![]() You must also be able to identify the origin of every log, and attach relevant metadata such as the container’s name and ID. Monitoring application logs requires individually parsing and combining them. Docker containers collect and forward logs to their destination using a logging driver.Įach container running in the cluster may be running multiple processes, with each process using a different stderr and stdout log stream. Log Management in ContainersĬontainer logs differ from traditional application logs, as they are defined as stderr and stdout console output streams. If, for example, there is a memory failure in a container, monitoring the overall performance of a server might not reveal the slowness of the container. In such instances, the cluster host doesn’t necessarily use all the resources, so regular resource allocation monitoring is insufficient. This is important because if one container fully utilizes the resources, it will result in the underperformance of other containers competing for the same resources. You can set limits to the compute resources a container can use. As containers are isolated, this makes the monitoring and troubleshooting process easier. This means you need special tools to identify which host runs each container. As you scale or redeploy, the containers often shift to different hosts, and all this happens within the cluster. Dynamic Deployment and OrchestrationĬontainer orchestration platforms like Kubernetes assign the best suited host in a cluster to each container. Container Monitoring Challenges Containers Add an Extra Infrastructure LayerĬontainers add a new layer to your infrastructure, which necessitates the use of application performance management (APM) tools to enable the automatic discovery of all running containers and the capture of any changes to container deployments in real time. In addition to tracking numeric error data, the solution should offer text-based descriptions of the issue in words. Containers that run HTTP servers require the collection of latency-related metrics and request counts.Ī comprehensive container monitoring solution will take into account the different layers of a stack and the functional requirements of each layer. Monitoring the performance of Docker and Kubernetes containers requires ratios for memory and CPU. IT teams can use information such as utilization ratios to decide when to scale up or down. Standard metrics covered by monitoring solutions include CPU usage and limit, memory usage and limit, and streaming logs provided in real time. How Does Docker Container Monitoring Work?Ĭontainer monitoring tools capture metrics and offer visualization and analytic capabilities to track activity.

A Docker container is not an operating system or application, so traditional monitoring tools are insufficient for handling performance monitoring in Docker.ĭocker monitoring requires the collection of various performance-related metrics from multiple components of a system, such as containers, hosts, and databases. They serve as miniature hosts that allow application components to run independently, but they also require complex configuration and networking. Docker containers are particularly useful for enabling rapid deployment and scaling environments.Ĭontainers are lighter weight than both physical and virtual machines, and their isolation offers additional security. Container monitoring is critical for ensuring uptime and performance of containerized applications, as well as for container security.ĭocker is a ubiquitous DevOps tool, providing containerization capabilities that include packing, shipping, and running applications within portable, lightweight, and insulated containers.
