Creating an Alert Help

So there is a format function to convert raw bps to a more friendly display, but for some reason it doesn't show up in the gui for all the interfaces variables where you would want it. It does work if you just manually set the format though. The way I always worked around it was to hit the insert variable button and find interface bandwidth, check the box and you'll get an option that says something to the effect of format output with a list of conversions it will do. Pick the bandwidth one and it concats a bit into the end of the variable, I think it's like ;f=bandwidth or similar. In any case once you see the syntax to use you can just copy it into your bps variables and the alerts will convert the units from bps to m/g or whatever is appropriate.
