Integrating ServiceNow with Network Insight

In a previous post, Integrating vRealize Automation with Network Insight, I covered how greenfield applications can be automatically pushed into vRealize Network Insight to provide application context with the analytics of Network Insight. This post is about importing brownfield into Network Insight to get insights into the behavior of your existing applications. Specifically, importing CMDB information from ServiceNow.

CMDB

In the case of existing applications, your Configuration Management Database (CMDB) should be your source of truth. There are a lot of CMDB products out there, … Read more

Integrating vRealize Automation with Network Insight

In order to get a complete view of your network traffic flows between applications inside Network Insight, it should know things about your application stacks. This post will go into how to create an integration with vRealize Automation in order to get all new application stacks into Network Insight. This will happen on the moment that an application is deployed from a blueprint, instantly transferring info so every greenfield application will give context in Network Insight.

As you may know by now, Network Insight listens … Read more

Integrating vRealize Network Insight and Log Insight

Starting in version 3.8 of Network Insight, you can integrate vRealize Log Insight with Network Insight in order to get faster changes in the NSX environment.

Polling vs real-time data

Currently, the collector of Network Insight polls NSX every 10 minutes for changes in the entities (security groups, tags, firewall rules, etc). It will also back off when the NSX Manager has too much load, extending the polling period and give the NSX Manager some breathing room. While this is generally okay for troubleshooting scenarios, it should be improved significantly for monitoring purposes where you need real-time data.

Using PowervRNI to configure SNMP settings on data sources

Version 1.2 of PowervRNI was just released and it contains 2 new cmdlets: 

  • Get-vRNIDataSourceSNMPConfig
  • Set-vRNIDataSourceSNMPConfig

You can use these cmdlets to see and update SNMP configuration on specific data sources. All Arista, Brocade, Cisco, Dell, and Juniper devices are data sources where SNMP can be enabled for richer data collection. This basically turns on interface counter collections, so you can have pretty graphs like this: 

Examples

To give you an idea of how to use these new cmdlets, check out the examples below. Of course, there is also documentation available in the module itself, viewable via the Get-Help cmdlet.

vRealize Network Insight 3.8 – What’s new in the API?

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

PowervRNI is now on PowerShell Gallery

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

Using PowervRNI to Quickly Add Applications

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.

Applications

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
