Unable to add VNA gateway to Netops Portal low scale environment

Products

• CA Performance Management - Usage and Administration

Issue/Introduction

We stood up a VNA server recently and want to add it to NetOps Portal, however the "New" button is grayed out on the Administration > Monitored Items Management > VNA page.  The environment is a low scale environment

Environment

Dx NetOps Performance Management any version

Cause

Not supported in a low scale environment

Resolution

See the following documentation:

https://techdocs.broadcom.com/us/en/ca-enterprise-software/it-operations-management/performance-management/23-3/installing/install-a-low-scale-system.html

 

... under the Limitations section

 

"Integration with DX NetOps Mediation Manager or DX NetOps Virtual Network Assurance"

 

So this is a limitation of the low scale environment. The reason we block this in a low scale environment is because this would very likely generate more than 150k polled items which is a limitation in a low scale environment.  The DC would need resources to process VNA data, which if the box is supporting DA and DC  - that means it has to share resources

Setting up what amounts to a "normal" environment, with each piece (DC, DC, DR, PC) on its own box would remove such limitations, and everything should work after that.
