Interface Alert : threshold of high utilization exceeded : current value

Hi everyone,

Just want to know how can I configure the high utilization alert on cisco interface to show the current value using Mbps instead of raw data?

Current showing:

threshold of high utilization exceeded: current value 1001677.690000

Can this be changed to:
threshold of high utilization exceeded: current value 7.64 Mbps

I know this may be done by using transform, however I did not know how to write the transform script, I tried to find out how to write those script from internet but still no idea.

Grateful if someone can help me to figure out how can I achieve this.

Thanks a lot.
