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:

MPLS/Network & Access Interfaces use port speed
GNE interfaces use genericne.Ifspeed

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.

Report characteristics

The following table lists the principal report characteristics.

Table 14-32: Interface Utilization Summary report characteristics

Characteristic	Value
Data type	Statistics
Source database	Auxiliary database
Interface types supported	MPLS, GNE interfaces
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 minutes (minutes, min), hours (hours, h), days (days, d), or months (months, m)
	Granularity	Aggregation types: None (raw data) Hourly Daily Monthly
	NE Types	Search using partial names or wildcard (%). Select individual items or click Select All.
	Name or name pattern for NEs
	NEs
	Port modes	Select Access, Network, or Hybrid Port and port mode inputs are not required for GNE interfaces. Selecting a GNE in the NE list will automatically display GNE interfaces.
	Name or name pattern for ports	Search using partial names or wildcard (%). Select individual items or click Select All. Interfaces whose associated port speed is 0 will not be displayed in the Interfaces input prompt.
	Physical ports or LAGs
	Interface Type
	Name or name pattern for interfaces
	Interfaces
	Total threshold	Specify in bps/Kbps/Mbps/Gbps
	Ingress threshold
	Egress threshold
	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.
