Server.log contains the following error message, while EUM metrics continue to be collected successfully:
com.singularity.ee.controller.beans.eumcloud.MetricsCountLimit|_ThreadID=2909754;_ThreadName=Thread-5;|Metric name "EUM|Browser|Chrome|Chrome 56|First Byte Time 80th percentile (ms)" matches but the limit of 100000 OTHER_WEB metrics has been reached for app 57 [count=118121]|#]
This issue occurs when the property appdynamics.controller.eum.otherWeb.metricsCount.limit
maximum has been reached.
Note: The com.singularity.ee.controller.beans.eumcloud.MetricsCountLimit
is a shared limit for the total of distinct EUM metric names.
Change the "metric count limit" property to a higher value.
1. Login to the Controller: http://<controllerurl>/controller/admin.jsp;
2. Navigate to Controller Flags Servlet: http://<controllerurl>/controller/private/ControllerFlagsServlet
3. Edit the property appdynamics.controller.eum.otherWeb.metricsCount.limit
value and click submit to save.
The Controller will pick up the change.
Note: Before increasing the metrics count limit, try to manage all pages, AJAX, iFrames, and mobile request names using Custom Naming/Exclude rules. Be aware that deleting any pages, mobile requests, etc, will also delete the associated metrics (and metric names).
