10. The medium of claim 1 , wherein the selected agents include an application performance monitor agent configured to obtain run-times of one or more routines of one of the application components, the run-times each corresponding to a during of time a routine takes to service a portion of a transaction serviced by a plurality of routines.

11. The medium of claim 1 , wherein:

a given one of the selected agents is configured to monitor a corresponding container of the multi-container application via a Java Management Extension interface without the given one of the selected agents executing in a shared user-space instance with the corresponding container.

12. The medium of claim 1 , comprising:

adjusting configurations of one or more agents based on the composition record, wherein adjusting configurations comprises:

changing a metric monitored;

changing a threshold for an alarm; and

determining an interface by which information is ingested by a selected agent.

13. The medium of claim 1 , comprising:

accessing, with a given agent, a packet sent or received by a given container of the multi-container application;

adjusting a configuration of the given agent based on the packet.

14. The medium of claim 1 , comprising:

accessing, with a given agent, a packet sent or received by a given container of the multi-container application by reading a value from a network interface buffer either on the buffer or in system memory allocated to a driver of the network interface; and

adding another agent to monitor the multi-container application based on the packet.

15. The medium of claim 1 , wherein:

selecting a plurality of infrastructure or application performance monitoring agents comprises steps for selecting agents.
