Which option should a Performance Analyst use in an environment where virtual machines are routinely created and destroyed?
A . Dappdynamics.agent.auto.node.prefix and -Dappdynamics.cron.vm
B . Dappdynamics.agent.reuse.nodeName and – Dappdynamics.agent.reuse.nodeName.prefix
C . Dappdynamics.http.proxyHost and -Dappdynamcs.http. proxy User
D . Dappdynamics.agent.node.metainfo and -Dappdynamics.agent.nodeName

Answer: B

Explanation:

In environments where virtual machines are frequently created and destroyed, using the agent configuration properties -Dappdynamics.agent.reuse.nodeName and – Dappdynamics.agent.reuse.nodeName.prefix can be beneficial. These settings allow AppDynamics agents to reuse node names for newly created instances, facilitating consistent monitoring and tracking across dynamic environments. This approach helps maintain clarity in application topology and ensures that performance data remains coherent even as the underlying infrastructure changes.

Reference: AppDynamics documentation on Agent Configuration: Discusses advanced agent configuration options, including node name reuse, to accommodate dynamic environments such as those with frequently changing virtual machines.

AppDynamics documentation on Infrastructure Monitoring: Offers insights into best practices for monitoring in dynamic and virtualized environments.
