Docker Monitoring lives here.

12. • Comprehensive overview of CPU, physical memory,
network activity, disk I/O utilization and capacity
• Single dashboard to identify if problem areas are
server related or app related
• One solution for the entire team to share whether
focused on the application code, server capacity or
both
• New! Docker monitoring from the App’s perspective

13. Server Overview
See your servers from the App’s perspective
Quickly identify server
resource issues:

Network
Clickable - Monitor

15. Why do people care?
• How are containers different from VMs?

16. In the beginning…

20. But all was not well
• VMs are very resource heavy due to full machine virtualization
• VMs are still very much ‘puppies’
• VMs take a long time to start up and shut down
• VMs are not very portable

23. Docker Strengths
• Small and lightweight wrappers for your applications
• Pushes dependency management up the stack to developers
• Works with existing tooling (e.g. Chef, Puppet, Vagrant, Ansible)
• Leverages old, well-established technologies vetted by big names

24. What it means to whom:
Developers:
• Deployment is no longer a black box
• “It works on my machine”
• More architectural options
Ops:
• Easier portability and rollback
• Easier capacity planning
• Patches are easier
• More bang for your buck
Business:
• More Lamborghinis
• More maitais on the beach

25. What did we do for Docker?

26. What did we not do for Docker?

27. “App-centric” Docker monitoring
• Fix what was broken (i.e. make Docker feel first-class)
• Prioritize useful information over impressive information
• Don’t expect a PhD in sleuthing
• Optimize for now since later isn’t clear

28. What does Docker mean for APM?
