ElixirConf US 2018 – Simple is Beautiful: Building an SLA Monitoring Tool Using Elixir/OTP at PagerDuty – Aish Dahal

Starting in 2016, PagerDuty started replacing a lot of its in-house custom monitoring tools and SLA calculators with off the shelf software. However, for one critical piece of monitoring that involved 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 rather simpler and more reliable/scalable one all by using Elixir/OTP.
