Introduction to the SLA in relation to SLI and SLO

Everyone experiences stress at work—thankfully, it’s a topic folks aren’t shying away from anymore.

But for on-call engineers, alert fatigue is a phenomenon closer to home. Unfortunately, like stress, it can be just as insidious and drastically impact those it affects.

First discussed in the context of hospital settings, this phrase later entered engineering circles. Alert fatigue is when an excessive number of alerts overwhelms the individuals responsible for answering them, often over a prolonged period, resulting in missed or delayed responses, or them being ignored altogether

The impact of this fatigue can have an effect beyond the individual and can create significant risks for your organization.

But, if you approach on-call the right way, you can mitigate the impacts of alert fatigue or, better yet, avoid it altogether. Here, we'll dive into the tactics teams can implement to address alert fatigue and its underlying causes.

While working on SLOs, SLAs and SLIs I have found that there are only so many ways to aggregate service metrics. I have not yet found somewhere that attempts to review the different aggregation methods and what their relative strengths and weaknesses are.
