4. Who has used Prometheus?

5. https://jackiechen.org/2015/05/19/understanding-kubernetes/

6. Questions we got asked

7. It is so new, what do I even monitor?

8. How do I monitor my apps?
Just expose /metrics !

9. What if I can’t/don’t want to expose /metrics? Push!

10. Can we just use Nagios?

12. Seniors sysadmins had hard questions:
Uptime
Data persistence
Scalability

13. Culture change through Prometheus

14. Devs own the metrics

15. Devs can spin up a prometheus for themselves

16. BUT

18. What would I do differently?
Start with grafana
Show how HA works
Share the success stories
Help devs with exporters a lot more

19. There are now so many resources available
Many more success stories.
Much bigger community
Talked about at conferences and even has its own PromCon
Even more learning resources
Excellent dashboards available out of the box
