In today’s “cloudy with a chance of outages" world, it is as important as ever to effectively monitor systems and their internals.

In this talk, Rob Desjarlais explores the tools that Liberty Mutual uses to monitor their systems, from vmstat, iostat, and ss (Socket State) to Datadog and more. These tools have helped Liberty Mutual understand how their systems and applications scale as their business grows to new heights.
