I've been fortunate enough to work for a company that develop performance monitoring so I always dogfood the latest cutting edge stuff that we do. Best part of the performance monitoring is that if the Request spans multiple Servers (load balancer/proxy, web-app, microservices, DB, etc), I can see it as a single transaction so that I can easily track down which Microservice that caused the performance slowness. For example, we have a web-app written in Python and a Microservice written in Java. A single request can end up at the Microservice level and our tool can see truly end-to-end => load balancer to web-app to microservice to database. On top of that, we also have an app that performs synthetic monitoring where I can set to automate certain User workflow and set it to run every 5 minutes. Combining both performance monitoring and synthetic monitoring give us a leg up on automating performance monitoring! Disclaimer: I work for AppNeta.
