Best Docker Container Monitoring Tools

Docker has become one of the most widely-used containers in the world but it isn’t without its challenges.

The best Docker container monitoring tools help eliminate this lack of transparency. Monitoring services located somewhere between the host and the application layer is tricky without the right software.

Here is our list of the best Docker Container monitoring tools:

Before we look at the tools themselves we’re going to look at why you need to monitor Docker.

Why do I need to monitor Docker containers? 

In just a matter of years, user experience expectations have risen to unprecedented levels. Users aren’t satisfied with anything less than applications that perform seamlessly. However, living up to expectations and delivering a high-quality user experience requires ongoing maintenance and performance management.

If you don’t have a Docker monitoring tool then you don’t have a point of reference to make sure that performance is up to scratch. In other words, you won’t be able to measure its performance. Without the necessary visibility, you won’t have the tools you need to stave off performance degradation and poor user experience.

In addition, with the necessary visibility, you will also be able to detect performance issues at the production level and benefit from long term capacity planning.

The best Docker container monitoring tools

Our methodology for selecting a Docker container monitor

We reviewed the market for Docker container monitoring systems and analyzed tools based on the following criteria:

  • The ability to collect activity data from within a Docker container
  • Server resource monitoring
  • Network performance logging
  • Correlation between system resources and Docker activity
  • The ability to monitor other container brands and virtual systems
  • A free trial or a demo package that provides a way to try the system before buying
  • Value for money from a monitoring tool that fully tracks Docker activity and is offered at a reasonable price

With these selection criteria in mind, we identified container monitors that can track the performance of a range of virtual systems, including Docker.

1. SolarWinds Server & Application Monitor (FREE TRIAL)

2. AppOptics Docker Monitoring with APM (FREE TRIAL)

AppOptics Docker Monitoring with APM

AppOptics is a cloud-based application monitoring service run by SolarWinds. The system was formed in 2017 through the combination of Librato and TraceView. AppOptics is marketed at two levels of service. The upper level of the service is called APM, which is an application performance monitor. The lower level plan of AppOptics is called AppOptics Infrastructure. The Infrastructure system is included in the APM plan. Docker monitoring is included in AppOptics Infrastructure.

Key Features:

  • Dependency Mapping: Between applications and services
  • Infrastructure Module: Includes Docker monitoring
  • Correlates Activity with Resource Availability: Looks at each application’s resource usage
  • Graphs for Container Activity: See performance over time

Why do we recommend it?

AppOptics Docker Monitoring with APM is the higher of two plans of the AppOptics service. SolarWinds has two packages that provide very similar services because the Server & Application Monitor covers much the same work as AppOptics. The lower Infrastructure edition provides Docker monitoring and the APM includes that plan.

The AppOptics system requires an agent program to be installed on the monitored system. This agent is called the SolarWinds Snap Agent. This agent is able to track resource usage by Docker containers through the inclusion of a Docket plug-in, which is available for free with AppOptics Infrastructure but needs to be enabled and configured.

The Docker plug-in reports on server statuses as they relate to docker activity. These factors include CPU usage and memory activity for each container and for Docker overall. The plug-in also reports on server I/O activity and network statistics, such as the number of packets sent from the server for a container and the number of packets lost.

If you just want to monitor Docker, then the AppOptics Infrastructure plan will be enough. However, if there are other applications that you feel could be delivered more efficiently, then you should check out AppOptics APM, which also gets you the Docker-monitoring Infrastructure package.

Who is it recommended for?

SolarWinds charges for AppOptics by subscription, which makes it more affordable than the Server & SApplicaiton Monitor. This system also runs on Windows Server and will monitor cloud systems as well as on-premises assets. The Infrastructure plan is less than half the price of the APM.

Pros:

  • Offers Great Visualizations: Displays live and historical health metrics and resource consumption
  • Scalable: Built as a cloud service with subscription pricing per host
  • Tracks All Major Resources: CPU, memory, and network usage
  • Virtual System Monitoring via Plug-Ins: Can monitor Docker, AWS, Azure, and Hyper-V

Cons:

  • No Kubernetes Monitoring: Would be useful for deployment monitoring

AppOptics is a subscription service with charges levied in advance. The AppOptics APM plan is more expensive than AppOptics Infrastructure. You can get a 14-day free trial of the full AppOptics APM service to see whether you need the full services of that package or could get all of your requirements fulfilled with just the Infrastructure module.

