Panel Control Bar
The panels on a dashboard have similar control buttons as in the Explore tab with one important exception. You can use the Edit Panel function to completely re-configure a panel’s chart type, metrics displayed, aggregation type, and segmentation. If the chart type is a map, you can additionally specify link metrics.
The possible icons available in the panel control bar:
Please see the Explore Tab “Panel Button Control” section for details on the all controls except the Edit Panel button explained below.
Clicking on the edit panel gear icon changes the panel mode from viewing to editing and a new line in the panel will display the various options available for customization.
Note that customizing panels is a dynamic process. While you edit a panel on a dashboard you will see any changes take effect immediately, data even continues to be rendered in realtime so you always know what to expect when you finish.
Finish editing and save changes by clicking the checkmark icon.
Change Chart Type
Select one of the three chart types available:
Time Series Strip Chart
The time series strip charts can show multiple metrics (up to 5) over long durations of time. Zoom time by clicking and dragging over any portion of the chart or use the + / - zoom buttons. You can also click on any legend item to toggle its display on or off.
Top 10 Bar Chart
Bar charts display up to the top ten items for the metric under review. Five metrics can be added to the chart each with its own aggregation type (max/ave/min/sum). As with strip charts, you can click on any legend item to toggle that metric’s appearance on the chart.
The Map view intuitively shows interconnections between your hosts and applications as well as intra connections within a host or group. Roll your mouse wheel over the view to enlarge it.
While this view displays a single metric for each host, group or container, you will see an additional component - Link Metric – available for selection. Use Link Metric to see network communication details between items. The zoom buttons on this chart will change the size of the displayed items.
Data tables appear only when top level hosts and services views are pinned to your dashboard. You can choose to reconfigure them from the table format to other chart types but only the first metric column listed be used. Selecting to go from other charts to a data table is not an available option.
Add / Change Metrics
To change the information displayed in a panel, use the metrics pull-down menu and scroll through the list to find the desired metric. You can add 4 additional metrics to your panel for a total of 5 by clicking the ‘+’ at the end of the metrics line. Metrics can be added to strip charts, topology maps, and bar charts and any new selections will immediately be rendered in the panel.
You may also want to consider changing the panel title to reflect new functionality by clicking the pencil icon.
The aggregation type can be changed for any displayed metric by clicking the pulldown menu to the right of the metric title.
Detailed explanation of aggregation settings can be found on this support page:
You can break out the displayed data into different groupings via the ‘Segment by’ pulldown menu. The below graphic shows the change of an example host’s CPU% usage strip chart - displaying aggregate information - to one that shows CPU% usage for each container ID:
Change Link Metrics (Map Only)
Topology maps allow one additional metric to be assigned to the links between the items displayed in the view.
Time Control for Dashboards
Time Travel works on any dashboard in exactly the same way as it does on the Explore tab. Use the time navigation bar to jump back in time (Time Travel function), switch from real time mode in 10 second increments to averaged windows of time (5Min, 2Hr, 1D etc.), and pause or step forwards or backwards to any point in history to see precisely how your infrastructure was performing.
For more detail, please see the Time Control section on the Explore Tab user guide page.
