Visualizing live network traffic on the vCenter Server Appliance using net-glimpse

07.17.2017 by William Lam // 2 Comments

Last week I came across a really interesting OSS project called net-glimpse which allows you to easily visualize your network traffic in real-time and making that available using any standard web browser. I thought it would be neat to see what this might look like running on the vCenter Server Appliance (VCSA). I got it up in running in just a couple of minutes and even shared the results on Twitter as you can see from the tweet below:

I had couple of folks ask about the setup and I figure I would post a quick write up. While looking at the project, I found that net-glimpse includes quite a bit of customizations in the colors, data collection and how data is displayed. Specifically, rather than relying on the well-known ports that have already been pre-defined, you can also add additional custom ports and specify the label that it should automatically used. This gave me an idea, instead of a generic visualization of the VCSA, we could get specific service information and have those label automatically get displayed.

VMware Validated Design (VVD) & VMware Cloud Foundation (VCF) Quick References

05.02.2017 by William Lam // 2 Comments

The other day, I had a customer ask about the latest version of the Ports and Protocols document that was put together by the VMware Validated Design (VVD) team which does a fantastic job of outlining all the connectivity between the products used within the VVD SDDC. It actually took me awhile to find after realizing it was posted on the VMTN Community rather than the official documentation page.

I also came across other VVD content that I thought would also be useful for customers and decided to create a VVD "Quick Reference" that organizes all of this content into a single place. In addition, I also created a nice short URL to the quick reference so you only have to remember that. After sharing this on Twitter yesterday, Ryan Johnson (TMM for VVD/VCF) got inspired and also created VMware Cloud Foundation Quick Reference which I also built a short URL for. If there is other content that you would like to see, feel free to drop me or Ryan a comment or better yet, submit a pull request on the Github page!

To access the Quick References, use the following short URLs:

  • https://github.com/lamw/vvd-quick-reference
  • https://github.com/ftwegner/cloudfoundation-quick-reference

Below is a quick screenshot of both the VVD and VCF Quick References:
