How do I activate the CIM server on ESXi 6.5 or later to monitor hardware information using WBEM?
Enabling the CIM module on VMware ESXi 6.5 or later
PRTG provides two technologies to monitor VMware host hardware, Simple Object Access Protocol (SOAP) and Web-Based Enterprise Management (WBEM). If you want to use the WBEM approach, you need to add the VMware Host Hardware (WBEM) sensor to your VMware ESXi server.
Monitoring via WBEM requires activated CIM interface
Accessing the target system and retrieving monitoring data via WBEM requires the Common Information Model (CIM) interface to be enabled on the ESXi host. On ESXi version 6.5 and later, CIM is disabled by default, so you must manually enable the module. You need CIM to add and use the VMware Host Hardware (WBEM) sensor.
