Understanding Container Monitoring Tools: What You Need to Know 2024

Each microservice operates within its container, completing orders, inventory control, and payment processing. A broken reputation, disappointed clients, and lost sales could result from one of these containers slowing down or crashing.

Here’s where container monitoring tools come into play. They closely monitor your containerized apps’ health and performance, warning you of problems before they become serious. Additionally, they let developers create apps in one setting, launch them in another, and use them anywhere.

With Docker and Kubernetes rapidly on the rise, it’s crucial to get container monitoring and log management right from the start. Knowing these monitoring tools is crucial as containerization gains speed in contemporary cloud environments.

The following article will discuss their importance, their functioning, the Top 15 container monitoring tools you can use for your computing needs, and the important metrics they monitor to help you efficiently manage your containerized apps.

Let’s Understand What Is Container Monitoring?

Container monitoring is the process of regularly gathering metrics and monitoring the state of microservices environments and containerized apps to make sure they are performing well and are healthy.

The metrics gathered are regularly tracked in real time and then analyzed to assess whether an application is completing its objectives.

An application performance management (APM) solution that provides IT teams with a quick perspective to quickly create and deploy apps using DevOps principles is a container monitoring service.

The Role of Docker in Container Monitoring

We must explore the role of Docker in Container Monitoring, it makes the process of building, deploying, and maintaining containers easier, and Docker has become the industry standard for containerization.

It is easy to run applications in any environment by using Docker to package dependencies and applications into a single container.

Because of Docker’s growing popularity, specific container monitoring solutions have been created to keep an eye on Docker containers. These tools monitor parameters unique to Docker, like resource utilization, performance trends, and container health.

This makes it possible for organizations to maintain optimal application performance and get a deeper insight into their Docker environments by using these monitoring tools.

Why Use Container Monitoring Tools?

Organizations can make better decisions by having a better understanding of what’s happening not only at the host or cluster level but also within the container runtime and application.

Operators of containerized platforms benefit immensely from having visibility into logs, traces, and analytics. Examples of these decisions include when to scale up or down instances, tasks, and pods, adjust the type of instance, and make on-demand, reserved, and spot purchases.

Key Benefits of Container Monitoring Tools

• Assurance Performance and Stability: To avoid delays or crashes, keep an eye on the functionality and health of containerized apps in real-time.
• Optimize Resource Implementation: By balancing CPU, memory, and storage utilization, tools assist make sure containers operate effectively without using excessive or insufficient amounts of resources.
• Reduce Downtime: Receive notifications when problems arise with containers so that prompt solutions can be made before they cause problems. An e-commerce platform, for example, can stop service interruptions during periods of high demand.
• Scale Effectively: Keep an eye on resource consumption and automatically adjust container sizes to satisfy user requests, guaranteeing a seamless user experience even at busy times.
• Active Problem Detection: This helps businesses maintain a high degree of service reliability by identifying and correcting possible problems, like resource bottlenecks before they affect users.
• Monitor Key Metrics: To keep things running smoothly, tools like Prometheus or Grafana offer insights into CPU, memory, and network traffic usage, among other things.

You can debug your code in real time without sampling by using the Pixie tool. For example, you will need to install New Relic’s Kubernetes integration to view how your nodes, pods, containers, and the application interact.

12. Jaeger

Jaeger excels when compared to many container monitoring tools as it is highly focused on distributed tracing, a tool available as open-source software that is used to track and diagnose transactions in distributed systems.

Teams at Uber developed it, and in 2015, it became available to the public. Jaeger is a graduation project from the Cloud Native Computing Foundation.

Multiple requests from different services can be made during a single call. Large-scale transactions and distributed architectures, such as cloud-native microservices, are two areas in which Jaeger excels.

Traditional container monitoring tools tracked metrics such as CPU, memory, and network usage but Jaeger will give deep insights into how requests flow with complete visibility of every request lifecycle from other microservice-containerized environments.

13. CloudWatch (AWS)

An observability and monitoring service provided by AWS is called Amazon CloudWatch. You can set alerts, monitor and collect log files, track metrics, and react to changes in your CloudWatch in AWS resources.

For effective management and monitoring of your AWS resources, AWS CloudWatch is a necessary service. Your infrastructure and apps can operate more reliably, perform better, and spend less money if you deploy CloudWatch correctly.

CloudWatch works by collecting logs and metrics from your AWS resources, evaluating the information, and delivering alerts and visualizations.

It is made up of three primary parts:

• the metrics and monitoring section that gathers data from resources,
• the CloudWatch long-term storage of that data,
• the visualization and alert sections that are dependent on the data that has been stored.

You get free storage of the metric data with a 1-minute granularity for a maximum of 15 months.
