Ports and Interfaces Availability Details report

Ports and Interfaces Availability Details report overview

The Ports and Interfaces Availability Details report shows the availability details for ports, LAGs, bundles, and their associated network/access interfaces for all possible modes (network, access, and hybrid).

Use cases

Service level agreement—Use the report to validate that port and interface availability meets agreed targets.

Troubleshooting—Use the report to determine if a port or interface is currently, or has previously, been unavailable.

Prerequisites

To create the report, the availability of interfaces and ports (LAG, bundle, SCADA, and POS) must be determined. An availability framework computes periodic outage time and outage counts from state change records contained in the auxiliary database data dictionary. These periodic values are aggregated to determine the availability of interfaces and ports over a period of time. A periodic table tracks the activity state and availability of interfaces and ports. The availability framework supports the creation of an availability table that aggregates the data in the periodic table based on the periodic synchronization time configured on the system. The object synchronization interval for tables registered for periodic calculation can be configured to run every 15 min (separate from the regular object synchronization task) by configuring analyticsMODictPeriodicSyncTime in the nms-server.xml file. See How do I synchronize the Analytics data dictionary table data with the NFM-P? for information about synchronizing the Analytics data dictionary table with the NFM-P.

Populate the maintenance window table in the auxiliary database with details of NE and Service maintenance; see Analytics maintenance window table. The report will run if the table is not created or empty; however, maintenance windows are treated as down time when availability is calculated.

Report characteristics

The following table lists the principal report characteristics.

Table 11-13: Ports and Interfaces Availability Details report characteristics

Characteristic	Value
Data type	Availability tables computed by availability framework
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: None (raw data) Hourly Daily Weekly Monthly
	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.
	KPI	Max Availability Min Availability Avg Availability (for all granularities except for raw granularity) Availability (for raw granularity)
	Interface	Search using partial names or wildcard (%). Select individual items or click Select All.
	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 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	No
