Talk 2 - Philipp Krenn - Monitor Your Distributed Java Applications with the Elastic Stack

"With microservices, every outage is like a murder mystery" is a common complaint. But it doesn't have to be!

This talk gives an overview on how to monitor Spring Boot applications, since they are increasingly popular for building microservices.

Philipp dive into: * System metrics: Keep track of network traffic and system load. * Application logs: Collect and parse your logs. * Uptime monitoring: Use Heartbeat to ping services and actively monitor their availability. * Application metrics: Get the information from Boot's metric and health endpoints via REST and JMX. * Request tracing: Trace requests through a distributed system and to show how long each call takes and where errors are happening.

And he will do all of that live, since it is so easy and much more interactive that way.

About Philipp

Philipp is part of the infrastructure team and a developer advocate at Elastic. He is frequently talking about full-text search, databases, operations, and security. Additionally, he is organizing multiple meetups in Vienna.
