I'm running PRTG version 18.3.44.2059. I have upgraded my vCenter from version 6.5x to 7.0.0d and subsequently the majority of "esxservervmserver" sensors stopped working with error message "Input string was not in a correct format". The only sensors which are working correctly are: the sensor for vCenter VM itself and the sensors for VMs which are in Power off state. Also the "vmwaredatastoreexternsensor" and "esxserverhosthealthsensor" are working correctly. I have tried the Auto Discovery but it didn't solved the issue. Thanks for any advice
After the upgrade of vCenter the "esxservervmserver" sensors stopped working

Hello,
This issue might be related to a older bug that was present in the PRTG version that you are using. I would recommend that you update to the version 18.4.45.1898 or newer, since the issue is fixed since this version. For more information, I would suggest that you see our Release Notes.
