Performance data via HPOV tool

Hi,
We have HP OpenView tool to extract utilization report and extract them in csv. Every month I pull 30 days CPU and Memory utilization, every 5 minutes via GUI and export it in csv (excel) format. It is always a time consuming process to run it on a set of servers and then pick next set because we have 1000+ servers.
If anybody is using it, can we know some command to run on HP OpenView Server to extract data, instead of GUI ? May be I will be able to select more number of servers if I run it in command line. It will make my job easier.
Regards
