Topology of the Virtual Infrastructure

This page appears when a managed virtual server listed in the VIRTUAL SERVERS page is clicked.

This page can also be accessed by clicking on the VIRTUAL TOPOLOGY link in either of the following pages:

  • the page displaying the layer model of a managed virtual host
  • the page displaying the layer model of a server application executing on the managed virtual host
This page makes it easier for the administrators to visualize which applications are sharing resources from each hypervisor (virtual server/host). In addition, this page enables tracking application-to-VM dependency by providing the IP address and operating system of the virtual machine for each application. This way, administrators get a single pane-of-glass view of the application workload on the hypervisor.

Once a virtual host is managed, then using its built-in AutoVirtualMapping capability, eG Enterprise automatically finds out which of the managed server applications are executing on the virtual machines hosted by that host, and then, instantly establishes an association between that virtual host and the discovered server applications. This page depicts this automatically discovered association. For the automatic mapping feature to work, the detailed diagnosis frequencies set globally should not be set to 0:0.

This mapping of applications to virtual hosts is used by eG Enterprise for correlation - e.g., since the application runs on the virtual host, chances are that a problem with the host is going to impact the performance of the application running on one of the guests.

If need be, you can even disable the AutoVirtualMapping capability. This can be achieved by editing the eg_external.ini file (in the {EG_INSTALL_DIR}\manager\config directory). By default, the AutoVirtualMapping flag in the [MISC] section of this file is set to true. To disable the capability, you can set this flag to false. In such a case, once a virtual host is added, when adding any new server application using the eG administrative interface, you will be prompted to manually set an association between the server application being added and the virtual host.

Clicking on a server application or the virtual host in this page reveals the corresponding layer model, tests, and measurements.

Clicking on the Click here for VM Details button in this page opens the VM DETAILS pop up window that lists the VMs associated with the virtual host, the IP address of each VM and the operating system of each VM.

Moreover, if you navigate to the virtual topology page from the service topology, then by default, the virtual topology page will only display those virtual applications on the hypervisor that are engaged in delivering the monitored service. By just selecting the Show VMs from Other Services check box in the virtual topology page, you can view even those virtual applications that are not part of the service offering but are running on that hypervisor.
