An administrator is asked to improve the capacity of an Events Service cluster. What is the recommended way to add capacity to the cluster?

Question

Options

• AAdd a new Events Service cluster to share the load.
• BAdd nodes running on machines with identical hardware matching the existing nodes.
• CAdd more storage to the master nodes of the cluster.
• DAdd more storage to as many of the existing nodes as possible.

• A
  9% (2)
• B
  70% (16)
• C
  4% (1)
• D
  17% (4)

Explanation

According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the recommended way to add capacity to the Events Service cluster is to add nodes running on machines with identical hardware matching the existing nodes. This will increase the data storage, replication, and redundancy of the cluster, as well as the processing power for queries. The Events Service cluster is horizontally scalable, so nodes can be added as your data storage requirements grow. The Events Service must run on dedicated machines with identical directory structures, user account profiles, and hardware profiles. For heap space allocation, AppDynamics recommends allocating half of the available RAM to the Events Service process, with a minimum of 7 GB up to 31 GB1. Solid-state drives (SSD) can significantly outperform hard disk drives (HDD), and are therefore recommended for production deployments.
