Performance Metrics for VMware Hardware Monitors

Monitor hardware sensors to view details on their status, count, and ESX host. The hardware sensors will be automatically discovered and added for monitoring once an ESX/ESXi host is added. 

By monitoring a hardware sensor, you can:

  • View the status and count of all the sensors in one view.
  • Add a threshold and availability profile to declare a specific resource as critical or down.
  • Analyze critical performance issues using reports.


Attribute Description
Hardware Sensor Status Split-up View the status of all the sensors monitored - Active, Down, Critical, Unknown
Sensor Detailed View Get a count of the total, active, down, and trouble sensors. 
ESX Details View details on your ESX host including its Bios version, number of CPU cores, CPU threads, UUID, hardware model, and more. 

Choose the Sensors for Monitoring:

Under Sensor Detailed View, click on a component, say Monitored, Active, or Down to navigate to the Individual Sensor View. Click on Modify Monitoring Sensors and select the desired hardware sensor that needs to be monitored. Click on Update.

Threshold Configuration

Once a hardware monitor is successfully added to your Site24x7 account, you can create a threshold and availability profile and configure conditions for different metrics. By doing this, the alarms engine can determine if the hardware sensor needs to be declared Critical, Trouble, or Down based on the breach of a set threshold condition. To add a threshold profile, 

  1. Log in to your Site24x7 account.
  2. Go to Admin > Configuration Profiles > Threshold and Availability > Add Threshold and Availability. You can also navigate via VMware > VMware Resources > ESX Hardware > click on a hardware monitor > hover on the hamburger icon beside the display name > Edit Hardware Monitor > Configuration Profiles > click on the pencil icon beside Threshold and Availability.
  3. Select the Monitor Type as VMware ESX Hardware from the drop-down list.
  4. Provide a Display Name for identification purposes.
  5. Provide threshold values and be notified as Trouble, Critical, or Down when a SystemBoard sensor, cable sensor, bios sensor, voltage sensor or any other sensor is Down, Trouble, or in an Unknown status. 
  6. Save your changes.

When there is a threshold breach, an alert will be immediately triggered and monitor will be turned to Down, Trouble, or Critical state based on your configuration.
