CPU Utilization on Tru64

Hi, I'm running APPManager7 on Linux monitoring two Tru64 Unix servers, everything is fine BUT the CPU Utilization and Disk I/O Statistics graph are not working, I've read in FAQs and I did not find any information.... I checked the HostResource.xml and I see you used this commands:

"/usr/bin/vmstat 1 3" for CPU Utilization and "LANG=C iostat/d" for Disk I/O Statistics

I ran these commands as root in the console of both servers and I got the reports .......I don't know why these graphs are not working..

you can see it:

# /usr/bin/vmstat 1 3

PS: In ppmanager7 I used root user to log on my tru64 server
I'm not using SNMP

thanks in advance
