Viewing the Network Monitoring Dashboard

The Network Monitoring Dashboard page displays information about nodes based on the surveillance view configured for the user (in the /opt/opennms/etc/surveillance-views.xml file).

To access the Network Monitoring Dashboard page:

  1. Select Network Monitoring > Dashboard.

    The Dashboard page, which has five sections or tables (also known as dashlets), appears:

    Note:

    If the Dashboard does not display information about all your nodes, you should resynchronize your nodes in Network Monitoring. For more information, see Resynchronizing Nodes in Network Monitoring.

    • Surveillance View—Displays surveillance categories in a table as determined by the configuration in the /opt/opennms/etc/surveillance-views.xml file

    • Alarms—Displays alarms on the nodes

    • Notifications—Displays notifications on the nodes.

    • Node Status—Displays status of the nodes.

    • Resource Graphs—Displays the first resource graph for the first node

Using the Dashboard Surveillance View

The Surveillance View:view-name dashlet determines what content is displayed on the other dashlets on the Dashboard page. By default, information about all the nodes that are part of the surveillance view (Show all nodes option) is displayed on the Dashboard page.

Note:

  • The rows and columns (surveillance categories) displayed in the Surveillance View:view-name table (dashlet) are determined by the configuration in the /opt/opennms/etc/surveillance-views.xml file.

  • The color-coding in the cells in the table is based on the severity of the event.

You can control the display of information in the other dashlets on this page by one of the following tasks:

  • Click the first column of a row or column to restrict the information displayed in the rest of the dashlets to the nodes that belong to that surveillance category. The row or column that you clicked is highlighted.

  • Click a cell in the table (other than the one in the first row or column) to restrict the information displayed in the rest of the dashlets to the nodes that belong to the surveillance categories defined by the row and column. The cell that you clicked is highlighted.

Depending on the selection in the Surveillance View:view-name dashlet, the Alarms, Notifications, Node Status, and Resource Graphs display information about the nodes that match the surveillance categories.

  • The Alarms dashlet (table) displays the outstanding alarms for the nodes selected in the Surveillance View dashlet. In the header of the table, the total number of alarms and the current count of the alarms (for example, 6 to 10 of 34) are displayed. The information displayed about each alarm is shown in Table 1. You can click << to view the preceding set of alarms or click >> to view the next set of alarms.

  • The Notifications dashlet (table) displays the notifications for the nodes selected in the Surveillance View dashlet. In the header of the table, the total number of notifications and the current count of the notifications (for example, 1 to 5 of 12) are displayed. The information displayed about each notification is shown in Table 2. You can click << to view the preceding set of notifications or click >> to view the next set of notifications.

  • The Node Status dashlet (table) displays the status of the nodes selected in the Surveillance View dashlet; a node is displayed in this table only if a service on the node is down. In the header of the table, the total number of nodes and the current count of the nodes are displayed. The information displayed about each node is shown in Table 3. You can click << to view the preceding set of nodes or click >> to view the next set of nodes.

  • The Resource Graphs dashlet (table) enables you to view the resource graphs of the nodes selected in the Surveillance View dashlet. The fields displayed in this dashlet is shown in Table 4. You can click << to view the preceding resource graph or click >> to view the next resource graphs. The default period over which the graphs are plotted is one week.
