AppDynamics performance profiles are predefined sets of system requirements and configuration settings that are designed to support different levels of load and scalability for the AppDynamics platform. The performance profiles range from small to extra large, depending on the number of agents, metrics, and events that the platform needs to handle. The large and extra large performance profiles differ from other profile types in the following ways:
They require an enterprise-grade database: The large and extra large performance profiles require an external MySQL database that is enterprise-grade, meaning that it has high availability, scalability, performance, and security features. The database should also have enough disk space, memory, and CPU resources to handle the expected load and growth. The AppDynamics platform uses the database to store configuration data, metric data, event data, and analytics data12.
An alert is generated when disk space falls below 2 GB: The large and extra large performance profiles have a built-in alert mechanism that notifies the administrator when the disk space on the Controller host falls below 2 GB. This isbecause the Controller needs enough disk space to store temporary files, logs, backups, and snapshots. If the disk space is insufficient, the Controller may experience performance degradation, data loss, or corruption. The administrator should monitor the disk space usage and free up space or add more disk capacity as needed34.
The other statements are false because:
A. They do not need to be installed on a bare metal server. The large and extra large performance profiles can be installed on any supported operating system, such as Linux or Windows, and on any supported platform, such as physical, virtual, or cloud. However, the host machine should have enough CPU, memory, and network resources to meet the performance profile requirements12.
B. They do not need to be run with the High Availability Toolkit. The High Availability Toolkit is an optional tool that can be used to configure and manage a high availability deployment of the AppDynamics platform, where multiple Controllers are clustered together to provide redundancy and failover. The High Availability Toolkit can be used with any performance profile, not just the large and extra large ones. However, the High Availability Toolkit requires a license and additional hardware and software resources .
C. They are supported on Windows. The large and extra large performance profiles can be installed on Windows Server 2012, 2012 R2, 2016, or 2019, as long as the host machine meets the performance profile requirements. However, some features or configurations may not be available or supported on Windows, such as the High Availability Toolkit, the Enterprise Console, or the Events Service12.
