It's basically a transmission that takes the shaft power from the engine and regulates that to a even output to run the electrical generator. That transmission has oil in it. There is a task to check the level of the oil. To check the level you over fill the IDG and then drain it down to the proper level. Not enough oil is bad, too much oil is bad.
So I'm sure power by the hour exists for IDG's but I would bet its rather expensive.

1. No. IDG’s fail on their own.
2. That is not how you check the oil level at all.
3. That is not how you service the oil level.
