NSX-T: Client 'admin' exceeded request rate of 100 per second.

NSX-T: How to create a Principal Identity

In NSX-T, you can't create local users. Except for the three default users admin, root, and audit, you have to connect to an LDAP server or integrate NSX-T with VMware Identity Manager to authenticate with additional users.

Send NSX Edge Gateway Statistics to Graphite

To monitor VMware NSX Edge Gateways I want to send interface statistics to my Graphite installation. NSX Manager comes with a REST API that allows to pull information in XML or JSON format. I've created a script that pulls Interface, Firewall and Load Balancer statistics from all ESGs and sends them to a Carbon Relay. This allows to create universal custom dashboards with Grafana for example.
