Exploring new VCSA VAMI API w/PowerCLI: Part 2

01.25.2017 by William Lam // 14 Comments

In Part 2 of this series, we take a look at how to monitor the health of your vCenter Server Appliance (VCSA) by retrieving some of the health metrics that are exposed by the Virtual Appliance Management Interface (VAMI).

VAMI UI Area of Focus

Regardless if you have an Embedded VCSA, External PSC or External VCSA node, there are four basic health metrics that are shown in the VAMI UI today: overall health of the system, CPU, memory and the last time the health check was performed. If you are running an Embedded VCSA or External VCSA, there is an additional health metric for the vCenter Server Database (VCDB) as shown in the screenshot below. Interestingly, while going through the health APIs, I also found a few more metrics that are currently not displayed in the VAMI UI today. These additional metrics include Swap, Storage and Software packages which can also be useful to monitor, especially on the storage front.

Exploring new VCSA VAMI API w/PowerCLI: Part 1

01.23.2017 by William Lam // 11 Comments

One of the most most exciting developments in vSphere 6.5 with respect to Automation is the introduction of several new REST APIs included in the vCenter Server Appliance (VCSA). In addition to covering some of the existing capabilities like vSphere Content Library and Tagging, customers will now have access to a new basic Virtual Machine management API that has been greatly simplified compared to the traditional vSphere SOAP API and access to the VCSA's Virtual Appliance Management Interface API, also known to most as the VAMI.

I am particular excited about the VAMI REST API as this is where customers will be able to manage the entire full lifecycle of their VCSA/PSC which will eventually include all Day 2 operations as well as Install, Upgrade, Migrate and Recovery capabilities. This initial release of the VAMI REST API covers most of the functionality found in the current VAMI UI by going to https://[VCSA]:5480 after your VCSA or PSC has been deployed.

Not having spent a whole lot of time with the new VAMI REST API, I figured a good way for me to learn more about the APIs was to consume it and what better way than using PowerCLI? With PowerCLI 6.5 R1 (Windows version) release, there is a new Connect-CisServer and Get-CisService cmdlet that provides you access to these new REST APIs including the VAMI APIs. As I explore the new VAMI APIs, I plan to create a new VAMI PowerCLI Module that contains functions exerising some of the new APIs that you see today in the VAMI UI.

How to automate the deployment of an un-configured VCSA 6.5 (Stage 1 only)?

12.19.2016 by William Lam // 2 Comments

In vSphere 6.5, the VCSA deployment has changed from a "Single" monolithic stage where a user inputs all of the required parameters up front and then the installer goes and deploys/configures the VCSA. In the new VCSA UI Installer, we still continue to provide a "Single" monolithic user experience but behind the scenes, the deployment is now actually composed of two distinct stages, creatively called Stage 1 and Stage 2.

  • Stage 1 - Initial OVA deployment which includes basic networking + OS password
  • Stage 2 - Applying the VCSA specific configurations (e.g. External Platform Services or Embedded VCSA)

One reason why this is so useful is that in previous releases of the VCSA, if you had fat fingered say the DNS entry or wanted to change the IP Address/Hostname before applying the actual application configurations, your only option was to re-deploy the VCSA, not a very good user experience. With this new deployment model, customers now have the ability to either go through both Stage 1 and Stage2 or they can stop just after Stage 1 which would allow them to make necessary edits before continuing to Stage 2. If you decide to stop after Stage 1, then to complete the deployment, you will need to open a browser and finish the configuration using the VCSA's Virtual Appliance Management Interface (VAMI) at https://[VCSA-HOSTNAME-OR-IP]:5480

Once on the VAMI UI, you will want to select the "Set up vCenter Server Appliance" which will then launch the configuration wizard. From here, you will have the option of changing some of the settings that you had provided in Stage 1 such as the IP Address or things like NTP or enabling SSH access as shown in the screenshot below. Once you have confirmed these settings, it will be saved and then you will move onto Stage 2 to complete the configuration of your VCSA deployment.
