Monitoring and Alerting: Knowing the Unknown

Successful monitoring and alerting systems can detect all known points of failure and include alerts that will quickly escalate these problems to the appropriate parties.

The meat of this talk will focus on addressing the problems in a system that have not been thought of specifically. What about the monsters lurking in the dark to strike when your team is out? How do you find those unknown unknowns and give your future self the tools to investigate them? We will look at the best tactics and technologies for finding those unforeseen problems and bringing them to light.

First, I will discuss methods for discovering the most common points of failure–ideally before a product or feature goes live. Next I will briefly go over best practices for logging in a system. Next, we will discuss methods for detecting problems when all other techniques have failed. Finally I will do an overview of open source logging/alerting systems like Elasticsearch, Logstash, and Kibana (ELK) by Elastic.

By the end of this talk attendees should: Understand the key components of a thorough monitoring/alerting system Gain some new techniques for catching and debugging the more elusive issues Have some familiarity with open source logging/alerting technologies
