Browser instrumentation refers to collecting and analyzing data about a user's interactions with a web browser. This type of instrumentation involves using specialized tools and techniques to gather information about how a website is being used, such as page load times, network requests, and user interactions. The data collected through browser instrumentation can be used to improve website performance, identify and troubleshoot errors, and gain insights into user behavior.

Elasticsearch is a popular search engine that can be used to swiftly and almost instantly store, explore, and analyze huge volumes of data. It offers a distributed, multitenant full-text search engine with an HTTP web interface and schema-free JSON documents on top of Apache Lucene. In this tutorial, we will demonstrate how to communicate with an Elasticsearch cluster using a Python Elasticsearch client.

Welcome to our monthly product newsletter - SigNal 22! Last month our team worked on improving the logs tab and improved the correlation between telemetry signals to drive contextual insights faster. We were also trending on GitHub and crossed 2000+ developers in our slack community. Let’s dive in to see what humans at SigNoz were up to in the month of February 2023.

Monitoring and troubleshooting distributed systems like those built with microservices is challenging. Traditional monitoring tools struggle with distributed systems as they were made for a single component. Distributed tracing solves this problem by tracking a transaction across components. In this article, we will implement distributed tracing for a Java Spring Boot application with three microservices.

OpenTelemetry consists of several main components. But to understand the architecture, we will start by understanding some of the key design principles behind the design and architecture of OpenTelemetry. But before that, let us have a brief overview of OpenTelemetry.

Observability vs monitoring has been a common topic in DevOps recently. There has been a lot of debate, and I have learned a lot from them when I started my observability journey. Most literature on observability is associated with a particular product or shares a textbook definition. In this blog post, I want to give you a practical understanding of observability and the differences between observability and monitoring with different scenarios and examples. We will cover the following topics here.

Loki and Prometheus are both open source tools. While Loki is a log aggregation tool, Prometheus is a metrics monitoring tool. Loki’s design is inspired by Prometheus but for logs. This blog post compares the two common monitoring tools Loki vs Prometheus, to help you understand their key differences. Log management and metrics monitoring are critical aspects of monitoring a software system effectively.

Docker logs play a critical role in the management and maintenance of containerized applications. They provide valuable information about the performance and behavior of containers, allowing developers and administrators to troubleshoot issues, monitor resource usage, and optimize application performance. By capturing and analyzing log data, organizations can improve the reliability, security, and efficiency of their containerized environments.

Structured logging is the method of having a consistent log format for your application logs so that they can be easily searched and analyzed. Having structured logs allows for more efficient searching, filtering, and aggregation of log data. It enables users to extract meaningful information from log data easily. Logging is an essential aspect of system administration and monitoring. Logging allows you to record information data about the application's activity.

Winston Logger is one of the most popular logging libraries for Node.js. It is designed to be a simple and universal logging library supporting multiple modes of transport. A transport is essentially a storage device for the logs. Each logger can have multiple modes of transport configured at different levels. For example, one may want error logs stored in a database, but all logs output to the console or a local file. Some of the features of Winston logger are.
