Hi JamesFirth

Try restart wmi services "net stop winmgmt" (and all depending services).

btw: Why not use SNMP? its faster and lesser resources are used.

Hi Thomas,

that didnt fix it, use wmi for all sesnors, and are trialing the snmp sensors on a few devices to see if there any differences

Dear James

Which sensor exactly are you using? What happens if you create the sensor anew, does the new sensor recognize the actual capacity?

Hi James

Just an odd question (but I need to ask), After you increased the virtual HD, did you extend the Harddrive in Windows as well AND what happens when you recreate the WMI Sensor, does it show you the correct HD size?

Hi,

i did extend the drive in windows, and i have not recreated a sesnor, i am using the WMI Multidisk sensor, i dont believe that i should have to re-create the sensor, as we need historical data of when the drive changed and capacity. i will add another disk sensor to see if it picks up the changes.

hmm..thats odd. I understand why you don't want to use a new WMI or use snmp. (1 sensor for multiple harddrives is quite handy) I tried with a wmi multidrive sensor and the freespace immediately changed, after I extended a disk with additional 5GB on a Windows 2008 R2.

I use the latest version. Let's wait what happens when you create a new sensor, if the new one still shows the old size.

hi, i created a sensor and it didn't pick up the change, i always have a single disk sensor for monitoring this drive also.

the reason why we dont use snmp is most sites block this via their firewalls

Hi James,

Please use the WMI Tester and perform a Logical Disk scan below the Advanced Tab. Does the returned value match with the value in PRTG?

Best regards, Felix
