Docker monitoring simplified with Application Manager
Monitor Docker performance in real time and preempt issues before they arise
ManageEngine Applications Manager offers insight into the health and performance of Docker hosts and containers in dynamic microservice environments. It also helps you ensure optimal performance of applications running on Docker through a robust monitoring, alerting, and analytics engine.
Easy-to-deploy and agentless: Here's how to simplify Docker monitoring
Just enable the Docker Remote API and start monitoring Docker hosts and containers in Applications Manager. No need to install and maintain agents that can be intrusive and resource hogging. Auto discover containers and their dependencies and start monitoring performance easily. Since Docker allows applications to become encapsulated in self-contained environments, visibility into those applications is often veiled.
Key features of Applications Manager for Docker monitoring:
Obtain visibility into Docker containers on a deeper level
Gaining visibility into Docker containers on a deeper level presents unique challenges due to the dynamic and ephemeral nature of containerized environments. Traditional monitoring approaches often struggle to keep pace with the rapid creation, termination, and movement of containers, making it difficult to track their status and performance accurately.
Furthermore, monitoring Docker hosts, processes, and individual containers involves complexities such as understanding resource utilization, network activity, and application behavior within these isolated environments.
Applications Manager is a comprehensive Docker container monitoring tool that goes a step further to provide details about all containers present in the Docker host. Monitoring Docker containers and all of their related metrics will help reduce the occurrence of bottlenecks, thereby optimizing performance. Ensure smooth Docker deployments regardless of their location (AWS, Azure, GCP, or on-premises) or the orchestrator platform being used (Docker Swarm, Mesos, or Kubernetes).
Collect and Analyze Docker monitoring metrics with ease
With Applications Manager’s real-time performance insights, you can track the critical Docker performance metrics like resource usage, load distribution, container health, availability, response time, network traffic and many more. The tool’s detailed and accessible dashboards help you identify performance anomalies among attributes in real time. The docker monitoring capabilities of the tool let you observe the applications deployed in the containers in real time. It lets you access the performance of critical Docker KPIs in real time and analyze periodic data to understand performance as you go.

Quickly resolve Docker performance issues
Perceptive Docker monitoring tools, such as Applications Manager, can generate notifications based on applied alerting rules for key metric data, as well as escalate issues through email or SMS. Designate thresholds for various container parameters, and configure alerts to trigger in the event of a threshold violation. This proactive approach ensures timely awareness of potential issues, allowing for swift resolution and uninterrupted operation of your dockerized applications.
Using Applications Manager's fault management system, you can:
- Drill down with root cause analysis to fix the source of the problem and prevent future mishaps.
- Set up automated actions—such as starting, stopping, and restarting a container—to cut down the time and effort spent on recurring issues.
- Establish dynamic baselines to detect anomalies and identify performance degradations in time to prevent major business catastrophes.
Get insights into Docker resource usage and trends with Docker monitoring dashboard
In addition to comprehensive Docker performance 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 monitoring tools, Applications Manager 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.
