Interface Utilization Summary report

Interface Utilization Summary report overview

The Interface Utilization Summary report provides a summary of utilization data for a selected group of interfaces.

Note: The Interface Utilization Summary report is based on different statistics from the Interface Overview report. The utilization values shown in the two report types will be different.

The default display is a set of graphs and a table showing ingress and egress speeds and minimum, maximum and average utilization percentages. Utilization results in the table are colored red when utilization reaches or exceeds user-defined thresholds.

Utilization calculation varies by interface type:

Note: Running the report for all Interface Types or using the Show Report On One Page option may impact report rendering time. Nokia recommends running the report only for the required interface type, and disabling pagination unless required.

When five or fewer SAPs are selected and the data is available in the database for either ingress or egress (but not both), the legend of other graphs display, but not the plot.

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

To view the report for granularities other than raw data, the aggregation rules must be enabled; see How do I configure analytics aggregation?. 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.

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.

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—Click on an entry in the Interface Name column for a 7750 SR, VSR, 7450 ESS, or 7950 XRS NE interface to launch an Interface Overview report.
