System Requirements

The EUM agent can be installed on Windows and Linux systems in both 32-bit and 64-bit versions. For information about the system requirements, please refer this topic.

Java Memory Size (JVM Heap Size)

You need to ensure sufficient java memory size is available for the EUM agent. The following values are recommended for various deployments.

Up to 50 Monitors - 256 MB of java
50 to 100 Monitors - 512 MB of java
100 and > Moniotrs - 1024 MB or above

You can change the java memory in the StartServer.bat file under /EUMAgent Home/ folder. Change the value of -Xmx256M attribute.

Increasing Data Collection Threads

For collecting data from 50 Monitors, the thread count should be 25. For 50 to 100 monitors, increase the thread count to 40 to 50.

For 100 monitors or above, increase the thread count to 50 to 75.

You can change the thread count in agent.conf file under /EUMAgent Home/conf folder. Change the property agent.threadpoolsize=25

Real Browser Monitor Tips

For RBM monitors, it is recommended to have a dedicated machine for RBM Playback. Since RBM scripts playback sequentially, scripts will be in queue if there are more scripts for that agent. To avoid this, configure the RBM monitors such that poll intervals of monitors should be greater than the playback time. This will minimize the queue.

While playing back the script, do not interrupt the IE or do not open a new IE. This will lead to disturbance in playback. For this, you need to provide a dedicated machine.
