How do I plot a telemetry chart?

Service Disruption

The name of an object, including subscriptions, baselines, indicators, templates, and chart profiles, cannot contain a semicolon (;) or backslash (\).

The use of these characters in an object identifier will result in corrupted data that must be deleted by Nokia support.

Before you begin

When you create a telemetry chart, you configure a telemetry filter. For historical data to be displayed, the data must be available in the database; see How do I manage subscriptions?.

Charts are created by streaming to the plotter. Historical data is queried and streamed to the plotter, then real-time telemetry subscriptions are created and the data from these subscriptions is streamed to the plotter.

Data Collection and Analysis Visualizations times out if telemetry data is not received. The time-out limit is either double the collection interval or two min, whichever is greater.

Chart limit

Up to 64 objects can be charted at a time. The number of objects is the number of resources returned by the object filter, multiplied by the number of counters.

If your object filter returns one resource, for example, one NE, you can chart up to 64 counters for the resource. If there are four resources, you can chart up to 16 counters per resource.

Note: Chart rendering performance will be impacted by many factors when attempting to chart a large number of items. For example, short collection intervals, long historical time ranges resulting in a total of tens of thousands of data points, browser performance, and network speed all affect chart rendering time.

Steps
Create a chart
 
1 

Open the New Chart window:

  • From Data Collection and Analysis Visualizations, Telemetry Charts, click png3.png Chart.

  • From Data Collection and Analysis Management, Subscriptions, choose a subscription and click png2.png (Table row actions), Open in Data Collection and Analysis Visualizations.

2 

In the window that opens, configure the parameters in the top panel:

  1. Configure the Collection Interval parameter. If you are using NFM-P telemetry data, verify that the collection interval is long enough to allow time for Visualizations to receive the data before timing out.

  2. From the Time Range drop-down list, choose the amount of historical data to display.

  3. Click Combine charts to plot data from multiple data series on the same chart.

3 

Click png3.png Definition.

The telemetry and resource filter definition panels are displayed.

4 

Enter information in the Telemetry Type field. As you type, the field filters for available telemetry types to match your input.

Choose the telemetry type from the list of matches.

5 

Choose counters to display from the Counters drop-down list.

6 

In the Object Filter field, enter filtering information to filter the collected data.

7 

If you need to save the configuration as a chart:

  1. Click Save As.

  2. In the window that opens, enter a name for the chart and add a description if needed.

  3. Click Save.

The chart is added to the list.

8 

Click Plot.

Steps
Plot an existing chart
 
1 

To plot an existing chart with no changes:

  1. Open Data Collection and Analysis Visualizations, Telemetry Charts.

  2. Choose a chart and click png2.png (Table row actions), Chart.

2 

To edit a chart and plot it, choose the chart and click png2.png (Table row actions), Edit.

3 

Edit the parameters as needed and click Plot.

End of steps

Result

Visualizations displays a chart view showing the streaming data. While data is streaming, you can configure the Group by parameter in the upper left of the chart view to change how the data is grouped or click Configure in the upper right to view or change the configuration of the chart.

Click png5.png (Chart Details) to open the Chart Details panel on the right side of the chart view to show details about the resources.
