Jaeger

Jaeger is an open-source distributed tracing system for microservices. It provides a comprehensive view of requests as they flow through a distributed system, allowing developers to troubleshoot and optimize their applications. Jaeger is designed to be highly scalable and can handle large volumes of data. It supports multiple data storage backends, including Elasticsearch, Cassandra, and PostgreSQL. Jaeger also provides a web-based UI for visualizing and exploring traces, as well as a REST API for programmatically accessing tracing data. With Jaeger, developers can gain insights into their application’s performance and behavior, enabling them to identify and fix issues more efficiently.

Jaeger is particularly useful for microservices-based applications, where tracing can help developers understand how requests flow through the system and identify bottlenecks. It can also be used for monitoring and logging, providing a more comprehensive view of application performance and behavior.

Jaeger is widely used in the industry, with many companies and organizations adopting it for their distributed tracing needs. Its open-source nature and active community ensure that it remains a popular and widely-used tool for distributed tracing.
