PHPSW: Monitoring, May 2019
8 May 2019 at Runway East: Bristol

"Trust me, our customers will tell us that the system has an issue long before any monitoring can..." When Matt Wallace heard a senior developer say this nearly 10 years ago, he could hardly believe what he was hearing. Monitoring should *always* pick up issues quicker than your customers, and yet even in the age of NewRelic, DataDog, and Microsoft Insights there are a significant number of teams who only monitor whether their website is up or not. In this talk Matt takes us through the different layers of monitoring, explores the differences between the types and acronyms, and explains why, regardless of where you work in the stack, you should be monitoring first and writing code second.

We will take a look at some of the tools used for monitoring and issue diagnosis in a large scale PAAS hosting platform, and then take a look at how we can dig deeper to resolve performance issues using Blackfire.
