Windows is probably not reporting the drive properly. Alerts don't affect polling or graphing at all.
 
You should run the poller module with -d to see what the system is returning :
 
./poller.php -h <host> -m storage -d

Nobody has a clue why Im having this problem? Screenshot attached showing that the C drive is not picking up. 

Need help on this please. I've tried removing the server and re-adding it.

Hello,

I want to monitor windows servers for C drive space. While I had a policy that was using the storage_perc gt 90 and it was working fine, I want to monitor instead just for servers with 5 GB of space or less, on any drive for now, then narrow it to certain drives.

I put storage_free lt 5 (thinking this would look for 5GB or less, maybe its 5% or less not sure) but it's throwing some alerts that are not true.

I get some servers with the art and when I check it shows as if the C drive had 0 B left, but in reality they have 11 GB and more free.

Any idea how I can accomplish what I want?

Thanks,

Darian
