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 capture 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?
Can my environment limit be changed?
The environment limit can be adjusted. For details, please contact the Dynatrace ONE team or your sales representative.
The maximum user action count per minute limit is specific to your environment. You can configure this limit at Environments > Cluster Management Console.
