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
CAPM 20.2
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 CAPC or odata.
Resolution
Create your own Monitoring Profile (MP) with its own filter that doesn’t filter down interfaces.
In this way, CAPM can continue polling them even when down.
And they will remain synced with CAPC 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.
