The benefits of containers for cloud-based microservices are infinite. Container Monitoring is the process of tracing the performance of applications that are built on a microservices architecture. Containers are complex and more challenging to keep an eye on compared to traditional applications running on virtual servers.
Monitoring the performance of containerized applications to ensure application continuity is crucial. Monitoring becomes more effective through analyzing metrics, obtainer from any sources like host and demons logs, and monitoring agents installed on each node.
Container monitoring tools track container performance, collects event data, and measures the effects of container-sharing resources. Now Monitoring practices can be either proactive, reactive or adaptive. While Proactive monitoring sets protocols to prevent container failure, in Reactive monitoring we alert users by raising events when the containers fail. Adaptive monitoring continually assesses container performance and impacts from new components.
Like any other technologies, Containers are subject to performance degradation. The health of containerized applications directly impacts the health and business efficiency of a business. Monitoring application performance ensures that both the containerized applications and the infrastructure are always at optimum levels.
Monitoring Docker Containers helps in:

Around 2009, the term DevOps introduced an approach that enhances the collaboration between developers and operations groups. It came as a successor to the Agile method and ensured improvement to the Application Lifecycle Management process. You can consider DevOps as a strategy or principle that every company should implement within their delivery pipeline.
To implement DevOps, you should have the right tools and processes at your disposal to make it work efficiently. There are a variety of open-source DevOps tools that help in streamlining the development and deployment process. These open-source tools are built with enhanced collaboration that improves performance and allows you to handle different market needs.
Well, many companies across the globe have started adopting the DevOps approach for effective and faster delivery. However most companies still shy away from implementing open-source software within their organizations to enhance the DevOps approach. Also, companies restrain their developers from contributing to open source libraries, so they miss a huge opportunity for success.
We are sharing some key reasons why a company should focus on the Open-source adoption for Devops implementation.
Open-source is Free or low-costOpen-source means it is available freely or at a lower cost than other closed-source systems.
Based on open standardsWith open-source, you can find each tool, source code, and related troubleshooting documents easily. If you are still using traditional proprietary software, it will be difficult for your organization to evolve.
Open-source is self customizableOpen-source offers customizability where you can use tools and products that are way more efficient and light-weight than other available closed-source options. You can freely choose your framework and easily migrate and automate processes with open-source tools and frameworks.
The open-source community is expandingThe open-source community is now expanding, with millions of contributors and developers writing open code and development. Now companies are even supporting its exposure to their DevOps process. By joining open-source, you will become part of the most dynamic group that provides a better solution for every problem.
No Vendor monopoly or Vendor lock-inSince open-source tools are free from any proprietorship or licensing from any vendor, there is definitely no pressure of monopoly or being vendor locked-in. Whenever you feel to opt out of the open-source tool, you can move out without any restrictions.
Abundance of Talent poolSince open source software and tools are free and easily available, the number of people with an expertise on popular open source solution is more as compared to licensed tools( because fo the cost involved). So when looking for available expert talent pool in the market for your Devops toolchain, you have higher chances of success with open-source solutions.
There is no doubt that opting for open-source as a part of your DevOps process is beneficial to your organization. But if you are still using highly-proprietary and old traditional IT solutions, you may not achieve the success you are working for. Open source has opened the gate for DevOps to work efficiently. Below are the reasons why DevOps success aligns with the Open-source system, tools, and practices.
You can accelerate an existing system by using open-source tools within your DevOps. Below is the list of the open-source DevOps tools.
This tool offers software-related services like application deployment, configuration, etc. It allows you to automate IT tasks. You can easily integrate it with other DevOps tools. You can find its free version on GitHub, where Red Hat offers three different paid versions of Ansible.

Why Kubernetes is considered as the De facto standard for container orchestration?
Kubernetes has taken the container ecosystem by storm, and for good reasons. Kubernetes functions as the brain for your distributed container deployment. Kubernetes is a production-ready, open-source platform designed by Google’s using its accumulated experience in container orchestration.
Kubernetes has over 58K stars on GitHub & 2200+ contributors around the world. With the new ways of building & running applications, monitoring and observability strategies need to change.
Also monitoring Kubernetes, both the infrastructure platform and the running workloads, is on everyone’s checklist as we evolve beyond day zero and move into production.
What to Monitor?
We can try monitoring the following Kubernetes pod, node and cluster level metrices:
So here we bring for you some of the most popular Open-source monitoring tools to work with Kubernetes.
Originally built at the sound cloud, Prometheus is a monitoring and alerting toolkit. It is quite popular in the development community. Now, it is governed by the CNCF (Cloud Native Computing Foundation). Prometheus simplifies the process of pulling numerical metrics based on a time series from a given metrics endpoint. It has three elements: Prometheus server, Alert manager, and Exporters. Prometheus servers look after service discovery and pulling metrics from the exporters. The alert manager is responsible for setting up alert rules, analyzing the data in the Prometheus Db. It sends alert messages to multiple receivers if a certain rule is triggered. Exporters are independent containers that can be run on your target resource to generate & export metrics via metrics API. Prometheus is developed to collect time-series data via a pull model over HTTP. Here, multiple modes are available for graph and dashboard support.
