Docker Monitoring with PRTG

Quick and easy container platform

Docker is gaining in popularity as a quick and easy container platform. One of the reasons network administrators love Docker technology is that it facilitates the separation of applications from the corporate infrastructure. If a hacker gains admin access via an application, he/she remains trapped inside the container – and the company network stays secure.

Docker packs applications (along with their dependencies and configurations) into containers, thereby making it easier to distribute them to all the employees of a firm. When applications are isolated inside a separate container infrastructure, the surrounding system is protected from hacks, no matter where the system happens to be.

An overview of all containers

Docker containers allow developers to develop in one place without interruption, to test, to manage workloads and important components, and to deploy new applications. These functions should work flawlessly for each of your containers! PRTG Docker monitoring helps by providing a constant overview of all your containers.

Special sensor for Docker environments

To reap maximum efficiency, security, and savings from Docker, you’ll need to monitor the availability and performance of its containers. There’s no need to purchase additional software - PRTG features a special, preconfigured sensor for Docker environments. This sensor lets you reliably manage and deploy dockerized applications.

With PRTG, everyone will work with peace of mind.

Monitoring

PRTG comes equipped with a special sensor for monitoring Docker containers. This sensor displays the statuses of your containers and provides you with regular updates. If necessary, it will also sound the alarm!

Secure connection

Select the desired container while creating a sensor, or configure sensors to monitor several containers at the same time. To do so, you’ll need a private key and certificate. Only then can you establish a secure connection from Docker to PRTG.

User-defined

The Docker Sensor uses lookups to determine the status values of one or more sensor channels. The possible statutes are defined in the corresponding lookup file. The behavior of a Docker sensor channel can be changed by editing these files.

All-in-one tool

All new software comes with potential risks, which can include anything from compatibility to security issues. PRTG is an all-in-one monitoring tool that includes a special built-in sensor for Docker monitoring. That means you can do away with having to rely on a variety of individualized solutions.

Stability

Docker technology allows for applications to be isolated in containers. For network administrators, these containers are secure and stable parts of their IT infrastructures which contribute to the overall stability of their company’s operations.

Control

Docker monitoring lets you oversee the deployment of dockerized applications to workstations in a number of different locations. If errors arise, you can intervene at once.

Clarity

Display the statuses of your Docker containers on an easy-to-read dashboard. Customize the dashboard, alarm, and reports feature – for yourself and the other stakeholders.

Responsiveness

PRTG sounds the alarm automatically – according to parameters defined by you beforehand – as soon as containers malfunction or performance problems arise. You can choose from any of the following alarm types: SMS, email, push notification, and more.

Automated reporting

PRTG monitoring helps companies ensure their Docker containers maintain an acceptable level of performance. Automated reports can be sent to the management team for this purpose.
