You can see a list of all the topics in your cluster by clicking on the Topics menu item on the left panel. A new page is opened on the right, as shown below.
You can filter the topics shown and you can also sort the table by clicking on the column headers. Clicking on a topic name opens a new page for monitoring that topic instance on the right, as shown below.
On top of the page, there are two graphs that show various metrics of the topic. See the the graph section for more information.
Under these charts is the Topic Operation Statistics table. From left to right, this table lists the IP addresses and ports of each member, and counts of the messages published and received per second in real-time. You can select the period in the combo box placed at top right corner of the table to show the table data. The available values are Since Beginning, Last Minute, Last 10 Minutes and Last 1 Hour.
