadog does not rate limit on data point/metric submission (see metrics section for more info on how the metric submission rate is handled). Limits encounter is dependent on the quantity of custom metrics based on your agreement.
  • The rate limit for metric retrieval is 100 per hour per organization.
  • The rate limit for event submission is 500,000 events per hour per organization.
  • The rate limit for event aggregation is 1000 per aggregate per day per organization. An aggregate is a group of similar events.
  • The rate limit for the Query a Timeseries API call is 1600 per hour per organization. This can be extended on demand.
  • The rate limit for the Log Query API call is 300 per hour per organization. This can be extended on demand.
  • The rate limit for the Graph a Snapshot API call is 60 per hour per organization. This can be extended on demand.
  • The Log Configuration APIs can be read 84 times per minute per organization for a total of 5040 calls per hour, and can be updated 2 times per minute per organization for a total of 120 calls per hour. This can be extended on demand.
The list above is not comprehensive of all rate limits on Datadog API's. If you are experiencing rate limiting, reach out to support for more information about the API's you're using and their limits.
