1 / 1 point

It is derived by scraping social media for complaints

It closely tracks well-known system behavior

It shows long-term trends clearly

Correct

Correct! A smoothed-out signal over a long time horizon is more valuable for an SLI, because these metrics tend to have lower variance and higher signal-to-noise ratio.

It reacts quickly to changes and outages

It is a close approximation of the user experience

Correct

That's right! We want to measure the user experience as directly as possible. We assume that when that experience is poor enough, we are not meeting our users' expectations of service reliability and they are therefore unhappy with our service.
