is it normal to request index for every new article in Google Webmaster Tools?

I have uploaded around 30 articles(1 per day) on my WordPress blogs and Google has so far indexed around 12 of them. I can only see my rankings for the keywords of those 12 articles inside ahref/semrush.

Should I Request Index(fetch as Google) in Google Webmaster Tools for every new article which I post so that I start seeing the rankings for my new articles too or would it be considered Black-hat/Spamming?

No. This is definitely not normal. There are other ways to encourage indexing. Are you Tweeting your articles out when you post them?
