Last week VMware warninghas silently removed the download for the latest version of VMware NSX. Today the Support Insider blog, which is a great resource for first-hand field experience, reported that the NSX for vSphere 6.2.3 release has been officially pulled.

Additional USB NIC for Intel NUCs running ESXi

Intel NUCs with ESXi are a proven standard for virtualization home labs. I'm currently running a homelab consisting of 3 Intel NUCs with a FreeNAS based All-Flash Storage. If you are generally interested in running ESXi on Intel NUCs, read this post first. One major drawback is that they only have a single Gigabit network adapter. This might be sufficient for a standalone ESXi with a few VMs, but when you want to use shared Storage or VMware NSX, you totally want to have additional NICs.


A few month ago, this problem has been solved by an unofficial driver that has been made available by VMware engineer William Lam.

Deploy VMware NSX-V in Homelabs with Limited Resources

downsizing-nsxWhen deploying VMware NSX-V in a homelab, its huge resource requirement might be an issue. In the default configuration a small setup with NSX Manager, 3 NSX Controllers and 2 Edge gateways requires 30 GB Memory. Consumer VMs to connect to logical switches requiring additional resources.

This post explains how you can deploy VMware NSX in your homelab with less than 8GB Memory by downsizing each component including:

  • NSX Manager
  • NSX Controllers
  • NSX Edge Gateways

Send dvSwitch Port Statistics to Graphite

For network analysis I want to have Distributed Switch port statistics in my Graphite installation. I’ve created a script that pulls dvSwitch port statistics from a vCenter server, or directly from an ESXi host and sends them to a Carbon Relay. Ports connected to NSX Logical Switches, which are actually distributed Port Groups, are also included. This allows to create universal dashboards with Grafana for example.


This script is intended to run as cronjob every minute. Port Statistics are provided as counters which can be easily converted to per second values with Graphite functions.

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.

In this example I'm running 3 nginx web servers on small Linux appliances connected to a logical switch.