You can monitor your Kubernetes cluster’s performance using Grafana. It is mostly used for matric analysis and visualization suite. It allows creating custom dashboards using data taken from multiple sources. The monitoring capabilities of Grafana include:
The ELK or Elastic stack is one of the most popular open-source solutions for logging Kubernetes. The ELK consists of the following things:
The enterprise version of ELK stack ships with X-pack, a set of additional tools that enables reporting, alerting, and role-based access control (RBAC). You need to use the previously mentioned enterprise version of the ELK stack to enable RBAC.
Fluentd is governed by a cloud-native computing foundation (CNCF). It is a specialized data collector that unifies data collection & consumption. Fluentd helps to better understand & use of data.
Additionally, Fluentd offers built-in metrics and general purpose output interfaces for centralized collectors. It is quite popular among Kubernetes users to Logstash’s facilities, especially those performances-related. Fluentd is a high performing, scalable &reliable.
It is quite easy to add new inputs or outputs with very little effect on performance. It uses disks or memory for buffering and queuing to handle transmission failures or data overload. It supports multiple configuration options to ensure a more resilient data pipeline.
cAdvisor is used to collect, process, and export resource usage and performance information about running containers. Like other agents, cAdvisor is not deployed per Pod but on the node level. It’s a basic tool but a very useful one. cAdvisor is built into Kubernetes and integrated into the Kubelet binary. It automatically detects every running container on a machine and collects system metrics like memory, CPU, network, etc.
cAdvisor is capable to support multiple endpoints despite having limited functionality. However, there are some cons of cAdvisor like it’s very basic, lacks analytical depth, and has limited functionalities.
Kubewatch watches the specific Kubernetes events and pushes notifications on these events to various endpoints. In simple words, Kubewatch is the go-to tool to receive push notifications on available collaboration applications or notification channels. Kubewatch is easy to configure and can be deployed using either helm or a custom deployment. It will take care of changes made to specific Kubernetes resources that you ask it to watch, like daemon sets, deployment, Pods, replica sets, replica controllers, services, secrets, and configuration maps. Users need to run it in their K8s cluster, and the event notifications will be received via webhooks.
Kube-Ops-View is not exactly a monitoring tool. It can’t be used to monitor and alert on production issues, it can give you a nice operational picture of your Kubernetes clusters. It will also have a look at the different nodes deployed and their status along with different Pods running on the nodes.
Kube-Ops-View provides a common operational picture for multiple K8s clusters. It shows the capacity and resource usage for nodes and individual pods with animation. However, it is not a replacement for Kubernetes Dashboard or a monitoring solution. It simply helps the users to quickly figure out the usage metrics without doing too much hustle.
It’s an end-to-end distributed tracing solution. Jaeger is widely acknowledged by Kubernetes practitioners as monitoring and troubleshooting best practices. The brief history of Jaeger is that it was developed by Uber, inspired by OpenZipkin and Dapper, and donated to CNCF. When a service failure occurs, you have no idea how the requests have gone from service to service over the network to complete a single business transaction. Debugging is extremely difficult in such conditions. Jaeger user tracing to enable root cause analysis, performance, and latency optimization. Jaeger is easy to use and provides a seamless user interface along with different instrumentation options.
Weave Scope is a troubleshooting and monitoring tool for Docker and Kubernetes. It was developed by Weaveworks. Weave Scope allows you to gain operational insights into your Kubernetes clusters. It takes a few steps ahead of Kube-Ops-View by providing a much easier and nicer user interface. It also provides the ability to manage containers and run diagnostic commands within the interface. Users can see the application, monitor the infrastructure. It is deployed on, and the relationships between the different components. Weave Scope is an effective tool for gaining context on your deployment. The only drawback of Weave Scope is that it lacks analytical depth.
It’s a Web-based, UI add-on for Kubernetes clusters. Users can create and manage workloads as well as do discovery, load balancing, configuration, storage, and monitoring. Kubernetes dashboard offers numerous features and is quite useful for small clusters & for people starting to learn Kubernetes. This tool offers different views for CPU and memory usage metrics aggregated across all nodes. This Dashboard is widely used to monitor the health status of workloads like pods, deployments, replica sets, etc. the installation process is quite easy and can be done using readymade YAML files.
Kube-state-metrics is a Kubernetes-native metrics service designed to listen to the Kubernetes. It generates metrics without any modification to Kubernetes API. Hence, users can rely on the same grade of stability as offered by Kubernetes API. Kube-state-metrics is an extremely essay to use and is only a metrics service. It requires a few more bit and pieces to become part of a complete monitoring solution for Kubernetes. Kube-state-metrics exports the metrics on the HTTP endpoint in a plain text format. Real-life Kubernetes practitioners recommend Kube-state-metrics if someone is struggling to use Prometheus for K8s monitoring.
In this blog post we have discussed the importance of Kubernetes monitoring and also outlined an extensive list of open-source monitoring tools for kubernetes. Finally choosing a tool depends on your monitoring needs and use cases. Open-source solutions have the advantage of being backed up by large communities driven to improve existing solutions.
