What to Look for in Docker Monitoring Tools
The importance of Docker is constantly rising as the utilization of container technology continues to grow across multiple industries. Docker containers have become essential for IT teams who want to ensure the functionality of a software when it is moved from one environment to another. The process from development to production becomes simple with Docker, but it is vital to have robust Docker monitoring enabling you to quickly fix any issues related to application performance.
Monitoring containerized environments isn’t always the easiest task, so here are a few key capabilities to look for in Docker monitoring tools that will add value toward your containerization efforts.
Drill down metrics and service checks
It is important to be able to monitor different segments of Docker (i.e. hosts, microservice applications, etc.) via a single pane of glass. By drilling down to the host level to view infrastructure data, you can pull vital information from all your containers and monitor resource usage metrics such as CPU, size and memory. This gives users the ability to monitor Docker on a per container basis and compare the performance of an individual host to the greater environment. By having several service checks and performance metrics that drill down to specific containers, you can evaluate how applications are being impacted at a service level.
Dashboards that show Docker’s health
Insightful dashboards are a crucial aspect of any monitoring solution, and they are especially important when it comes to Docker. Dashboards with clear visualization give you an instant status report of your Docker environment and its overall health. Be sure you can easily access statistics such as number of containers running, total number stopped and total number of containers running on the specified Docker host. Having this capability will save you time and ensure that Docker is running as expected. If you are monitoring applications operating inside your Docker containers, it becomes even more important that your monitoring tool provides accurate visibility across the entire infrastructure.
Flexibility and scalability
Two of the biggest issues organizations face when moving to a containerized infrastructure are the maturity in its technology and worries surrounding orchestration. The post-implementation phase of Docker usually rids these concerns, but it doesn’t change the fact that containers are often grouped in large quantities and move at a rapid pace.
A Docker monitoring tool needs to empower you at a managerial level, meaning it can keep up with the needs of the business in terms of flexibility and scalability. With a monitoring solution that can quickly adapt to growth and changes in your environment, Docker will be able to do its job more effectively and build, ship, and run distributed applications as necessary.
Demonstrate return on investment
While Docker has presented great value to countless organizations, there is always a need to showcase the value/ROI of platforms that require a significant amount of resources and investment. A monitoring tool should be able to show how Docker has improved performance, increased uptime, and achieved application portability across multiple environments. The amazing capabilities of Docker may be evident when reading tech headlines, but what matters more than the industry success rate is effectively implementing Docker into your own infrastructure, and monitoring it so there is full assurance that you are making the most of your containerization efforts.
