Discovering VMware ESX servers in OpManager

To discover the host and the VMs, you just need to provide the IP Address and https credentials of the host. The VMs are automatically discovered along with the host.

Steps to discover the Host and VMs

Before proceeding ensure that you have configured the VMware credentials for the Host, and SNMP and WMI credentials for the VMs in the Credential Library. To configure the credentials

  1. Go to Admin-> Credential Settings and click New button.
    add-credentials
  2. Select VMware as the Credential type and enter the Host Name and its HTTPS Username and Password.
  3. Enter the HTTPS web service port number and timeout interval for the connection between the Host and OpManager server.
  4. Click Add to add the credential.

Similarly, add the credentials for the VMs. Select the Credential Type as WMI for Windows and SNMP for non-Windows OS.

To discover the host:

  1. Go to Admin-> Add Device. (You can also access the Add Device window from Maps-> Virtual Devices-> Add New Host).
  2. Enter the Host Name / IP Address.
    add-host
  3. Enter the correct Netmask and select the appropriate credentials.
  4. Click Add Device button to add the host.
If  any of the VMs  are already discovered or added, OpManager automatically maps them as Virtual Device. Once the discovery is over you can find the Host & VMs under 'Virtual Device' category in Maps tab.

Note: If the device has been added successfully, but not displayed under the Virtual Devices map, search for that device. Go to its snapshot page and look for the device type. If it is mentioned as ‘unknown’, wrong credentials might have been provided or it is not reachable during discovery. Provide the correct credentials and click on ‘Rediscover Now’ under Actions tab in the snapshot page, to discover it as an ESX host.

Configuring VM IP Address

OpManager, with the help of installed VMware Tools, identifies the IP address of the VM and maps it to the host. In case the VMware Tools are not installed, OpManager discovers it using VM's entity name. You can assign the IP address for such VMs in the host snapshot page (screenshot of the same is given below). Click on the 'No IP Address' link corresponding to the VM to assign the IP address for that VM. Similarly, you can click the assigned IP address to choose another one as the primary IP for that particular VM.

Assign or Change VM IP Address

Manage or Unmanage VMs

You can now choose to monitor only the required VMs on a Host. OpManager discovers all the VMs during the initial discovery and you will find them listed under the inventory in the host snapshot page. Click on the relevant icon to monitor the required VMs on the host. OpManager maintains this configuration when a HA, VMotion, or rediscovery happens.
