In our October online meetup we asked three of our engineers to demonstrate their favorite monitoring tools for containers, and demonstrate how to deploy and utilize them. They provided an in-depth overview of Sysdig, Datadog and Prometheus and try to help you determine which tool is best for your workload, and demonstrated: - Deploying container monitoring tools from the Rancher catalog. - Key differences between container and server monitoring. - How Sysdig, Datadog and Prometheus compare with one another. Please register for the next Rancher online meetup: http://rancher.com/meetup

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

Monitoring in the catalog

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.
