How to get data for downed interfaces in NetOps Performance Management

Products

• CA Performance Management
• Network Observability

Issue/Introduction

It would appear that the default behavior is to suppress all historical interface data when the interface is admin down on a given device.

Environment

DX NetOps: All Supported Versions

Cause

The default component filter on the Network Interface Monitoring Profile is set to:

Administrative Status does not equal down(2)

By default we do not synch filtered interfaces to NetOps or odata API.
 

Resolution

Create your own Monitoring Profile (MP) with its own filter that doesn’t filter down interfaces.

In this way, Performance Management (PM) can continue polling them even when down.

And they will remain synced with NetOps Portal unless it fails whatever new filters are applied.

NOTE: Use the MP with care, applying only to mission critical devices and carefully monitoring how many i\f’s are added and what impact it has.
