Add a VMware vCenter Server

This module consists of the following exercises:

Add Your vCenter Server

1. In the Uptime Infrastructure Monitor Web interface, begin by clicking Infrastructure.
2. Begin adding your VMware vCenter Server as an Uptime Infrastructure Monitor Element. In the Infrastructure view, click Add System/Network Device.
3. In the Add System window, select VMware vCenter Server from the Type of System/Device drop-down. This reveals configuration fields specific to this type of monitored Element.
4. Complete the fields similar to those below:
   
   
   • The Display Name is used throughout the Uptime Infrastructure Monitor interface, as well as reports.
   • The Description can contain any extra information such as the version number or IP address.
   • The Options fields tell Uptime Infrastructure Monitor how to find and access your vCenter Server.
   • The Group fields allow you to sort virtual machines and ESX host machines.
   • You can leave the vSync Settings options at their defaults.

   Stick to the Basics

   By default, the Collect Uptime Agent data check box is clear. For this exercise, clear the Collect WMI Agentless data check box as well. This means the metrics Uptime Infrastructure Monitor retrieves for each monitored VM is what the vCenter Server itself collects and provides to Uptime Infrastructure Monitor. For these "basic VMs," their metrics are a subset of what can be collected from the guest operating system using the Uptime Infrastructure Monitor Agent or using WMI. For simplicity in this guide, we work with a "basic" vCenter Server inventory. You can learn more about agent- and WMI-based data collection in the next module, where you are adding physical servers.

5. Click Save. Uptime Infrastructure Monitor searches for your vCenter Server and import its inventory of ESX hosts and VMs as Uptime Infrastructure Monitor Elements. This can take a minute or more, depending on how large your vCenter inventory is.
   
6. Uptime Infrastructure Monitor informs you when the vCenter Server is added:
   
   Click Done to close the Add System window. 

Validation Step 1 > Explore the Monitored Inventory

After adding the vCenter Server and closing the Add System window in the previous section, the main UI window is displaying the Infrastructure view:

If you look at your Uptime Infrastructure Monitor inventory, you can see that part of the vCenter Server import process included the automatic creation of two top-level Element Groups (which are folders and subfolders used to organize Uptime Infrastructure Monitor Elements): Discovered Hosts and Discovered Virtual Machines. These Element Groups respectively include the ESX hosts and virtual machines managed by the vCenter Server, and these contents can be further rearranged in Uptime Infrastructure Monitor, for example, by platform or server function.

Alongside this pair of Infrastructure Groups, the vCenter Server itself appears as a top-level Element in Infrastructure. It includes the hierarchy of objects that comprise the vCenter Server inventory. Click the + icon beside your vCenter Server to expand its view.

Consider this example vCenter, which includes a datacenter:

In the above example, the datacenter's cluster of ESX hosts is organized into two resource pools, along with their component virtual machines. Hosts and virtual machines can be moved elsewhere in Infrastructure, but the hierarchy remains intact as a reflection of the vCenter Server:

Validation Step 2 > View the vCenter Server Inventory

This validation step can be particularly enlightening if your vCenter Server import exceeded your license, and resulted in automatic exclusion of ESX hosts and VMs from the monitored inventory in Uptime Infrastructure Monitor.

1. While in the Infrastructure view, click the vCenter Server's gear icon, then in the pop-up menu, click View.

2. In the left menu, the Info tab is active. Click Inventory Detail.
   This displays a list of all of your vCenter Server's inventory, grouped hierarchically. It is divided into two main groups: Elements that are monitored by Uptime Infrastructure Monitor, and Elements that are currently ignored. Initially, during the vCenter Server import, hosts and VMs that were imported after the Uptime Infrastructure Monitor license was exceeded were placed in the Ignored Elements section. You can use this Inventory Detail view to ignore monitored Elements, and begin monitoring currently ignored Elements. 

   Pro Tip

   You can also use this Inventory Detail view to Enable Monitoring for a vCenter Server Element. This can be done when an Uptime Infrastructure Monitor Agent is installed on a VM, allowing Uptime Infrastructure Monitor to collect metrics that are more detailed than what is provided by the vCenter Server.

Validation Step 3 > View Metrics for the vCenter Server and a VM

1. Click Infrastructure.
2. Click the vCenter Server's gear icon, then in the pop-up menu, click Graph Performance. Whenever you take this action with an Element, you are taken to its Quick Snapshot.
   Whenever you graph the performance of an Element from the Infrastructure view, its Quick Snapshot is displayed. What exactly is shown depends on the type of Element, which we see throughout this part of the Getting Started Guide. In this case, the vCenter Server's Quick Snapshot shows datacenter-level information that is directly pulled from the vCenter Server metrics:
    
   You can incorporate these basic metrics into your Uptime Infrastructure Monitor monitoring plans (such as alerts or reporting). It's more likely, however, that your interest is with the virtual machines that are a part of the vCenter Server inventory.
3. Click Infrastructure to return to the main inventory view.
4. Expand the Discovered Virtual Machines Infrastructure Group, and click the gear icon for any of the VMs. In the pop-up menu, again, click Graph Performance to display that Element's Quick Snapshot. This displays metrics for the VM that are pulled from the vCenter Server's metrics: 
   
   As with the vCenter Server Element's metrics, you can incorporate these into your alerts and reports. However, this "basic VM" view allows you to work only with what the vCenter Server provides; there may be cases where you want to add a little extra "Uptime Infrastructure Monitor power," and install an Uptime Infrastructure Monitor agent on the VM. This is something you learn a bit more about in the next module.
