Ports and Interfaces Availability Summary report

Ports and Interfaces Availability Summary report overview

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

Note: Report launching time will be non-linear with respect to huge data.

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.

Limitations

Minimum and maximum throughput aggregation cannot be compared with the minimum and maximum throughput values generated from raw granularity.
Periodic Time should be non-zero for the reports to launch.

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.

Update the interval of Analytics Data Dictionary tables: The object synchronization interval for tables registered for periodic calculation must be configured to run every 15 min by configuring analyticsMODictPeriodicSyncTime in the nms-server.xml file; see How do I synchronize the Analytics data dictionary table data with the NFM-P?. This procedure applies to all availability reports; it can be skipped if it has already been done.

Optionally, you may populate the maintenance window table in the auxiliary database with details of object maintenance; see To add data to the samdb maintenance-window table in an auxiliary database. The report runs if the table is not created or empty; however, maintenance windows are treated as downtime when availability is calculated.

Attributes to track operational state changes

The following table contains the attributes for tracking operational state changes.

Note: The table does not need to be manually enabled as it is system wide; by default, it is enabled for the entire network. Therefore, no action is required to enable the table. The current database sizing tool does not account for availability reports, and the retention time is not configurable. The availability reports are limited.

Table 11-18: Attributes to track operational state changes

Dictionary Name	Input Parameter	If State Changed	If State Not Changed
analytics_bundleInterface	operationalState	Returns 1	Returns 0
analytics_lagInterface	operationalState	Returns 1	Returns 0
analytics_PhysicalPort	operationalState	Returns 1	Returns 0
analytics_Sts12Channel	operationalState	Returns 1	Returns 0
analytics_ScadaPort	operationalState	Returns 1	Returns 0
analytics_rtr_ntwInterface	operationalState	Returns 1	Returns 0
analytics_business_aa_sub	operationalState	Returns 1	Returns 0

Report characteristics

The following table lists the principal report characteristics.

Table 11-19: Ports and Interfaces Availability Summary 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 minutes (minutes, min), hours (hours, h), days (days, d), weeks (w), or months (months, m)
	Granularity	Aggregation types: None (raw data) 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.
	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	Yes—Click on a KPI in a table cell to launch the Details report

Notes:

Note: The 7705 SAR-H is not supported.
