Viewing Cluster Node Details and Metric Values

 

With cluster node details and host charts, you can view real-time and historical values of all metrics that Contrail Insights monitors. Charts provide you with a way to view metrics for multiple entities across layers and organized by physical host, project, or aggregate. The charts update with the latest data streamed from the Contrail Insights Platform without needing to refresh. You can select which entities to display on the charts, and select the time period that is displayed. When you hover over the charts, a pop-up box shows the actual values for the selected entities at a specific point in time. Figure 2 shows real-time metric values streamed from Contrail Insights.

Note

For Contrail Insights releases prior to 3.2.6: In order to view host charts, your Contrail Insights license subscription must be active.

Time

The Time in the Settings dialog box (see Figure 2) provides navigation to a specific point in time that you want to view. Use the time and date drop-down list to select a range. Using the range selected, you can use the time slider to fine tune the time range by scaling up or down. This time range is used to query data that will be drawn in the visualizations.

Legend

The Legend shows which entities are currently being displayed in the charts. See Figure 2. You can select a subset of entities to display to improve the clarity of the charts and focus on specific entities. The first five series are selected by default. The entity list is categorized and searchable in the Settings dialog box.

Chart Data Values

The host charts show the latest data for up to four different metrics, updating in real-time from a stream of data from the Contrail Insights Platform. When the cursor is positioned over the charts, a pop-up box shows the data values at that particular time. Charts can be zoomed in or out by opening the Settings dialog box and adjusting the time range. Four charts are displayed on the Dashboard at all times.
