It's intuitive and user-friendly. It can be a bit painful to deploy. Product provides excellent overview across physical and virtual networks in your virtual environment . In large organizations where vSphere / SDDC / Private Cloud deployments have thousands of VMs and network segments that product definitely bring significant benefit in terms of monitoring, troubleshooting and granular details of network deployment and traffic of connected devices (physical or virtual ) and last but not least holistic view of your network domain.
The gradual way the Network Insight shows you all the relevant information about your networks. It's pretty good. You can really dig deep deep inside and see where the problem is, where it comes from, what you have inside, how did you configure it. Also, it has alerts so you can have pretty much quite a big overview about your network. This is really something good.
I would give 7 to 8. There is always room for improvement.
Deployment process ,Appliance and Proxy VM, is getting configuration done in VM Console. This configuration can definitely be done on web interface (e.g. vROPS) for sake of simplicity and admin sanity.
LDAP / Active Directory integration configuration is not straight forwards as with other products on vRealize portfolio
Roles and User permissions configuration differs from other products, and in scenarios where certain group of individual need to have specific permissions across vRealize products configuration is not out of the box.
Clustering across Geo locations (Dual Site scenarios or different L2 Domains) or any other mechanism that can provide HA or maintain data availability across sites.
Offering few sizes of deployment would benefit customers that don't have big foot print in on-prem or cloud, but still would like to get the product into their infrastructure, for whatever reason. Current size of the virtual appliance is not suitable for small and medium size environments.
You can deploy proxy VMs, so it means that if you need to monitor different segments or different deployments of NSX you always can deploy a proxy VM and then monitor those networks within your vRealize Network Insight.
I have never actually had a chance to talk with the technical support about the product, but I assume they are brilliant.
We did not. Since the NSX footprint growth in data centers the majority of the cloud providers who are the companies start looking for something to have more gradual detail on the infrastructure in how the network goes and what the network traffic is, so it's better for troubleshooting, better for holistic overview of your network infrastructure. Before that, we didn't use anything. That's why the troubleshooting was a bit difficult.
It is straightforward. You need to have an IP address. You don't need to do any additional configuration of the appliances, but once you deploy the appliances then you need to do the configuration on the cause-all, which I think it's a bit more not that straightforward and not that intuitive. It could be better to have the initial configuration of the pliers to be over a web interface or some other wizard.
