The three challenges in container management

Containers are short-lived

Containers are short-lived

Containers can be quickly provisioned, moved between hosts, or destroyed, in which case their data disappears with them. By nature, this makes it hard to track changes and monitor their status, making the real time collection of data and the auto-discovery of new instances a desired, even necessary, feature.


Monitoring resource usage and allocation is crucial

Monitoring resource usage and allocation is crucial

Resources are shared between the host and all containers, but each container can have its own limits for resources like CPU or memory usage, and you need to monitor them individually. The host may not be using all the available resources, but a container may be struggling against its own constraints, which will lead to poor performance.

Log collection and management is essential

Log collection and management is essential

Container logs are sent to the default output and error streams of the host operating system. Those streams need to be collected, adequately processed, and tagged with metadata like the container name and ID for later processing. And this needs to be done for each and every container running in your network.


Visualize your Docker monitoring in real time

With the PRTG Docker Container Status sensor, you can monitor the container status (Create, Running, Paused, Restarting, Exited), availability and downtime, the CPU utilization, incoming/outgoing packets and data traffic, memory usage, and other metrics with ease. 

How PRTG defines sensors (FAQ) 



How PRTG can help you with Docker container monitoring

User-defined monitoring metrics

User-defined monitoring metrics

The Docker Container Status sensor uses lookups to determine the status values of one or more sensor channels. The possible states are defined in the corresponding lookup file, and you can always customize the behavior of the respective sensor channel by editing the file.


Preconfigured sensor included

Preconfigured sensor included

To monitor your Docker containers with PRTG, you can use the Docker Container Status Sensor. This sensor supports the IPv4 protocol and has a low impact on performance. 


Secure connection

Secure connection

To establish a connection between the Docker Container Status sensor and your container, you need to provide certificates and private keys. Follow the steps in our Knowledge Base Article.

3 reasons why PRTG is the perfect Docker container monitoring tool

One tool to monitor them all

One tool to monitor them all

PRTG is an all-in-one IT infrastructure monitoring tool that includes a special built-in sensor for monitoring your Docker environments. That means you can do away with having to rely on a variety of individualized solutions, which can carry potential risks such as incompatibility with your current workflow and even security issues. 

Your containers at a glance

Your containers at a glance

PRTG features an easy-to-read main dashboard with an overview of all your containers and their data at a glance. And with the auto-discovery, PRTG can automatically track new containers as they are deployed. 

You can customize dashboards to your needs and share them via a unique URL that that can be used for internal or external access. Publish the dashboard internally for colleagues or the management team, or show it on network operation center screens, for example.

Sound the alarm

Sound the alarm 

PRTG automatically triggers configurable alerts based on metrics defined by you. As soon as performance or reliability issues arise, you will be informed by SMS, email, push notification, and more.

You can also schedule automated reports that PRTG generates for you to send them, for example, to the management team.

The container monitoring FAQ


1. What are containers?

Containers are a way of packaging applications and all its dependencies (such as libraries and configuration files) into bundles that can be easily deployed and run across a variety of environments. This increases application portability and operational efficiency. A containerized application will run the same on any host, ending the "it works on my machine" dilemma.

2. What is Docker?

Docker is an open-source platform for building, deploying, and managing containers. Since the original release in 2013, the platform has been used by more than 13 million developers, who have developed more than 7 million applications.

3. What is the main difference between containers and virtual machines?

Containers only include what is needed to run the application and share resources with the host OS, so they use less resources when compared with Virtual Machines (VMs). A typical container image can be tens of megabytes in size, while a similar VM image can occupy tens of gigabytes.


Because they are lighter than virtual machines, you can run more containers than VMs on a given host. This way, you can optimize your resource usage and save money on infrastructure costs.

4. How can containers increase my network security?

Containers allow for increased security since application processes are isolated inside the container. So, even if a hacker manages to break into a containerized application, he will still be separated from the underlying operating system and from your corporate network.

5. Why do I need a container monitoring tool?

You need a container monitoring tool for the same reasons you already use a network monitoring tool: to increase the availability of your applications by proactively identifying issues and quickly reacting to events, and to ensure that they are running at their best by monitoring their resource usage and behavior through time.

6. What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.


PRTG the multi-tool

PRTG: The multi-tool for sysadmins

Adapt PRTG individually and dynamically to your needs and rely on a strong API:

  • HTTP API: Access monitoring data and manipulate monitoring objects via HTTP requests
  • Custom sensors: Create your own PRTG sensors for customized monitoring
  • Custom notifications: Create your own notifications and send action triggers to external systems
  • REST Custom sensor: Monitor almost everything that provides data in XML or JSON format
