Windows 2012 with iscsi volume doesn't appear in Cacti

[Moartn82]

Hi there.

We use CactiEZ (Version 0.8.8a )
Everything works fine, but I've got a little problem.
I add a Windows 2012 server into Cacti and everything looks fine.
But I miss one disk in Cacti (V:\). This is a iSCSI volume, connected to a QNAP.
When I verbose the query Get Mounted Partition, I get this:

I see that the Index is correct:
Index 1 is C:
Index 2 is D:
Index 3 is V:
Index 4 is Physical mem
Index 5 is Virtual Mem

But when Cacti executing script query, index 3 doesn't work.

When I do a SNMP walk on the Windows 2012 server, I get:

iso.3.6.1.2.1.25.2.3.1.7.5 = Counter32: 0

So I think the problem is that I get a - result on oid .3 (iso.3.6.1.2.1.25.2.3.1.5.3 = INTEGER: -1687978753)
The disk is +/- 10 TB big.

Can anybody help me?

Thanks in advance.

You're issue is with SNMP not being able to handle the large intenger numbers required for the 10 TB disk. You may want to check out the WMI stuff available her in the forum to monitor disk spaces via WMI.

two problems.
1) ss_host_disk.php isnt even displaying Index 3 in the output.
2) Windows still using 32bit counters which are not large enough and thus, display negative results.

Googling one finds this has been a long standing problem http://forums.cacti.net/viewtopic.php?f=21&t=28713 which in theory was resolved in 0.8.7g per http://bugs.cacti.net/view.php?id=1292. Looks like only the GET command takes into account the negative values, not the QUERY commands.

can you validate by manually running the ss_poller and ss_host_disk script the get command functions properly with index 3?

Once thats done, would be worthwhile creating another bug so the QUERY command also is fixed. make sure to reference either this or the original threads in the bug.

I hope this is the informatie you need?

My large disk seems to work:
