Interface Data Retrieval for Administratively Down Interfaces in DX NetOps Performance Management

Issue/Introduction

By default, DX NetOps Performance Management suppresses historical interface data when an interface is set to ifAdminStatus = DOWN.

This article outlines how to configure Monitoring Profiles to continue polling these interfaces for reporting and historical data access.

Cause

The default component filter on the "Network Interface Monitoring Profile" includes the following rule: Administrative Status does not equal down(2)

This filter prevents the synchronization of administratively down interfaces to the NetOps Portal or the OData API, effectively masking them from reporting views.

Resolution

To view historical data for downed interfaces, create a custom Monitoring Profile that overrides the default filtering behavior.

1. Navigate to the Monitoring Profiles section in the NetOps Portal.
2. Copy the default Network Interfaces profile.
3. Edit the new custom Monitoring Profile.
4. Remove or modify the filter criterion: Administrative Status does not equal down(2).
5. Save the changes and assign this new Monitoring Profile to the required mission-critical devices.

Note: Apply this Monitoring Profile carefully, as polling additional interfaces increases SNMP traffic, Data Collector load, and Data Aggregator storage usage.

Additional Information

Note: Apply this Monitoring Profile carefully, as polling additional interfaces increases SNMP traffic, Data Collector load, and Data Aggregator storage usage.

Try to limit the scope of the filter ideally to specific interfaces of interest.
