Ask HN: How important are real time analytics?

Hi

I am working on a very rudimentary analytics tool for a couple of projects.

I only capture page views, unique visitors (a hash), referrals, timeOnSite, agent info, load time for each page and every hour I aggregate the result and store them on a CDN. I also have some alerts that are triggered and sent immediately.

This leads to a cost effective and simple solution... but I am totally missing the real-time statistics, so far I am ok with this, I only review the results once or twice a day or when an alert is triggered.

But I was wondering if there is something important that I am missing without the real time information? Why is the real time information useful for you? How much do you spend reviewing the real time analytics?

Thank you.
