Why not use 'Options[]: perminute' (without the gauge option) to get total DHCP requests per minute? If this is too small, the use 'Factor[]: 5' to get the per-5min total (youd need to relabel your axis of course). You'd also need to be using RRDTool as the numbers would be decimals - and youd also need 'Options[]: integer' to make it round off to an integer. For this sort of thing, here we use perminute and graph the average requests/min or perhour if this is too small. Alternatively, if you are more interested in total requests per day/week/month then use the routers2 frontend, it will calculate these for you. > Would it only be possible to do this with an external script?

I've never use WMI, only PerfMon (via the pNSclient agent) and it works fast enough.