Datadog combines Docker monitoring with applications, server, and network monitoring to get a full-stack monitoring suite.

Key Features:

  • Tracks Container Creation and Destruction: Stores activity metrics for historical analysis
  • Server Resource Monitoring: Looks at the availability of the services that Docker needs in order to operate
  • Alerts for Performance Problems: Can be sent as notifications by email, Slack, or PagerDuty

Why do we recommend it?

Datadog Docker Monitoring is a very close competitor to the Site24x7 system. This service is part of the Infrastructure module on the Datadog platform. This package can be expanded by integrations. However, Docker monitoring is part of the core package of the system. The Docker instances can be based on premises or on cloud systems.

Dashboards are drag-and-drop so they can be customized according to what you want to see. To help diagnose performance issues more easily, Datadog grants you visibility over application code performance. In addition, you can also view CPU and memory forecasts to help you implement capacity planning over the long term.

The alerts system included with the program is also of high quality. You can set alert thresholds to dictate when alerts are generated. To reduce the likelihood of false positives Datadog takes into account regular fluctuations that could trigger a false alarm. The advantage of this is that you only see legitimate alerts.

Who is it recommended for?

Datadog provides a Free edition of its Infrastructure Monitoring package, which will attract small businesses. This plan allows the monitoring of up to five hosts, so it offers the same service as the Sematext platform. The Free system doesn’t include access to the integration library.

Pros:

  • Cloud-Based SaaS Product: Allows monitoring with no server deployments or onboarding costs
  • Cloud Monitoring: Will monitor Docker containers hosted on cloud platforms
  • High-Frequency Polling: Gather Docker activity data every 15 seconds

  • Alerts for Performance Problems: Live attack warnings

Why do we recommend it?

The CrowdStrike Falcon Cloud Workload Protection Platform (CWPP) is a monitoring tool that provides both performance tracking and security monitoring for cloud services. This service provides monitoring for Docker and other containers as well. This system will also monitor Docker running on your servers.

The container identification and monitoring service is useful and you might end up thinking this is the sole purpose of the CrowdStrike service. However, this is just the beginning. While tracking containers, the service also assesses them. It will produce recommendations on how to tighten up the settings of your containers and their related management in Kubernetes. The system will also watch where they run and any attempts to access or interfere with them.

If an attack is launched against your Docker system or a specific container, the CrowdStrike system spots this unusual activity and begins a trace. It can chain back through command execution and running processes to identify the account from which they were launched and examine all other activity by that user. This quickly identifies a threat that can be isolated by shutting down the account and killing all of the processes that it launched. Reaction is instant and automated and everything is documented.

Who is it recommended for?

This cloud system is able to monitor on-premises Docker instances, but it is primarily designed for the protection of cloud-based assets. Therefore, it is recommended for businesses that manage cloud-based assets and particularly for those that provide their own software as SaaS packages.

Docker container monitoring FAQs

How does Docker provide isolation?

Docker provides isolation through a system of “namespaces.” The actual isolation structure is called a “container.” Thing of a container like a cardboard box that someone would use to carry a collection of their items. There is a set of namespaces for each container and they mediate with the surrounding environments, preventing direct contact with the container and external services.

Is Docker a security risk?

There are security risks involved in using Docker because one compromised container opens up a possible avenue to other containers operating in the system and also to the host. This is similar to the security risks on a network, where one compromised endpoint makes the entire network and all of its equipment vulnerable to attack. Therefore, it is important to implement security features within Docker to strengthen the security of each container.

Are Docker images secure?

Not all Docker images are secure. Be careful where you get them from. When making your own Docker structures, be sure to limit the access rights of its contents and implement appropriate security measures.

How do I prevent root access to my Docker container?

It is safer to run your Docker container as a non-root user. By default, the Docker system inherits the privileges from the user account that launches it. The settings of a container can impose further resource access limits.
