VCF Upgrade Failure with Static NSX-T Routing

Do you have a VMware Cloud Foundation infrastructure that’s using NSX-T to statically route network traffic between the NSX-T Edges and the physical network? If so, you can be faced with this error when attempting to upgrade VCF via the SDDC Manager:

2022-04-19T18:28:58.205+0000 ERROR [vcf_migration,0000000000000000,0000] [c.v.e.s.o.model.error.ErrorFactory,pool-5-thread-12] [43TCDO] TIER_0_ROUTE_DISTRO_UPDATE_POST_VALIDATE_FAILED Post-validate of tier-0 T0
route distribution types update failed com.vmware.evo.sddc.orchestrator.exceptions.OrchTaskException: Post-validate of tier-0 T0 route distribution types update failed

This is a quick post with the solution to that error. It seems like VCF is mostly designed for dynamic routing via BGP (which makes total sense), with which routing redistribution is necessary … Read more

Transferring Applications between vRealize Network Insight instances

Let’s say you have multiple vRealize Network Insight instances. Maybe a staging instance for trying new searches, alerts, or other configuration – and a production instance. Or you’re migrating from an on-premises instance to a vRealize Network Insight Cloud instance. Or you just want a backup of the hard work you put into curating the applications. As with many things; there’s an API and script for that!

Python SDK & Examples

The Python SDK is a library generated automatically by the OpenAPI specification that vRealize Network Insight has baked in. In addition, it has a ton of example scripts that … Read more

Integrating vRealize Automation Cloud & vRealize Network Insight Cloud

When you have vRealize Automation in place to deploy applications, vRA is the source of truth when it comes to the application landscape. It makes sense to treat it that way, and not have other products (like vRealize Operations or vRealize Network Insight) have to discover those newly deployed applications on their own. Which is what this post is about!

Before you continue, I’ll not be going too deep into vRA, vRNI, or the Extensibility in vRA that makes this happen and assume you know the basic of those products and features. This post explain how to get your vRA … Read more

vRealize Network Insight Cookbook Update

It’s been a while since I posted about the vRealize Network Insight Cookbook. Honestly, the pandemic and other events over the last two years drained my creativity, especially in writing. The goal was to update it with new features every six months, and add more of the big ticket items (like SD-WAN, Network Assurance and Verification) continously. More than a year and a half later, I can say that that plan failed. 🙁 

However! My writing creativity seems to be getting back to some resemblance of what it was and I’ve started updating the digital cookbook. 🙂

Event-Based Automation with vRealize Network Insight & VEBA

With the release of vRealize Network Insight 6.4 – something awesome was added: the databus. In its essence, the databus is a feature that exports data out of vRNI using REST API webhooks. These webhooks deliver the data over HTTP[S] to an endpoint that can then parse and process the data. There are several message groups, which you can subscribe an endpoint to. The message group decides what type of data is exported and with the initial databus feature, you can subscribe to: Application updates (newly discovered, updated, or deleted apps), and Problems (alerts). The latter open up event-based … Read more

vRealize Automation Action – SSH to Servers Post-Deployment

In the VMware CMBU lab, I built something cool that I wanted to share. Creating a demo for vRealize Network Insights featured called Flow-based Application Discovery, I needed to get applications running in the lab to dynamically resize from time to time. In a demo three tiered application; add one or two web or app servers, or remove them. Flow-based application discovery would then detect the change and suggest updating the application in Network Insight. 

One of the requirements is that there has to be traffic going between all servers before application discovery picks it up. That’s what led me … Read more

Natural Language Searches with PowervRNI

vRealize Network Insight 6.3 brought a new API endpoint: /search/ql. The QL stands for Query Language, which is the same language that’s used in the search bar. I added support for that endpoint in PowervRNI 2.0 with the cmdlet Invoke-vRNISearch. With this post, I’d like to explain why that’s the best since sliced bread. 😉

Previously, there was the /search API endpoint, but that used an internal query language. You would run a search in the vRNI interface, open up the browser Developer Tools and look for the internal query that went against the vRNI backend. You could … Read more
