VMware Host Performance (SOAP) Error




I need to add r VMware Host Performance (SOAP) to my ESXi 6.7.it returns the below error: Probe system have .net 4.0 and Vmware credentional is set in settings. Does this sensor suppor Esxi 6.7?

Could not create the sensor VMware Host Performance (SOAP) on device 172.X.X.X (Heather03) (172.X.X.X).

The underlying connection was closed: An unexpected error occurred on a send. Please check the following resources:

Requires .NET 4.0 or higher to be installed on the probe system. For this sensor type you must define credentials for VMware servers on the device you want to use the sensor on. Ensure you enter a user with sufficient access rights to obtain statistics (read-only usually works). The parent device must be a VMware ESXi server version 5.0, 5.1, 5.5, or 6.0. We recommend that you do not use this sensor type on your vCenter. Reliable hardware information can only be provided when this sensor is created on your physical host server as parent device. We recommend Windows 2012 R2 on the probe system for best performance of this sensor. Knowledge Base: I cannot add VMware sensors because of "wrong" password although it is correct. What can I do? This sensor type can have a high impact on the performance of your monitoring system. Please use it with care! We recommend that you use no more than 50 sensors of this sensor type on each probe.

Hello Sara,

Can you open the website https://esxi/mob/ in a webbrowser on the machine running the remote probe? Please do also check if the certificate matches the requirements by following this article.

Best regards, Felix

Hello Sara,

It is likely your root account has been locked out on the ESXi. Log with the DCUI and type the following command pam_tally2 --user root --reset
