| Application Performance Management |
 App Server Agents attach to monitored applications and send data to the  Controller via connection  .
|
| Server Visibility |
 Machine Agents reside on monitored servers and report data to the  Controller via connection  .
|
| Application Analytics |
The Analytics Dynamic Service (formerly called the Analytics plugin) on the  App Server agent communicates with a local  Analytics Agent instance. One or more Analytics Agents in a deployment send data to the  Events Service via connection  . The Analytics Agent is bundled with the Machine Agent but can be installed and run individually as well. |
| Database Visibility |
The  Database Agent connects by JDBC to monitored databases. The agent sends data to the  Controller (via connection  ), which uses the  Events Service to store certain types of data. |
| End-User Monitoring |
For an on-premises EUM installation, you configure a connection to the web and mobile real user monitoring agents to the on-premises  EUM Server via connection  . The EUM Server sends data to the  Events Service cluster via connection  . The optional  Custom EUM Geo Server stores EUM Geo Resolution data taken via connection  . The optional  Synthetic Server receives synthetic job requests from the Controller, which are then fetched from the Synthetic Services via connection  . |
