Finding a more common word for "mundanity"

As the title states, I'm looking for a word that emphasizes the mundane nature of something. "The ____ of my job had me bored and itching for something new."

My first thought was mundanity, but it doesn't seem to be very widely used - spell check doesn't even pick it up.

What is another, more common word for mundanity that is more widely understood to reflect the mundane nature of something?

Monotony:

Lack of variety and interest; tedious repetition and routine

Banality may be another good option.

something that is boring or ordinary; especially : an uninteresting statement : a banal remark

the quality of being ordinary or banal

Merriam-Webster Online

In this context I do prefer monotony, though.

Perhaps quotidian

Ordinary or everyday, especially when mundane: his story is an achingly human one, mired in quotidian details
