NAE Graph In-Depth Look

Time-Series Graph Overview

An NAE Agent displays a visualization of monitored data in a graph that plots values against time. This graph connects the values of the monitored resources sampled regularly to show changes over time. These values are mapped every 5 seconds straight from the Time-Series Database.

An agent can have more than one time-series graph, but only one graph for that agent is displayed on the Analytics dashboard.

Interacting with the Graph

Customizing data displayed on the graph

There are several ways you can interact with the time-series graph to change what is shown.

  1. You can view a tooltip to show the values at a given moment in time by hovering the cursor over a trendline. The tooltip also displays the date and time for the displayed sample.

Additionally, clicking on an entry in the legend will toggle between making that entry's name gray and causing its line to disappear from the graph, or making the monitor's name bold and causing its line to reappear on the graph.

  1. You can choose which monitored resources to display by clicking the Configure Chart button on the top right and opening the Customize Chart dialog window.

The default monitoring mode is Automatic Monitoring, in which certain meaningful monitors and resources are automatically selected to be displayed on the agent graph. To customize what resources (i.e. monitored values) are displayed on the graph, select the Customize Monitoring radio button.

The graph shows data lines for up to eight metrics at a time.

The various columns in the table can be sorted and filtered.

The graph displays alerts for all metrics being monitored; however, the graph shows data lines for up to a maximum of eight metrics at a time. You can choose which metrics are shown on the graph: to display a metric in the graph, check its corresponding Show column box, and to remove a metric from the graph, uncheck its corresponding Show column box.

If a monitor is a wildcard type that monitors multiple metrics, clicking on its Show column box will open a dialog window in which you can choose which resources will be displayed on the graph.

The Resources Selected column shows how many resources are selected out of the total
resources being watched by that monitor.

If a monitor uses an aggregation function to condition raw data before displaying it, that function is displayed in the Aggregation column.

Zooming in on the graph

There are several different ways to focus in on a specific time period on the time-series graph.

  1. You can zoom in and out on the graph by selecting a zoom level from the options displayed at the top left of the graph: 1 hour, 1 day, 10 days, 30 days, 90 days, 180 days, and 1 year. You can also select Custom to specify a date and time range.

  1. You can also choose a custom date and time range by highlighting a section of the graph as follows:
    a. Hover the cursor over the graph so that a vertical line appears.
    b. Click and drag the vertical line to the left or right to define the time period you want to view.
    c. Release the mouse button to redraw the graph for the selected period.

In the custom view, the date and time range for the displayed graph is shown on the top left under the zoom level selection buttons.
To reset the graph, select the default Live zoom level.

Downloading the graph as an image or spreadsheet

You can download the graph either as an image or as a set of comma-separated values that can be opened in spreadsheet editors. The download options are accessed by clicking the down arrow in the top right of the time-series graph.

Jumping to an alert on the graph

The graph may not show all triggered alerts, depending on what time period is currently being displayed. To change the graph to display an alert and its associated metric, ensure that you are on the Agent Details page, and then select the desired alert in the Alerts table and click Navigate.

It's possible that the metrics triggering the alert are being monitored but not currently being shown in the graph. The metrics that are being shown on the graph are listed in the legend at the bottom of the graph.

To adjust the graph display to show the metrics responsible for causing the alert, locate the alert on the graph and click its associated triangle symbol at the top of the graph. The Alert Details dialog box is displayed.

Alerts are represented by triangles at the top of the graph.
