Discovering Nutanix clusters in OpManager

Nutanix is a vendor of distributed computing and storage virtualization solutions, specialising in an area called 'Hyperconverged Infrastructure'. Basically, the idea is to provide an all-inclusive virtual environment, including the storage component of the VM itself. This is to enable data requests to be handled inside the VM itself instead of being sent to an external storage, and so the latency for data retrieval and access reduces to a negligible level.

OpManager makes use of the Prism API framework to fetch performance metrics from the devices in the Nutanix environment.

Discovering your Nutanix cluster into OpManager

  1. Enter the IP address or DNS name of the Nutanix cluster.
  2. From the Nutanix Credential drop-down, select an existing credential profile.
  3. If the required credential profile is not available, click Add Credential. In the Add Credential (Nutanix) window, provide the following details:
    4. FieldDescription
    Profile NameName of the credential profile
    DescriptionBrief description of the credential profile
    User NameUser name of the Prism Element
    PasswordPassword of the Prism Element
    ProtocolSelect HTTP or HTTPS
    Time OutConnection timeout value (default: 20 seconds)
    Port NumberPort used by the Prism Element (default: 9440)
  4. Click Save to create the credential profile.
  5. To enable in-depth monitoring of hosts and virtual machines, click Advanced Settings and select the required credential profiles:
    • SNMP
    • WMI
    • CLI
  6. Click Discover to start discovering the Nutanix cluster.
  7. In the Discovered Devices screen, OpManager lists all hosts and virtual machines under the specified Nutanix cluster.
    • Hosts will be discovered by default.
    • Select or clear the checkboxes to choose the virtual machines that need to be monitored.
