I have two server 2003 servers, one 32 bit and other 64
I am using nsc client 3.7 for both machines, disk i/o is not returning correct value in 64 bit os, also tried with nsc 3.8 and 3.9 no result

In 32 bit os everything is working fine for all nsc client version.

Please find attachment.

Unfortunately showing us your Host and service does not help much, you will need to show us your service configuration file so we can see what you have defined in it.

Hi, Sorry I forgot to upload the details.

Please go through below details.
define service {
use abc-generic-service
hostgroup_name abc_windows_servers
service_description C: Disk I/O rate
check_command check_counter!"\\PhysicalDisk(0 C:)\\Disk Bytes/sec"!Disk I/O rate C: %.2f byte/s!n!10485760!419430400
}

Is this the only perf counter used on the x64 machine? Are you using the x64 or x32 nsclient version on that server?
