Top open-source tools like Prometheus, Grafana, Jaeger, ELK Stack, cAdvisor, and Zabbix make it simpler to track Kubernetes and Docker in 2025. These tools help quick log analysis, tracking of performance, and system problem solving. They improve troubleshooting, increase system reliability, and reduce resource usage. By using them, containerised environments may work more efficiently and with improved visibility.
6 Open-Source Tools to Track Kubernetes and Docker in 2025
1. Prometheus : Famous for its strong time-series data collection and storage capabilities, Prometheus is a top freely available tracking and alerting toolkit. It effectively collects current statistics from Kubernetes clusters using a multi-dimensional data model and a robust query language (PromQL), offering insights into performance, use of resources, and possible bottlenecks. Its smooth operation across environments is provided by its native integration with Kubernetes.
2. Grafana : Grafana is an open-source platform for monitoring and data representation that lets users create and share dashboards that are flexible and adjustable. Grafana facilitates the presentation of complex metrics and helps with system performance analysis when used in combination with Prometheus. It is a flexible tool for Kubernetes and Docker environment tracking due to its support for many sources of data and extensive visualisation choices.
3. Jaeger : Uber Technologies developed the open-source, end-to-end global tracking technology known as Jaeger. It helps with speed reduction and performance efficiency in microservices-based distributed systems by tracking and debugging them. Multiple data storage backends and different deployment situations, such as Kubernetes and Docker, are supported by Jaeger's components, which represent a tracing client library, collector, query service, and web-based user interface.
4. ELK Stack : This popular open-source solution for centralised logging and log analysis includes Elasticsearch, Logstash, and Kibana. Kibana offers an internet-based user interface for data visualisation, Logstash manages and transfers data, and Elasticsearch functions as a distributed search and analytics engine. When combined, they provide an entire framework for tracking and analysing logs from Docker and Kubernetes systems, improving application visibility.
5. cAdvisor (Container Advisor) : This open-source tool offers real-time tracking and analysis of container performance and resource utilisation. It was created by Google and provides full data on network input/output, CPU use, and memory usage for every container that is operating on a host. A useful tool for monitoring containerised applications, cAdvisor is lightweight and adaptable with multiple container runtimes, such as Docker and Kubernetes.
6. Zabbix : Zabbix is an open-source monitoring program that offers enterprise-level solutions for keeping an eye on servers, networks, apps, and cloud services. For effective processing, it provides a centralised system that keeps data in a relational database. Zabbix is a multipurpose solution for thorough infrastructure monitoring because of its features, which include network, server, cloud, application, and service monitoring.
Conclusion
Kubernetes and Docker system handling and tracking can be greatly improved by implementing these open-source tools into practice. They provide proactive maintenance and optimisation by offering comprehensive knowledge into system performance, use of resources, and application health. Organisations may ensure the reliability and efficacy of their containerised applications in 2025 as well as later by using these tools.
