Who actually uses these products,
and what made them stay.

The PagerDuty On-Call Engineer

A software engineer or site reliability engineer who is on a rotating on-call schedule and whose relationship with PagerDuty is defined by the moments it wakes them up. They've been paged at 3am. They've resolved incidents from their phone in bed. They've also been paged for something that wasn't an incident — a flaky alert, a threshold set too low, a monitoring rule that was never updated after the system changed. Every false positive erodes their trust in the alert and their willingness to respond with full urgency next time. They manage this tension carefully.

The Datadog SRE

A site reliability engineer or DevOps engineer responsible for the uptime and performance of production systems. They chose Datadog because it combines metrics, traces, logs, and alerts in one place — but now they're paying for all of it and the bill is terrifying. They've built dashboards that are beautiful, alerts that are precise, and runbooks that nobody reads. They are the person who gets paged at 3 AM and needs to determine in 90 seconds whether this is a real incident or a flapping alert.
