Discovering VMware ESX/ ESXi servers in OpManager Plus

To discover the host and the VMs, you just need to provide the IP Address and https credentials of the vCenter/ Host. When you provide the vCenter credentials, all the host and VMs managed by that particular vCenter will be discovered. In-case of providing the Host credentials, the host along with its VMs are discovered.

Steps to discover the Host and VMs

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

  1. Go to Admin-> Discovery -> Credential Settings and click Add Credential.
  2. Select VMware as the Credential type and enter the vCenter/ Host Name and its HTTPS Username and Password.
  3. Enter the HTTPS web service port number and timeout interval for the connection between the vCenter/ Host and OpManager Plus server.
  4. Click Save 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 vCenter/ Host:

  1. Go to Admin-> Discovery-> Add Device.
  2. Enter the Device Name / IP Address.
  3. Enter the correct Netmask and select the appropriate credentials.
  4. Click OK button to add the vCenter/ host.

If  any of the VMs  are already discovered or added, OpManager Plus automatically maps them as Virtual Device.

Note: If the device has been added successfully, but not displayed under the Virtual Devices, search for that device. Upon finding the particular 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’ present under three line menu at the top right corner in the snapshot page, to discover it as an ESX host.

 

Configuring VM IP Address

OpManager Plus, 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 Plus discovers it using VM's entity name. You can assign the IP address for such VMs in the host snapshot page. Click on the Edit device details present under three line menu icon at the top right.

Manage or Unmanage VMs

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