Here are some ways to monitor and analyze a Docker instance running in a single Azure VM:

Azure Monitor: Azure Monitor is a built-in monitoring solution provided by Azure. It can be used to monitor the performance and health of your Azure VM and Docker instance. Azure Monitor provides real-time monitoring of CPU usage, memory usage, disk usage, and network traffic. You can also set up alerts to notify you when certain thresholds are exceeded.

Azure Log Analytics: Azure Log Analytics is another built-in monitoring solution provided by Azure. It can be used to collect and analyze log data from your Azure VM and Docker instance. You can use Log Analytics to monitor the logs of your Docker containers and identify any errors or issues.

Docker Stats: Docker provides a built-in command called "docker stats" that can be used to monitor the resource usage of running containers. This command provides real-time information on CPU usage, memory usage, network I/O, and disk I/O. You can use this command to monitor the resource usage of your Docker instance and identify any performance issues.

Docker Logs: Docker also provides a built-in command called "docker logs" that can be used to view the logs of running containers. This command provides real-time information on the output of the container's stdout and stderr streams. You can use this command to monitor the logs of your Docker instance and identify any errors or issues.

Docker Healthchecks: Docker provides a feature called "healthchecks" that can be used to monitor the health of running containers. Healthchecks are scripts or commands that are run periodically to check the health of the container. If the healthcheck fails, Docker will automatically restart the container. You can use healthchecks to monitor the health of your Docker instance and ensure that it is running smoothly.

Third-party Monitoring Tools: There are several third-party monitoring tools that can be used to monitor Docker instances running in Azure VMs. Some popular Docker monitoring tools include Prometheus, Grafana, and Datadog. These tools provide more advanced monitoring and analysis capabilities than the built-in Docker commands.

I hope this helps!
