Comparing Container Monitoring 1) Ease of deployment 2) Level of detail of information presented 3) Level of aggregation of information from entire deployment 4) Ability to raise alerts from the data 5) Ability to monitor non-Docker resources 6) Cost 12 http://rancher.com/comparing-monitoring-options-for- docker-deployments/

15. Monitor containers with Datadog

16. What is Datadog? Datadog is a monitoring service for dynamic cloud infrastructure and large-scale applications Signup for a free trial: https://www.datadoghq.com/datadog-signup/

17. Deploying the agent Traditional Installation Datadog agent runs next to the Docker engine Docker-ized Datadog Agent Agent is deployed in a container The Agent is responsible for sending native host and container-specific metrics, like number of containers, load, memory, disk usage, and latency. For more information: http://docs.datadoghq.com/integrations/docker/

18. Service discovery - Useful when using container orchestration tools like Kubernetes or ECS - Allows users to continuously monitor Dockerized applications without interruption as they move across containers and hosts How it works: 1. You define configuration templates for images you want to monitor 2. The Datadog Agent listens to Docker events and spots when containers are created, destroyed, started or stopped 3. The Agent loads the configuration template for the corresponding image, and automatically re-set up its checks For more information: http://docs.datadoghq.com/guides/servicediscovery/ Custom Metrics - Use the Datadog Agent with DogStatsD for sending in custom metrics instrumented in containerized applications - DogstatsD is the Datadog extension of StatsD, which adds metric tagging. For more information: http://docs.datadoghq.com/guides/dogstatsd/
