The following guidelines can help you determine additional disk and RAM required for the machine hosting the Controller that is monitoring the Database Agent. For very large installations, you should work with your Splunk AppDynamics representative for additional guidelines.

For on-premises installations, the machine running the Controller and Event Service will require the following additional considerations, for a data retention period of 10 days:

• 1–10 collectors: 2 GB RAM, Single CPU
• 10–20 collectors: 4 GB RAM, 2 CPUs
• More than 20 collectors: 8 GB RAM, 4 CPUs
