Spans are fundamental building blocks of distributed tracing. A single trace in distributed tracing consists of a series of tagged time intervals known as spans. Spans represent a logical unit of work in completing a user request or transaction.

Elasticsearch and MongoDB are popular document-oriented databases. While Elasticsearch is known for its advanced indexing and search capabilities, MongoDB is one of the most established NoSQL databases.

Tools like Fluentbit and Fluentd make log management more efficient by centralizing log data from multiple sources and providing the ability to monitor and analyze it all in one place.

In this article, we will use OpenTelemetry to instrument a sample Flask app. Flask is one of the most popular web application frameworks of Python. It consists of Werkzeug WSGI toolkit and Jinja2 template engine.

Logs are an integral part of any system that helps you get information about the application state and how it handles its operations. The goal of this blog is to compare the commonly used logging solutions, i.e., ElasticSearch (ELK stack) and Loki (PLG stack), with SigNoz on three parameters: ingestion, query, and storage.

In this tutorial, we will learn about Docker container lifecycle. But first, let me share a personal anecdote. On a hot summer afternoon in 2021, my manager called me out of the blue and said, “Muskan, the project file you shared with me is not working on my machine. Could you please come over and fix the setup? It’s really urgent.” I rushed to his cabin and tried my best but could not fix the dependencies issues.

OpenTelemetry and Prometheus are both open-source projects under Cloud Native Computing Foundation. In this article, let us understand the key differences between the two projects and explore their advantages and shortcomings.

The kubectl logs tail command is a tool that allows users to stream the logs of a pod in real-time while using Kubernetes. This command is particularly useful for debugging and monitoring applications, as it enables users to view log output as it is generated and quickly identify any issues or problems with their application.

OpenTelemetry can be used to trace Go applications that use Kafka to find performance issues and bugs. OpenTelemetry is an open-source project under the Cloud Native Computing Foundation (CNCF) that aims to standardize the generation and collection of telemetry data. Telemetry data includes logs, metrics, and traces.

Docker containers are transient (lasting for a very short time), spawning quickly and in high numbers, which causes metrics bursts. This makes monitoring a challenge due to Docker's scaling and redeployment features. Docker stats is a built-in feature of Docker containers. The docker stats command returns a live data stream of your running containers.
