Alarm whitelist types are not working in VNA, other non-whitelisted alarms appearing

Products

• DX NetOps
• CA Virtual Network Assurance

Issue/Introduction

Setting up whitelist filter in Virtual Network Assurance (VNA) to allow through only specified alarms as per:

KB : How to Filter Cisco ACI Faults by fault code from VNA

However, alarms not in the whitelist are also appearing in Spectrum. How can this be fixed?

Environment

DX NetOps VNA integrated with Spectrum, releases 22.2.x or later

Resolution

You can run the following query in the MySQL DB:

select distinct name from notifications where notificationType="ALARM";

This will give the fault codes which are processed. If you see those fault codes coming through which are not in the whitelist, then you can apply a global filter from the swagger UI.

The Notification filter should be applied per Engine ID, so you can apply different filters across different Engine IDs. For example, 3 separate filters, each targeted against a different engine ID.

You can access the Swagger UI and setup filters as per the following documentation:
