Monitor Type: vsphere (Source)

Accepts Endpoints: Yes

Multiple Instances Allowed: Yes

Overview 🔗

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 into 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 config, 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.

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

Sample YAML configuration:

monitors:
  - type: vsphere
    host: "172.16.248.140"
    username: "administrator@vsphere.local"
    password: "S3cr3t"

    Storage DRS virtual disk metric for the read workload model.
  • vsphere.virtual_disk_read_oio (gauge)
    Average number of outstanding read requests to the virtual disk during the collection interval.
  • vsphere.virtual_disk_small_seeks (gauge)
    Number of seeks during the interval that were less than 64 LBNs apart.
  • vsphere.virtual_disk_total_read_latency_ms (gauge)
    Average amount of time for a read operation from the virtual disk. Total latency = kernel latency + device latency.
  • vsphere.virtual_disk_total_write_latency_ms (gauge)
    The average time a write to the virtual disk takes.
  • vsphere.virtual_disk_write_iosize (gauge)
    Average write request size in bytes.
  • vsphere.virtual_disk_write_kbs (gauge)
    Rate of writing data to the virtual disk.
  • vsphere.virtual_disk_write_latency_us (gauge)
    Write latency in microseconds.
  • vsphere.virtual_disk_write_load_metric (gauge)
    Storage DRS virtual disk metric for the write workload model.
  • vsphere.virtual_disk_write_oio (gauge)
    Average number of outstanding write requests to the virtual disk during the collection interval.

Non-default metrics (version 4.7.0+) 🔗

To emit metrics that are not default, you can add those metrics in the generic monitor-level extraMetrics config option. Metrics that are derived from specific configuration options that do not appear in the above list of metrics do not need to be added to extraMetrics.

To see a list of metrics that will be emitted you can run agent-status monitors after configuring this monitor in a running agent instance.

Dimensions 🔗

The following dimensions may occur on metrics emitted by this monitor. Some dimensions may be specific to certain metrics.

Name Description
cluster If the metric's host or virtual machine is attached to a cluster, the name of the cluster.
datacenter The name of the datacenter to which the metric pertains.
esx_ip The IP address of the ESX host to which the metric pertains.
guest_family For virtual machine metrics, the guest operating system family for the virtual machine to which this metric pertains. For example 'linuxGuest'.
guest_fullname For virtual machine metrics, the full name of the guest operating system for the virtual machine to which the metric pertains. For example 'Windows 2000 Professional'.
guest_id For virtual machine metrics, the guest identifier of the virtual machine to which the metric pertains.
object For some metrics, the source of the metric. For example, the identifier of a NIC for a network metric, or the processor number for a CPU metric.
object_type The type of the resource to which the metric pertains. Values can be 'VirtualMachine' for a VM, or 'HostSystem' for an ESX host.
ref_id The unique vCenter identifier for the resource to which the metric pertains.
vcenter The hostname of the vCenter server to which the monitor is connected.
vm_ip For virtual machine metrics, the IP address of the virtual machine to which this metric pertains.
vm_name For virtual machine metrics, the name of the virtual machine to which the metric pertains.
