Daily Checklist: Sensor Warnings when Monitoring ESX Host Server Hardware Occasionally, sensors in PRTG show a warning status with the message “X elements not found” (or with another number) when monitoring ESX host server hardware. Though, the sensor worked correctly previously. This issue might appear when monitoring with the VMware Host Hardware Status sensor via SOAP, as well as it can be the case when monitoring the server via WBEM or SNMP.
