Perfcounter on Windows Agent returning zero

[johanpre44]

I want to monitor disk IO, so I added the following lines to the W32 Agent config file:
PerfCounter=Disk-ReadBytes-per-sec,"\PhysicalDisk(_Total)\Disk Read Bytes/sec",60
PerfCounter=Disk-WriteBytes-per-sec,"\PhysicalDisk(_Total)\Disk Write Bytes/sec",60
PerfCounter=Disk-splitio-per-sec,"\PhysicalDisk(_Total)\Split IO/sec",60

I then create the Items in Zabbix with the keys:
perf_counter[\PhysicalDisk(_Total)\Disk Read Bytes/sec]
perf_counter[\PhysicalDisk(_Total)\Disk Write Bytes/sec]
perf_counter[\PhysicalDisk(_Total)\Split IO/sec]

I used a store value of "delta (speed per second)" and a 30 second update interval

Rest of the Item configuration is default

Zabbix seems to read these Items, but it returns nothing, but when I fire up the performance monitor on the windows host I can actualy see some activity

Is the problem with the COnfiguration of the W32 Agent or with the Zabbix Server. Please Help.

I see the same problem on some of my W2K servers
Zabbix server and Agent version are 1.1.4

I tried several syntax, and I always get 0.0000 as result !!!
No errors reported in the log file even in debug mode ...

What's wrong

PS: on some of my servers it is working OK for one counter not for all
and on other one all are working fine !!!

Make sure that multiplier is not set to 0 for the item.

I run on the W2K server the command
ZabbixagentW32.exe test DiskRead60

and I got
Configuration file OK
DiskWrite60 [0.000000]

Definition of DiskRead60

PerfCounter=DiskRead60, "\\VMPAR1\Disque physique(_Total)\Lectures disque, octets/s",60

I can't see what is wrong

I try to downgrade to 1.1.3 agent with the same result ............
