Bad Alternator?

My check engine light came on while driving. But didn't see any operational issues. So when I got home I hooked up ISTA and got a lot of electric related fault codes. (see picture). Name:  IMG_20180630_233618.jpg

I unlocked my cluster to check the voltage and found while the car is running I see 12.3 - 12.4 volts, which is low.

I replaced and registered my battery about a month ago because I was getting the increased discharged error. Which seemed to fix the error.

Seems like the alternator might be the issue but before I replaced it wanted to get others feedback.
