Real-time metrics

You can see a real-time view of the operations of your Diffusion™ Cloud service by going to the real-time metrics page.

Enabling real-time metrics

Real-time metrics are enabled by default for all Diffusion Cloud services.

Note:

When active, the real-time metrics page uses messages to provide information about your Diffusion Cloud service. These messages count as part of your data usage.

A single user viewing the real-time metrics page in its default layout for 24 hours incurs approximately $1 of message usage in that time. (This can be up to $5 if your average message size is large.)

You can disable or enable real-time metrics from the Settings page of your Diffusion Cloud Dashboard. Your Diffusion Cloud service restarts to disable or enable real-time metrics.

Viewing real-time metrics

Access the real-time metrics from the Usage page of your Diffusion Cloud Dashboard.

Log in

To access the real-time metrics, you need to supply a principal and password. The principal you use to log in must have permissions to view and act on information on Diffusion Cloud.

Ensure that the principal you use to log in to the real-time metrics has the ADMINISTRATOR role. For more information, see Role-based authorization.

Information about your Diffusion Cloud service, such as its version number, its uptime, and when it was last started.
Clients
A graph of concurrent client connections over time.
Topics
A graph of the number of topics over time.
Message rate (last minute)
A graph of the number of messages being sent per second over the previous minute.
Memory usage
A graph of the amount of heap and non-heap memory used by the JVM that runs your Diffusion Cloud service over time.
Data transfer rate (last minute)
A graph of the number of bytes of data being transferred per second over the previous minute.

Topics

The Topics table enables you to browse the live topic tree, to subscribe to topics, and to fetch the current value of the topic data. The table also shows the number of clients subscribed to the topic, the number of messages sent, and the number of bytes sent.

Use the check boxes to select a topic or topics and the Subscribe button to subscribe the real-time metrics page to that topic. If the real-time metrics page is subscribed to a topic, the current value of the topic data is displayed in the Value column of the table.

Use the Add to Overview button to add topics to the metrics panels.

Use the pulldowns next to the Subscribe and Unsubscribe buttons to recursively subscribe or unsubscribe to all the topics in a path.
