Area charts in SolarWinds NTA

Area charts are the default charts for all detail views. They display resources within a defined traffic level and time frame. They provide a more comprehensive view of traffic and bandwidth usage data than pie charts, so area charts always include a one-to-one relationship of table-to-chart information.

Like pie charts, if more items exist than what is configured to display, SolarWinds NTA creates a category in the legend of the area chart called Remaining traffic. If fewer items exist than what the chart is configured to display, the chart shows only those resources that exist.

Display data for a specific time point

To display exact transmission details for a specific point in the time, point your mouse to a specific point on an area chart. The detailed information displays within the chart and in a tool tip.

The Top 5 Endpoints data shown in the area chart tell us that conversations involving the LAB-VCENTER50 (10.199.1.90) endpoint generated substantially more traffic than the other top 4 endpoints.

The above graph displays a data point at 53 Mbps which is the rate the total data was sent at. This should not get confused with the amount of data transferred over the period of time set for the total traffic graph. Mbytes and a per second data point (Mbps) are two different measurements. The data in the peak of the graph is not meant to match the data in the legend of the resource.

Zoom in to see a specified time period

For a more detailed look at resource use, locate the slider tool beneath the area chart. Move it right or left to display an in-depth view of a selected portion of the area chart. This feature allows you to visually pinpoint and compare endpoint traffic flow data using an exact time.

Hide or show certain items

To display only certain endpoints out of those already selected for review, for example, the bottom two out of the top five, clear the boxes for top three endpoints.

The top three endpoints still display in the legend, but do not display in the table, making for easy comparisons between the bottom two endpoints. You can also use the slider below the graph for a more detailed view of the endpoints, in the same way as described above.
