Question 18

What administrative interfaces are available?

Accepted Answer

Administrative interfaces include a command-line interface (CLI) and potentially a graphical user interface (GUI). The CLI allows administrators to manage queues, channels, and users. The GUI, if available, provides a visual interface for administration.

Question 19

How is user management handled?

Accepted Answer

User management is handled through the administrative interfaces. Administrators can create, modify, and delete user accounts. User accounts are used for authentication and access control.

Question 20

What are the main configuration parameters?

Accepted Answer

Main configuration parameters include queue definitions, channel settings, and security configurations. These parameters are typically stored in configuration files and can be modified through administrative interfaces.

Question 21

What monitoring/logging capabilities exist?

Accepted Answer

PIPES provides monitoring capabilities to track system performance and message traffic. Logging is used to record system events and errors. These capabilities help administrators maintain the system.
