1.3.6.1.4.1.123456.1 means total number of the value.

     1.3.6.1.4.1.123456.2 is the current value.

I wannor create a monitor to get the value like this: (1.3.6.1.4.1.123456.2 * 100 / 1.3.6.1.4.1.123456.1)

Or I can create two monitors to get values of those two oids separately. 

and then, how to set the config file to show the value (1.3.6.1.4.1.123456.2 * 100 / 1.3.6.1.4.1.123456.1) in the snapshot dial.
