Power State Monitors
The power state monitors help you manage both available computing resources within your clusters, resource pools, and other logical divisions in your vSphere-managed infrastructure, as well as power consumption in your physical datacenters. Power state changes to your hosts, and the VMs running on them, can be alerted and acted on.
The power state monitors can answer questions such as the following:
- Has a mission-critical VM powered off?
- Did a routine maintenance procedure start and complete properly?
- Are enough expected VMs powering down during the weekend, indicating vSphere’s Distributed Power Management is functioning correctly?
ESX Server Power State
(VMware only)The ESX Server Power State monitor watches for changes to the power states of an ESX server that is managed by VMware vSphere, and can run alert or action profiles based on the change.
ESX Server Power State Monitor Status Types
In Uptime Infrastructure Monitor, vSphere hosts will be in one of the following states:
Powered On | The host is running. | |
Powered Off | The host was powered off by an administrator through the vSphere Client. | |
Put on Standby | The host was put in standby mode either explicitly by an administrator, or automatically by vSphere Distributed Power Management (DPM). | |
Put in Maintenance | The host state is determined to be “unknown” if it is disconnected or not responding, implying it is in maintenance. | |
Configuring ESX Server Power State Monitors
To configure an ESX Server Power State monitor, do the following:
- On the Infrastructure tree, click Add Service Monitor.
- In the VM Monitors section, click the name of the monitor you want to configure, and then click Continue.
- Complete the monitor information fields.
See Monitor Identification for more information on configuring service monitor information fields.
For more information on these power states, see ESX Server Power State Monitor Status Types.

When selecting an Element associated with this service monitor, only ESX servers monitored in Uptime Infrastructure Monitor via vSync will appear in the Single System list. |
In the main ESX Server Power State Settings section, in the Powered On sub-section, do the following:
- In the Set Status to drop-down box, indicate what the monitor’s Uptime Infrastructure Monitor state will be when the ESX server’s state is Powered On.
- From the list, select which (if any) Alert Profiles are triggered when the host enters a powered-on state.
- From the list select which (if any) Action Profiles will be triggered when the host enters a powered-on state.
In the Powered Off sub-section, do the following:
- In the Set Status to drop-down box, indicate what the monitor’s Uptime Infrastructure Monitor state will be when the ESX server’s state is Powered Off.
- From the list, select which (if any) Alert Profiles are triggered when the host enters a powered-off state.
- From the list select which (if any) Action Profiles will be triggered when the host enters a powered-off state.
In the Put on Standby sub-section, do the following:
- In the Set Status to drop-down box, indicate what the monitor’s Uptime Infrastructure Monitor state will be when the ESX server’s state is Standby.
- From the list, select which (if any) Alert Profiles are triggered when the host enters a standby state.
- From the list select which (if any) Action Profiles will be triggered when the host enters a standby state.
In the Put in Maintenance sub-section, do the following:
- In the Set Status to drop-down box, indicate what the monitor’s Uptime Infrastructure Monitor state will be when the ESX server’s state is Unknown.
- From the list, select which (if any) Alert Profiles are triggered when the host enters an unknown state.
- From the list select which (if any) Action Profiles will be triggered when the host enters an unknown state.
Complete the following settings:
- Timing Settings (see Adding Monitor Timing Settings Information for more information)
- Monitoring Period settings (see Monitor Timing Settings for more information)
Click Finish.
VM Instance Power State (VMware only)
The VM Instance Power State monitor watches for changes to the power states of a VM running on an ESX server that is managed by vSphere, and can run alert or action profiles based on the change.
See Power State Monitors for more information.
VM Instance Power State Monitor Status Types
A virtual machine’s three basic power states are as follows:
Powered On | The VM instance is running. | |
Powered Off | The VM instance is not running. | |
Suspended | The VM instance is not running, but a snapshot of its running applications and processes is retained. | |
Configuring VM Instance Power State Monitors
To configure a VM Instance Power State monitor, do the following:
- On the Infrastructure tree, click Add Service Monitor.
- In the VM Monitors section, click the name of the monitor you want to configure, and then click Continue.
- Complete the monitor information fields.
See Monitor Identification for more information on configuring service monitor information fields.
For more information on these VM power states, see VM Instance Power State Monitor Status Types.

When selecting a VM associated with this service monitor, only VMs monitored in Uptime Infrastructure Monitor via vSync will appear in the Single System list. |
In the main VM Instance Power State Settings section, in the Powered On sub-section, do the following:
- In the Set Status to drop-down box, indicate what the monitor’s Uptime Infrastructure Monitor state will be when the VM’s state is “powered on”.
- From the list, select which (if any) Alert Profiles are triggered when the host enters a powered-on state.
- From the list select which (if any) Action Profiles will be triggered when the host enters a powered-on state.
In the Powered Off sub-section, do the following:
- In the Set Status to drop-down box, indicate what the monitor’s Uptime Infrastructure Monitor state will be when the VM’s state is “powered off”.
- From the list, select which (if any) Alert Profiles are triggered when the host enters a powered-off state.
- From the list select which (if any) Action Profiles will be triggered when the host enters a powered-off state.
In the Suspended sub-section, do the following:
- In the Set Status to drop-down box, indicate what the monitor’s Uptime Infrastructure Monitor state will be when the VM’s state is “suspended”.
- From the list, select which (if any) Alert Profiles are triggered when the host enters a suspended state.
- From the list select which (if any) Action Profiles will be triggered when the host enters a suspended state.
Complete the following settings:
- Timing Settings (see Adding Monitor Timing Settings Information for more information)
- Monitoring Period settings (see Monitor Timing Settings for more information)
