One of my favorite products has just dropped a new version. vRealize Network Insight 3.8 (vRNI) has just hit the downloads and has a bunch of cool new stuff.
vRNI 3.6 introduced a public API with which you can do most of the day-2 operations. vRNI 3.7 didn’t bring any changes to the API, but 3.8 does. Below are the changes in the API version 1.1.0.
Fetching info in bulk
Version 1.0.0 had endpoints to grab information from entities (VMs, hosts, firewall rules, etc), but it was a bit tedious. You had to request a paged list of entities … Read more
PowerShell is about making things easy and consumable. Same goes for PowervRNI, making repetitive tasks in vRealize Network Insight easier and make it possible to extract information from vRNI.
It’s not that easy to load a custom module into PowerShell though, you have to download 1 or 2 files, then load it into your PowerShell session by referencing those local files. The PowerShell Gallery is a pretty awesome way to also make module management very easy. All you have to do is use the Install-Module command and it downloads and installs the module for you.
For the module authors, … Read more
This is the second post in a series on how to use PowervRNI to manage Applications within your vRealize Network Insight environment. If you’d like to learn about managing Data Sources with PowervRNI, check here.
Introduced in vRealize Network Insight 3.2 in the begin of 2017, Applications are logical containers which can contain the structure of applications (including tiering). You can use these application containers to better visualize what network flows are going between specific applications or even application tiers. Next to insights into your applications, you can also use it to take a per-application approach to micro-segmentation, … Read more
This is the first post in a series on how to use PowervRNI to manage your vRealize Network Insight environment. Starting with Data Sources.
Brief background; data sources in vRNI are endpoints from which vRNI retrieves information from. Examples are: vCenter, NSX, Switches, Routers, Firewalls, an AWS account or converged infrastructure systems like Cisco UCS or HP OneView.
Adding data sources is usually only performed when vRNI is installed into the environment and every time a new endpoint is added to your environment (for example a new vCenter environment, or when a new switch is plugged in).… Read more
I am excited to introduce PowervRNI to the world! In the 3.6 release of vRealize Network Insight (vRNI) in November, there was a public API added. Through this API, you can offload certain tedious tasks like creating applications and managing data sources. I was using the private API for a couple of things already, like importing data sources. With the release of the public API, I could move those things to use the public (and supported) API. Ever since then, I’ve been working on PowervRNI.
The first release of PowervRNI is on GitHub here. With this … Read more
With the release of vRealize Network Insight 3.6, the flow analyser inside vRNI now supports external sources for NetFlow. This means you can perform micro segmentation planning on physical servers (before you migrate them to virtual) and create deep insight into what network traffic is going through your entire network (and not just limited to what’s happening in your virtual network).
Currently, NetFlow versions 5, 7, 9 and IPFIX are supported. Getting started with NetFlow in vRNI is pretty easy, but it is slightly more complicated than regular data sources.
I say it’s slightly more complicated, because … Read more
One thing that I absolutely love about vRealize Network Insight (vRNI) is that the entire database is open by default and that the search bar is powered by Elastic Search. That means that you can type in pretty advanced search queries and basically query everything that vRNI collects. The query itself is written in natural language, so you don’t have to be an expert to use it. You can get really creative as well, getting output you would have a hard time seeing without using the search. To give you some examples, below you can find my cheatsheet with searches … Read more
