DX NetOps CA Virtual Network Assurance CA Performance Management - Usage and Administration


When we initially set up the VNA Gateway, we used the existing Data Collector.  Now, we've set up a dedicated Data Collector for the VNA Gateway.  However, I cannot modify the VNA Gateway configuration document to point to the new Data Collector

How to change Data Collector (DC) used by Virtual Network Assurance (VNA) in DX NetOps Performance Management Portal web UI.


All supported DX NetOps Virtual Network Assurance releases


No code exists to support functionality allowing movement of VNA items tied to one DC to another.


The only solution at this time is to delete the existing Gateway and configure a new one using the new Data Collector (DC).

This will result in the existing VNA generated non-SNMP managed items tied to the existing DC being deleted, along with their historic data being removed.

The same items should then be rediscovered through the new Gateway/DC association where polling should resume.

Adding this functionality would require submission of an Enhancement Request. To do so open a Support case for additional details.

Caution: It is not recommended to disable the existing VNA Gateway, and adding a new one for the same plugins and new DC. That will result in duplicate items which will cause additional VNA data collection issues.
