Interface Utilization With Forecast (NSP) report

Interface Utilization With Forecast report overview

The Interface Utilization with Forecast (NSP) report includes utilization data for NEs managed by the NFM-P only or by the MDM (model-driven Nokia) only. The report provides forecast utilization data for a single interface. The default display is a set of graphs showing total, ingress, and egress traffic.

To generate a forecast, you must provide at least two seasons of data, although more may be required if the input data is not linear. For example, if you choose a seasonality value of 7 and the granularity is daily, you must use a report range of at least 14 days.

When the forecast algorithm fails, a pop-up message displays with the recommendation that you either lower the seasonality value or increase the report range.

You may consider scheduling the report, as it takes several minutes to generate.

Use cases

Capacity planning—Use the report to examine interface utilization patterns for planning future capacity requirements.

Limitations

Minimum and maximum throughput aggregation cannot be compared with the minimum and maximum throughput values generated from raw granularity.

Prerequisites

The session time zone must match the aggregation time zone. When these two settings are different, the report does not run correctly and the system returns an error. See section How do I configure the Analytics session time zone? for more information about configuring the session time zone.

To view the report for daily and monthly granularities, the aggregation rules must be enabled; see How do I configure analytics aggregation?. Enable aggregation and configure telemetry subscriptions; see the Telemetry information on the Network Developer Portal and the NSP Data Collection and Analysis Guide.

The following table describes the aggregation rules and the accounting policies that must be configured for the NEs on which statistics are to be collected; see the NSP NFM-P Statistics Management Guide for information about configuring an accounting policy.

Forecast Periods

The range for the forecast to work. The value is based on the granularity selected. For example, a period of 30 would mean 30 days if the granularity is daily, and 30 months if the granularity is monthly.

Periods per Season

The frequency at which there is a similarity in data. For example, the frequency at which a plot has similar values. The behavior is the same as the forecast period. For example, a period of 7 would mean 7 days if the granularity is daily, and 7 months if the granularity is monthly.

Logo Resource ID

The logo to add to the report. Enter the resource ID for the logo image uploaded to the Images folder, if any. If no logo ID is provided, the logo area will be blank.

Logo Position

Choose Left, Middle or Right. The logo will be placed on the left of the first page of the report for both the left and middle options.

Show report output on one page

Select the check box to enable pagination.

Nokia recommends using the Show report output on one page option when creating reports. A high forecast periods per season may impact the time that it takes for the report to load the forecast.

Drill-down support

No
