Image Credit: PagerDutyPagerDuty, a popular tool among developers and system administrators, stands to get more helpful and less of an annoyance, thanks to $27.2 million in new funding. Sysadmins and others use PagerDuty to stay on top of alerts from several monitoring tools. Getting those kinds of alerts is often critical (your website is down!) but if they’re not well-managed, these alerts can lead to stress, confusion, and premature hair loss.
