Managing and Monitoring Docker
Docker is an open source software container management system. It provides a layer of abstraction and automation allowing multiple independent containers to run within a single Operating System. It is currently the de-facto standard for this type of technology.
The Instana agent will automatically detect the presence of Docker and install the sensor for it along with the sensor for the host OS. This level of automation reduces the effort required by the operations team to set up and maintain the monitoring. Rapidly start sending metric data with the minimum of work required.
Typical metrics that are tracked include:
- Block IO
See the documentation for a complete list.
Instana will track the metrics and health signatures of Docker with 1-second granularity and raise an Event within 3 seconds if they go out of bounds. The use of Machine Learning applied to pattern detection together with a curated knowledge base acting on the collected raw metrics, is what makes Instana different to other monitoring solutions. The intelligence is built in, there is no need to spend time creating and maintaining numerous health rules to trigger alerts.
Instana will detect configuration changes and tack them on the timeline. See how changes to configuration affect application performance.
