Docker is a flexible, scalable, open-source project for building, packaging, and distributing containerized applications. It's the most popular container platform among DevOps engineers because of its ability to efficiently automate the creation and deployment of containers.
However, because Docker allows applications to become encapsulated in self-contained environments, constant Docker container monitoring is required. Since isolation is done on the kernel level, resources are dynamically allocated. This makes it difficult for DevOps engineers to understand what's going on under the layers without a proper Docker monitoring software.
Docker container monitoring tools are crucial for maintaining performance efficiency and detecting performance problems. Choosing the right monitoring tool out of several Docker monitoring solutions will ensure increased health, performance and availability of your Docker containers. ManageEngine Applications Manager's Docker management software not only offers insight on the health and performance of Docker containers, it also enables Docker host monitoring through a robust monitoring, alerting, and analytics engine.
Unlike traditional host systems, Docker container hosts have a great deal of performance metrics that need constant monitoring. Most Docker host monitoring tools evaluate basic metrics, such as CPU usage, memory, networking information, and disk utilization for a running Docker container; however, a comprehensive Docker container monitoring tool like Applications Manager's Docker performance monitor goes a step further, providing details about all containers present in the Docker host.
It is essential to monitor Docker memory usage and network traffic to gain insight into utilization trends that help optimize the resource usage of Docker containers. Applications Manager's Docker managemenent software detects the containers in the Docker system, reads their statuses, and provides details about their health, availability, CPU, and disk usage.
Using Applications Manager's Docker application monitoring tool, you can monitor Docker memory usage and generate reports on active files, inactive files, cache, and memory paging that indicate operational efficiency. Plus, you can obtain network stats, like bytes transmitted and received, I/O written, I/O read, I/O total, and the number of packets dropped while transmitting and receiving.

Perceptive Docker monitoring tools like Applications Manager's Docker performance monitor can generate notifications based on the applied alerting rules on key metric data and can escalate issues through email or SMS. Thresholds can be designated for various container parameters, and alerts can be configured to trigger in the event of a threshold violation.
You can set up automated actions, such as starting, stopping, and restarting a container, to cut down the time and effort spent on recurring issues. Additionally, you can drill down with root cause analysis to fix the source of the problem and prevent future mishaps. With Applications Manager Docker application monitoring tool, you can establish dynamic baselines to detect anomalies and identify performance degradations in time to prevent major business catastrophes.
In addition to comprehensive Docker container monitoring, Applications Manager provides extensive reports on various performance parameters. With trend analysis reports, get historical data, heat charts, and statistical reports for various attributes, with which you can efficiently analyze performance trends. Unlike most Docker container monitoring tools, Applications Manager's Docker monitoring tool uses machine learning techniques to predict Docker container growth and utilization trends. This means you'll be notified when trends reach levels that are cause for concern so you can proactively allocate resources.
Applications Manager not only provides Docker monitoring solutions, but also offers holistic monitoring for virtualization platforms, databases, servers - application servers, web servers, cloud apps, middleware technologies, and much more.
