We're happy to announce that Tracetest now integrates with Elastic Observability APM. Check out this hands-on example of how Tracetest works with Elastic Observability APM and OpenTelemetry! Tracetest is a CNCF project aiming to provide a solution for deep integration and system testing by leveraging the rich data in distributed system traces.

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.

An Azure Load Balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM. Azure Load Balancers are frequently used in Azure Virtual Desktop (AVD) deployments. From our work with Azure Load Balancer, we think there are 4 key metrics and events you should proactively monitor and alert on.

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.

“If you are a managed service provider (MSP) in Switzerland, your customers are very likely Swiss customers, so they speak the local language, and they want their data to be in Switzerland, and they want your service provider to comply with all the Swiss regulations. And the same is true in 190 other countries, especially after last year,”

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.

Welcome to our first monthly product newsletter of 2023, SigNal - 21! Last month, we worked closely with our users to ship some advanced features which will enable our users to take advantage of their observability data more effectively. We were also trending on the front page of hacker news and got featured as one of the fastest-growing open source startups. Let’s dive in to see what humans at SigNoz were up to in the month of January 2023.

Java is a class-based object-oriented programming (OOP) language built around the concept of objects. OOP concepts are intended to improve code readability and reusability by defining how to structure your Java program efficiently. There are seven core principles of object-oriented programming, as follows.
