What does a 'Max. user actions per minute exceeded' event mean?

A 'Max. user actions per minute exceeded' event informs you that the number of user actions generated from Real User Monitoring (Web, Mobile and OpenKit) has exceeded a limit that is specific to your environment. Once this limit is reached, Dynatrace automatically throttles the number of user sessions being captured until the number of user actions is below the limit again. The throttling is done on a user session basis in order to provide statistically correct values in Dynatrace. If the overall traffic volume drops, Dynatrace will automatically return to the capturing rate you've set for your environment.

Why does Dynatrace change the capturing rate?

The maximum user action count per minute limit is specific to your environment and is there to prevent unexpected high consumption of your license volume by unexpected IT events like unannounced marketing campaigns, unplanned load tests, DDoS attacks, aggressive web scanners, or other.

What is the impact on the data visible in the Dynatrace UI?

During the period of the event, Dynatrace reduces the amount of captured user sessions. Some of the sessions aren't captured and therefore no further analysis is applied. This means all count metrics are impacted (for example, user session count, user action count, and conversion count). Rate metrics aren't impacted since sessions are either captured fully or not at all. This includes, for example, JavaScript error rate, conversion rate, crash rate, and bounce rate.

Can my environment limit be changed?

The limit can be adjusted. For details, please contact your Dynatrace One team or your sales representative.
