I've got a cacti installation running under Windows Server 2003 on IIS.
That installation used to work for a long time, but suddenly the system started to have gaps in the graphs for partition usage and processor information. These were about few hours to multiple day. It usually started to work again after a reboot or patient waiting.
To make this clear: I didn't change anything, neither on the querried machines nor on the cacti server in between these working/not_working-periods.
But some months ago it didn't recover and I now can't get any partition information from my windows machines. There are no linux machines with snmp enabled.
What always works and never stopped to do so are the network graphs.
I've tried most of the debugging steps mentioned on the cacti site, but haven't been successfull so far.
Filemon doesn't show any denied errors, so I guess the permission settings are correct.
I've just installed the spine addon, but that didn't change the situation.
Here's a debug output of one of the "mounted partition"-data query update:
Code: Select all

+ Found type = '6 '[script query].

But, and that's most confusing in my opinion:
If I use a program like WSPingProPack to query the same snmp information (run from the cacti web server system) to query the same machines, I'm getting perfectly plausible values.

. What query did you run? Try running the queries manually you see cacti executing -- either from the cacti.log or the poller cache.
