海外TECH	DEV Community	Docker Stats | Understand how to monitor Docker Metrics with docker stats	https://dev.to/signoz/docker-stats-understand-how-to-monitor-docker-metrics-with-docker-stats-1h2l	Docker Stats Understand how to monitor Docker Metrics with docker statsDocker containers are transient lasting for a very short time spawning quickly and in high numbers which causes metrics bursts This makes monitoring a challenge due to Docker s scaling and redeployment features Docker stats is a built in feature of Docker containers The docker stats command returns a live data stream of your running containers Docker is a containerization platform that lets you separate your applications from your infrastructure to deliver software quickly To monitor Docker it is crucial to gather performance related metrics from various system elements such as containers hosts and databases Methods of monitoring Docker MetricsThere are several ways in which Docker metrics can be monitored These include Docker stats commandPseudo files in sysfsREST API exposed by the Docker daemonNote that these are in built features of Docker Observability for your containerized applicationObservability is critical for modern cloud native applications It helps engineering teams have more confidence in their production environment Troubleshooting performance issues is easier with a robust observability framework in place SigNoz an open source observability tool can help make your containerized applications observable In this article we will deep dive into the docker stats command that can be used to monitor Docker metrics right from the terminal What is the docker stats command The docker stats command is a built in feature of Docker that displays resource consumption statistics for the container in real time By default it shows CPU and memory utilization for all containers Stats here refers to “statistics You can restrict the statistics by entering the container names or IDs you re interested in monitoring The docker stats command output includes CPU stats memory metrics block I O and network IO metrics for all active containers A Practical ApproachRunning the docker stats command produces an output that looks like the code snippet below This command shows the stats for all the running Docker containers docker statsCONTAINER ID NAME CPU MEM USAGE LIMIT MEM NET I O BLOCK I O PIDSbfbsd nginx container MiB GiB B B kb B bc ubuntu MiB GiB kb B MB B afcbae hello world MiB GiB kb B kb B Understanding the docker stats command outputThe docker stats command returns a live snapshot of resource usage by Docker containers Let s break down all the stats given by the command CPU statsCPU is expressed as a percentage of the overall host capacity One can optimize the resource usage of Docker hosts by being aware of how much CPU the hosts and containers consume One active busy container shouldn t slow down other containers by consuming all of the CPU resources Containers can be optimized based on the amount of CPU they are using MEM USAGE LIMIT StatsMEM USAGE lists the available memory It gives a quick overview of the container s memory usage and allocation providing information about the container s memory statistics including usage and memory limit Except when it is defined for a specific container the memory usage limit corresponds to the host machine s memory limit MEM StatMEM shows the memory percentage that the container is using from its host machine Network NET I O StatsNET I O shows the volume of information the container s network interface has transmitted TX and received RX It represents network traffic BLOCK I O StatsBLOCK I O helps to identify containers that are writing data and shows the total number of bytes read and written to the container file system Block I O stats can give you an idea about issues with data persistence PIDSPIDS is a count of the processes that the container has created or the number of kernel process IDs running inside the corresponding container More on the usage of docker stats Getting stats of a particular containerTo get the stats of a particular container provide the container Id and run the command docker stats lt containerID gt docker stats bfbsd CONTAINER ID NAME CPU MEM USAGE LIMIT MEM NET I O BLOCK I O PIDSbfbsd nginx container MiB GiB B B kb B You can also get the stats of multiple containers by name and id if you rundocker stats lt containerName gt lt containerId gt docker stats ubuntu bfbsdCONTAINER ID NAME CPU MEM USAGE LIMIT MEM NET I O BLOCK I O PIDSbc ubuntu MiB GiB kb B MB B bfbsd nginx container MiB GiB B B kb B Display options that Docker ProvidesThese display options allow you to specify how you want the output to be shown Docker stats offers the following options for display all which shows all containers whether stopped or running format which uses the Go Template syntax to print images out no stream which disables streaming stats and only pulls the first result no trunc which instructs Docker not to truncate shorten output The syntax for this is shown below docker stats OPTIONS CONTAINER Using docker stats formatLet s take a look at the format option Docker format is used to modify the output format of commands that have the format option If a command supports this option it can be used to change the output format of the command to suit our needs since the default command does not display all the fields connected to that object By using the Go Template syntax the formatting option format presents container output in an easy to read way For example docker stats format Container CPUPerc bc bfbsd This prints out all images with the Container and CPUPerc CPU Percentage elements separated by a colon and it uses a template without headers To display all container information in a table format including name CPU percentage and memory consumption use the following syntax docker stats format table Container t

PIDsNumber of PIDs Not available on Windows Final ThoughtsIn this article we discussed ways to monitor resource usage metrics in Docker focused on the docker stats command Other ways of using The Docker stats Pseudo files in sysfs and REST API exposed by the Docker daemon are native ways of monitoring resource utilization metrics Docker container monitoring is critical for running containerized applications For a robust monitoring and observability setup you need to use a tool that visualizes the metrics important for container monitoring and also lets you set alerts on critical metrics SigNoz is an open source observability tool that can help you do that It uses OpenTelemetry to collect metrics from your containers for monitoring OpenTelemetry is becoming the world standard for instrumentation of cloud native applications and it is backed by CNCF foundation the same foundation under which Kubernetes graduated If you want to set up a robust observability framework for your containerized application you can use SigNoz You can create unified views to monitor your Docker containers effectively You can check out the SigNoz GitHub repo here Further
