Simple is beautiful: building an SLA monitoring tool at PagerDuty

Starting in 2016, PagerDuty started replacing a lot of its in-house custom monitoring tools and SLA calculators with off-the-shelf software. However, one critical piece of monitoring involving detailed business logic could not be replaced with anything off-the-shelf. As a result, PagerDuty built its own highly available Elixir powered monitoring tool that used Kafka not only as a communication layer but also as a storage layer. This talk is a story of how PagerDuty replaced a complex in-house monitoring tool with a simpler and more reliable/scalable one all by using Elixir/OTP.

OBJECTIVES

This talk demonstrates how the message based paradigm championed by Erlang and adopted in Elixir helped address PagerDuty's scalibility woes, all while keeping the codebase minimal and maintainable.
