How to Integrate other vendor's CPU polling with Top 10 average CPU Load

Hi,

I have to monitoring of CPU Utilization and Memory Used of variety of vendor: HP, 3COM, Check Point, Blue Coat, Cisco, Alcatel, Fortigate. I was successful to polling them out of my Orion Web Console. But how to put them together in Top xx Node average CPU load, % Memory Used v...v.. Now only Cisco device in that Top xx resouce

And the second question is Do the UnDPs create some custom variable to those polling vendor like ${CpuLoad} and ${MemoryUsed}?

I really need an answer for this.

Please guide me if anyone has solutions.
