Node Power and Voltage Summary

Node Power and Voltage Summary report overview

The Node Power and Voltage Summary report shows detailed information about NE power and voltage. The report provides tables showing DDM, lane DDM, coherent optical port, and hardware resource statistics, and can drill down to the Optical Power and Voltage Summary report for more information.

For hardware resource statistics, only minimum and maximum voltage are displayed; there is no average counter.

Limitations

Report limitations include:

Low voltage threshold and high voltage threshold report inputs are applicable only to DDM statistics and hardware resource statistics.
Periodic counters are used for hardware resource statistics if non-periodic counters are not present in aggregation tables.

Use cases

Troubleshooting—Confirm that NE power is in the optimum operating range to determine if it is a cause of network impairment.

Prerequisites

The following table describes the aggregation rules that must be enabled and the statistics to be collected. To view the report for granularities other than raw data, the aggregation rules must be enabled; see How do I configure analytics aggregation?.

Report characteristics

The following table lists the principal report characteristics.

Table 11-8: Node Power and Voltage Summary report characteristics

Characteristic	Value
Data type	Statistics
Source database	Auxiliary database
Report inputs	Prompt	Notes
	End date	Calendar date or relative date (for example, two days ago) and time
	Report range	Length of time to be reported, in hours or days
	Granularity	Aggregation types: Raw Collection Interval Hourly Daily Weekly Monthly
	Region	Select a region.
	Subregion	Only subregions below the top-level region are displayed in the prompt. Objects in the lower subregions are automatically selected when their subregion is selected.
	NE types	Search using partial names. Select individual items or click Select All.
	NEs
	Low voltage threshold	Specify the value using expressions like > or <.
	High voltage threshold	Specify the value using expressions like > or <.
	Logo Resource ID	The logo to add to the report. Enter the Resource ID of the logo image in the Images folder. The default is the Nokia logo. To create the report without a logo, leave the Logo Resource ID field blank.
	Logo Position	Choose Left, Middle, or Right. The logo appears on the left on the first page of the report if you choose Left or Middle.
	Show threshold violations only	Select to see threshold violations only.
	Show report output on one page	Select the check box to enable pagination. Note: Using the Show report output on one page option when creating reports as drill-downs may impact report rendering time. Nokia recommends disabling the Show report output on one page option when creating reports.
Drill-down support	Yes—Drills down to Optical Power and Voltage Summary report
