2.2.2. Step 2: Distributed System at a Glance

In this step, you’ll use Admin Console to get insights about your distributed system in one central view by reviewing the content of various panels.

Note

For full details about all Admin Console views and panels, see the Views topic in the Reference chapter.

2.2.2.1. Physical and DDS Logical Trees

The system tree panels on the left, DDS Logical View and Physical View, display a hierarchical view of your distributed system. If there are warnings or errors associated with an Entity, you will see the warning WARNING_ICON or error ERROR_ICON icon attached to the Entity’s icon.

2.2.2.1.1. DDS Logical View

Logical tree

This view displays the System, Domains, and Topics in your distributed system. Expand the root System node to see the list of discovered domains; expand each domain to see its active Topics. Use the filter at the top of the panel to view only specified Entities.

Click any node to open a graphical representation of that Entity in a new tab in the main view. Hover over or click any Entity in the graphic to view detailed information about the selected Entity.

For more information, see DDS Logical View in the Views section.

2.2.2.1.2. Physical View

Physical tree

This view displays the System, Hosts, Processes, and DomainParticipants in your system. Expand the root System node and the node with the name of your host to see the list of running processes. Use the filter at the top of the panel to view only specified items.

Click on a node to open a new tab with details about the selected host, service, process, or DomainParticipant in the main view. The first time you click a DomainParticipant in the Physical View, information for its parent process displays in the main view. If selected a second time, the DDS QoS and other panels display additional data from that DomainParticipant on the right.

For more information, see Physical View in the Views section.

2.2.2.2. System Overview

System View tab

In the DDS Logical or Physical View, click the root System node to open the System tab in the main view. At the top of the System tab, note the list of domains you are currently connected to. Click Connected to domains to access the Preferences dialog, where you can decide how you want Admin Console to manage domains (automatically or manually).

The System tab includes several summary views:

  • The System graphical view tab displays a representation of all the Entities that were discovered by Admin Console. The different Entities are represented with nodes (hosts, processes, domains, etc.).

    An Entity Info panel on the right displays a summary of the whole system if nothing is selected in the graphical view, or specific information about a selected Entity.

  • The Hosts, Data Types, System Log, and System Security Log tabs display real-time details about these system elements.

For more information, see System View in the Views section.

2.2.2.3. Processes Table

The Processes table provides a summary view of all the running processes and RTI services. If it does not display at the bottom of the Admin Console window by default, go to View > Show Processes View.

In the Processes table, locate the Distributed Logger Example that was started in Step 1: System Setup, then select it in the Process column.

Processes view table

In the main view, select the Log tab to see the log messages generated by this process.

For more information, see Processes View in the Views section.
