Managing vCenter Permissions for Pure1 VM Analytics

For the un-initiated, Pure1 VM Analytics is a tool where you can deploy a collector and authenticate it with one or more vCenters. That collector then sends performance and topology data back to Pure1. We then display it in an easy-to-understand view to help you view your end-to-end environment. Identify performance bottlenecks, heavy hitters, whatever.

For this to work, the collector needs authentication to vCenter of course, but not a lot. Read Only will do. If you want it to see the entire vCenter and every object, the simplest option is to create a new user, and assign it read-only permissions to the vCenter object and propagate it down to everything:

Then select your user, choose read only and make sure to select “Propagate to Children”

Pure1 REST API Authentication Made Easy

I’ve been working with the Pure1 REST for about a year now and have really enjoyed what it brings. I’ve integrated it into a few things: PowerShell. vRO. vSphere Plugin. One of the “tricky” things about it though is the authentication. Instead of a username and password it requires the use of a RSA256 public/private key pair. This is inherently more secure, but of course requires a bit more know-how when it comes to pair generation.

I simplified a fair amount of it in PowerShell, but didn’t quite get to the finish line. The generation of the key pair could be done but it came in the form of a PFX–which basically combines the public key and private key into one file. Unfortunately, Pure1 requires the them to be separated as all it needs is the public key, not your private key. While this is “better” it does leave Windows users at a bit of a disadvantage–there is no built in mechanism to generate this without installing OpenSSL directly. The process could not be done entirely in PowerShell. Or so I thought…

VM Analytics Collector Now an OVA

Hear ye, hear ye! The VM Analytics Collector now comes in a new flavor! And OVA! Yay! I understand this is more of a “about time, why didn’t you have this in the first place?” kind of a thing, and fair enough, but here we are.

Now the current OVA is somewhat a shadow of what we expect it to be, a lot of the work that went into this was to build the ground work to use this for many other things. So certainly expect this to be developed and offered in more advanced and flexible ways. But for now, it is an OVA that is locked down that contains one thing: the collector.

No, not that collector. The vCenter collector for our VM Analytics tool.

  • ActiveCluster support
  • Enhanced protection group information
  • Throughput limits
  • Volume Groups
  • Pure1 REST API integration
  • Protocol Endpoints
  • Host Personality

Using the Pure1 PowerShell Module

Recently I wrote a blog post on how to authenticate and connect to Pure1 via PowerShell. You can find that here:

I have made authentication MUCH easier:

But it is fairly involved, so I made it easier for you (and me) by writing a PowerShell module and posted in on the PowerShell Gallery.

Using the Pure1 REST API Part I: PowerShell

In my last post, I spoke about the ins and outs of using the Pure1 REST API–but it was a fairly manual process. Which of course is not how you really want to use a REST API. So the first part of this series will be using it with one of my favorite tools: PowerShell!

I will separate this into five parts:

  1. Creating your certificate
  2. Adding your public key into Pure1
  3. Creating your JWT
  4. Authenticating with Pure1
  5. Making REST calls after authentication

UPDATE!!!! I made this much easier, you can use my module to connect to Pure1 which is on the PowerShell gallery.

You can find more information on it here:
