VMware vSphere 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the vsphere monitor via the Smart Agent Receiver.

A VMware vSphere deployment includes physical hosts, ESXi hypervisors, virtual machines, and a vCenter Server.

To report metrics for a vSphere deployment, this monitor logs into a vCenter Server and retrieves data about the deployment and its real-time performance data on a regular interval.

When the monitor first runs, it logs in to the vCenter Server and traverses the inventory, gathering and caching all of the hosts and virtual machines and their available metrics.

After this initial sweep, the monitor will query the vCenter for performance data and metrics. This query takes place every 20 seconds, which is the interval at which the vCenter makes real-time performance data available. As a result, regardless of the intervalSeconds value in the agent configuration, this monitor will run every 20 seconds.

The monitor also refreshes, at a configurable interval, the cache of hosts, virtual machines, and metrics. By default, this refresh takes place every 60 seconds; however, this interval can be changed by updating the configuration field InventoryRefreshInterval.

This monitor uses VMware’s govmomi SDK, which officially supports vCenter 6.5, 6.7, and 7.0. While this monitor may work with vCenter 5.1, 5.5, and 6.0, these versions are not officially supported.

Note: When you add a custom role and do not assign any privileges to it, the role is created as a Read-Only role with three system-defined privileges: System.Anonymous, System.View, and System.Read. For more information, see Using Roles to Assign Privileges.

Installation 🔗

This monitor is available in the SignalFx Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector.

To install this integration:

  1. Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform.

  2. Configure the monitor, as described in the next section.

Configuration 🔗

The Splunk Distribution of OpenTelemetry Collector allows embedding a Smart Agent monitor configuration in an associated Smart Agent Receiver instance.

Note: Providing a vsphere monitor entry in your Smart Agent or Collector configuration is required for its use. Use the appropriate form for your agent type.

Smart Agent 🔗

To activate this monitor in the Smart Agent, add the following to your agent configuration:

monitors:  # All monitor config goes under this key
  - type: vsphere
    ...  # Additional config

See Smart Agent example configuration for an autogenerated example of a YAML configuration file, with default values where applicable.

Splunk Distribution of OpenTelemetry Collector 🔗

To activate this monitor in the Splunk Distribution of OpenTelemetry Collector, add the following to your agent configuration:

    type: vsphere
    ...  # Additional config

To complete the monitor activation, you must also include the smartagent/vsphere receiver item in a metrics pipeline. To do this, add the receiver item to the service > pipelines > metrics > receivers section of your configuration file.

See configuration examples for specific use cases that show how the Splunk OpenTelemetry Collector can integrate and complement existing environments.

The following is an example vsphere Smart Agent monitor configuration:

  - type: vsphere
    host: ""
    username: "administrator@vsphere.local"
    password: "S3cr3t"
    insecureSkipVerify: true

Configuration settings 🔗

The following table shows the configuration options for the vsphere monitor:

Option Required Type Description
host no string
port no integer (default: 0)
username no string This is the vSphere username.
password no string This is the vSphere password.
insecureSkipVerify no bool Indicate whether we verify the server's certificate chain and host name. (default: false)
inventoryRefreshInterval no integer Indicate how often to reload the inventory and inventory metrics. (default: 60s)
perfBatchSize no integer Indicate the maximum number of inventory objects to be queried for performance data per request. Set this value to 0 (zero) to request performance data for all inventory objects at a time. (default: 10)
tlsCACertPath no string This is the path to the CA certificate file.
tlsClientCertificatePath no string Use this to configure client certificates. Indicate the path to the client certificate. Both tlsClientKeyPath and tlsClientCertificatePath must be present. The files must contain PEM encoded data.
tlsClientKeyPath no string This is the path to the keyfile.

Metrics 🔗

The following metrics are available for this integration:
