Review Your Controller Capacity
If you use an on-premises Controller and plan to monitor mobile applications, assess your Controller's capacity to accommodate the increase in the number of metrics that Mobile RUM will generate. The number of individual metric data points generated depends on the level of activity of your mobile applications. As a rough guide, the use of Mobile RUM can increase the number of metric data points by as much as 15 to 25K per instrumented application, if your applications are heavily accessed by mobile users. The actual number depends on how many network requests your applications receive.
Note: The number of separate RUM metric names saved in the Controller database can be larger than the kinds of individual data points saved. For example, a metric name for a metric for iOS 5 might still be in the database even if all your users have migrated away from iOS 5. So, the metric name would no longer have an impact on resource utilization, but it would count against the default limit in the Controller for metric names per application. The default limit for names is 200,000 for Browser RUM and 100,000 for Mobile RUM.
