DevOps / AppDynamics Interview questions
What are the types of agents available in AppDynamics?
AppDynamics ships several agent families, each targeting a different layer of the stack, and most production deployments run more than one type side by side on the same host or application.
| Agent Type | Monitors |
| App Agents (Java, .NET, Node.js, PHP, Python, C/C++ SDK) | In-process application code and business transactions |
| Machine Agent | Host CPU, memory, disk, and custom extensions |
| Network Agent | TCP connection quality and packet-level network metrics |
| Database Agent | Database server performance and query execution |
| Analytics Agent | Log and transaction data feeding Business iQ / Analytics |
| EUM Agent (Browser JS, Mobile SDK, Synthetic) | Real and simulated end-user experience |
Which combination you deploy depends on what you need visibility into — a pure front-end team might only need Browser RUM, while a platform team troubleshooting latency usually runs App, Machine, and Network Agents together.
Which agent captures simulated, scripted user journeys rather than real traffic?
Which agent feeds data into Business iQ / Analytics?
