Are there any svm samples or documentation available for new Network Monitoring service in NSX T 2.5?
The sample available in the portal seems to be related to FW uscases only.
Are you talking about this part of the 2.5 release notes?
If it is, what this means is that NSX-T is now capable of integrating with partner SVMs leveraging packet copying. While NSX-T has this ability, partners have to go through testing and validation of their solutions. When this happens it will be posted here: VMware Compatibility Guide - Networking and Security Services for NSX-T
The compatibility guide is where you should look and where approved integrations are published. Now with this new possibility using packet copy new integrations should developed and when they are ready they will be published in the compatibility guide.
