vCenter Server plug-ins extend the capabilities of vCenter Server by providing additional features and functions.

Some plug-ins are installed as part of the base vCenter Server product.

vCenter Storage Monitoring
Allows you to review information on storage use and to map relationships visually between all storage entities available in vCenter Server.
vCenter Hardware Status
Uses CIM monitoring to display the hardware status of hosts that vCenter Server manages.
vCenter Service Status
Displays the status of vCenter services.

Some plug-ins are packaged separately from the base product and require separate installation. You can update plug-ins and the base product independently of each other. VMware modules include:

vSphere Lifecycle Manager
Enables administrators to apply updates and patches across ESXi hosts and all managed virtual machines. Administrators can create user-defined security baselines that represent a set of security standards. Security administrators can compare hosts and virtual machines against these baselines to identify and remediate systems that are not in compliance.
vRealize Orchestrator
A workflow engine that enables you to create and run automated workflows in your vSphere environment. vRealize Orchestrator coordinates workflow tasks across multiple VMware products and third-party management and administration solutions through its open plug-in architecture. vRealize Orchestrator provides a library of workflows that are extensible. You can use any operation available in the vCenter Server API to customize vRealize Orchestrator workflows.
