Agent Check Agent Check
vsphere graph


This check collects resource usage metrics from your vSphere cluster—CPU, disk, memory, and network usage. It also watches your vCenter server for events and emits them to Datadog.



The vSphere check is packaged with the Agent, so simply install the Agent on your vCenter server.


In the Administration section of vCenter, add a read-only user called datadog-readonly.

Then, create a file vsphere.yaml in the Datadog Agent’s conf.d directory. See the sample vsphere.yaml for all available configuration options:


  - name: main-vcenter # how metrics will be tagged, i.e. 'vcenter_server:main-vcenter'
    host: <VCENTER_HOSTNAME>          # e.g. myvcenter.example.com
    username: <USER_YOU_JUST_CREATED> # e.g. datadog-readonly@vsphere.local
    password: <PASSWORD>

Restart the Agent to start sending vSphere metrics and events to Datadog.

Configuration Options

  • ssl_verify (Optional) - Set to false to disable SSL verification, when connecting to vCenter
  • ssl_capath (Optional) - Set to the absolute file path of a directory containing CA certificates in PEM format
  • host_include_only_regex (Optional) - Use a regex like this if you want only the check to fetch metrics for these ESXi hosts and the VMs running on it
  • vm_include_only_regex (Optional) - Use a regex to include only the VMs that are matching this pattern.
  • include_only_marked (Optional) - Set to true if you’d like to only collect metrics on vSphere VMs which are marked by a custom field with the value ‘DatadogMonitored’. To set this custom field with PowerCLI, use the follow command: Get-VM <MyVMName> | Set-CustomField -Name "DatadogMonitored" -Value "DatadogMonitored"
  • all_metrics (Optional) - When set to true, this will collect EVERY metric from vCenter, which means a LOT of metrics you probably do not care about. We have selected a set of metrics that are interesting to monitor for you if false.
  • event_config (Optional) - Event config is a dictionary. For now the only switch you can flip is collect_vcenter_alarms which will send as events the alarms set in vCenter.


Run the Agent’s status subcommand and look for vsphere under the Checks section:


      - instance #0 [OK]
      - Collected 26 metrics, 0 events & 1 service check



The vsphere check is compatible with all Windows platforms.

This check watches vCenter’s Event Manager for events and emits them to Datadog. It does NOT emit the following event types:

  • AlarmStatusChangedEvent:Gray
  • VmBeingHotMigratedEvent
  • VmResumedEvent
  • VmReconfiguredEvent
  • VmPoweredOnEvent
  • VmMigratedEvent
  • TaskEvent:Initialize powering On
  • TaskEvent:Power Off virtual machine
  • TaskEvent:Power On virtual machine
  • TaskEvent:Reconfigure virtual machine
  • TaskEvent:Relocate virtual machine
  • TaskEvent:Suspend virtual machine
  • TaskEvent:Migrate virtual machine
  • VmMessageEvent
  • VmSuspendedEvent
  • VmPoweredOffEvent

Service Checks


Returns CRITICAL if the Agent cannot connect to vCenter to collect metrics, otherwise OK.
