Dabbler : used Docker during a given month, but hadn’t reached significant use as defined by Adopter. Adopter : the average number of containers running during the month was at least 50% the number of distinct hosts run, or there were at least as many distinct containers as distinct hosts run during the month. Docker Adoption

CONTAINERS INCREASE COMPLEXITY HOW DO WE MONITOR THEM?

Side Car Containers
AS COMPLEXITY INCREASES FUNDAMENTALS BECOME MORE IMPORTANT
4 QUALITIES OF GOOD METRICS NOT ALL METRICS ARE EQUAL
- MUST BE WELL UNDERSTOOD
- SUFFICIENT GRANULARITY
1 second Peak 46% 1 minute Peak 36% 5 minutes Peak 12%
- TAGGED & FILTERABLE
Query Based Monitoring “What’s the average throughput of application:nginx per version ?” “Alert me when role:web-app running
application:postgres
hosted in region:eu-west-1
behaves differently than region:eu-west-2 ”

SUMMARY 1. Both Docker adoption and system complexity continue to grow 2. The fundamentals of monitoring are therefore more important than ever
MERCI ! DANIEL MAHER @phrawzty daniel.maher@datadoghq.com
At Datadog we help thousands of organisations monitor their infrastructure and applications. In this session, we’ll dive deeper into the several hundred trillion data points we’ve gathered to extract information about the real-world use of containers and explore trends in container use. Furthermore, we’ll discuss the top applications being used in containers and, using the data, provide insight into what and how to monitor and understand this brave new containerised world!
