Discovering and registering assets in a virtual environment
As an administrator of a virtual infrastructure, you want to know the state of the virtual machines in your environment at any given time. With TrueSight Server Automation, you can discover the virtual infrastructure inventory, and automatically register each discovered host server and virtual system as a managed server in TrueSight Server Automation.
Creating and executing a Virtual Infrastructure Discovery Job ensures that all virtual assets in the environment are known to TrueSight Server Automation, which results in the following benefits:
Managing the VM — Having a virtual machine registered in TrueSight Server Automation as a managed server enables you to view operating system-specific information about the virtual machine, and provides the ability to run Snapshot, Audit, and Compliance Jobs against that information. In addition, you can browse and manage the operating system and application-specific aspects of the virtual machine directly through the TrueSight Server Automation Console.
If an RSCD agent is not installed on the VM, the Virtual Infrastructure Discovery Job will still create a Server Object for the VM and you will need to install an RSCD agent on the system (for example, by creating and running an Agent Installer Job). This RSCD agent will enable you to manage the VM, that is, to perform operations such as running Snapshot, Audit, or Compliance Jobs, as you do on any other server.
- Controlling virtualization sprawl — Using the Virtual Infrastructure Discovery Job, you can identify any virtual machines that are contributing to virtualization sprawl. Virtualization sprawl is an uncontrolled growth of virtual systems, which leads to un-managed virtual systems that consume IT resources without being productive systems (for example, a virtual machine which is no longer associated with a host server, but still exists on the datastore). You can run a Virtual Infrastructure Discovery Job to query the environment for existing virtual machines, Solaris zones, or IBM virtual assets. Running the Virtual Infrastructure Discovery Job enables you to see what the virtual inventory looks like, without having to manually find and register each virtual asset. Being able to manage this inventory effectively enables you to control resource waste and optimize the use of the available hardware.
