Getting Started with Loki for Log Collection

In modern cloud-native applications, collecting and managing logs is essential for monitoring, debugging, and gaining insights into how applications perform. Loki, a log aggregation system inspired by Prometheus, is designed for efficiency and ease of use, especially in conjunction with Grafana for visualization. This article explores the basics of using Loki for collecting logs in your applications. What is Loki? Loki is an open-source log aggregation system that stores logs as streams.

Using Prometheus Remote Write API: A Practical Example

Prometheus is an open-source monitoring and alerting toolkit designed for reliability and scalability. With its powerful querying language and data model, it has become a staple in the DevOps and SRE communities. One of the key features of Prometheus is its Remote Write API, which allows for the efficient forwarding of time series data to external systems. This article explores how to set up two Prometheus instances, where one instance sends its metrics to another using the Remote Write functionality.

Building Simple Applications with Node.js and MQTT

In the evolving world of Internet of Things (IoT) and real-time applications, MQTT (Message Queuing Telemetry Transport) has emerged as a lightweight messaging protocol that’s perfect for small sensors and mobile devices. In this article, we’ll explore how to develop simple Node.js applications that communicate through an MQTT broker. This will give you a basic understanding of both MQTT and Node.js while allowing you to set up a simple messaging system between two applications.

Building a Simple Java Application with RabbitMQ Communication

In the world of microservices architecture, effective inter-service communication is essential for building robust applications. RabbitMQ is a widely used message broker that implements the Advanced Message Queuing Protocol (AMQP), allowing different applications to communicate with one another seamlessly and reliably. In this article, we will build a simple Java application consisting of two services that communicate with each other using RabbitMQ. Prerequisites Before we dive into the code, ensure you have the following installed:

Replacing Alertmanager with Grafana Alerts: A Comprehensive Guide

In modern DevOps environments, monitoring and alerting are crucial for maintaining system health and performance. Traditionally, Alertmanager has been used alongside Prometheus to handle alerts. However, more organizations are exploring the use of Grafana Alerts due to its seamless integration with Grafana dashboards and a more user-friendly interface. This article outlines the steps to replace Alertmanager with Grafana Alerts, discusses the benefits, and highlights potential challenges. Overview of Alerting Systems Alertmanager Alertmanager is a key component of the Prometheus stack.

Building Simple PHP Applications Communicating via RabbitMQ

Introduction In modern application development, building microservices that communicate with one another efficiently is critical. Messaging systems like RabbitMQ have become a standard approach, facilitating asynchronous communication. In this article, we will examine how to create a simple PHP application where two separate PHP scripts communicate with each other using RabbitMQ. What is RabbitMQ? RabbitMQ is an open-source message broker that implements the Advanced Message Queuing Protocol (AMQP). It enables apps to communicate and share information despite being loosely coupled.

Building a Simple Python App to Relay AMQP Messages to Slack

In today’s cloud-native environments, services often communicate over various protocols. One common use case is to receive messages from an AMQP (Advanced Message Queuing Protocol) broker and relay those messages to a channel on Slack. This article will walk you through the process of building a simple Python application that fulfills this task. Overview We’ll create a Python application that listens for messages from an AMQP broker (like RabbitMQ) and sends them to a designated Slack channel using Slack’s Incoming Webhooks.

Building Simple Go Applications with RabbitMQ Communication

Introduction In the world of distributed systems, inter-process communication is vital for the functionality and reliability of applications. One effective way to achieve this is through message brokers. RabbitMQ, an open-source message broker that implements the Advanced Message Queuing Protocol (AMQP), is a popular choice for building scalable and decoupled systems. This article will walk you through building simple applications in Go that communicate with each other via RabbitMQ. Prerequisites Before we dive into the code, make sure you have the following:

Deploying a RabbitMQ Cluster with Three Nodes on Kubernetes

Deploying a RabbitMQ cluster in a Kubernetes environment can significantly enhance the resilience and scalability of message-driven applications. In this article, we will walk you through the steps to deploy a RabbitMQ cluster composed of three nodes on Kubernetes using open-source tools. Prerequisites Before we begin, ensure you have the following prerequisites set up: A Kubernetes cluster (Minikube, GKE, EKS, AKS, etc.) kubectl command-line tool installed and configured to interact with your cluster.

Enabling Encrypted Communication for RabbitMQ

RabbitMQ is a powerful message broker software that facilitates communication between different components of a system, handling high-throughput use cases efficiently. One of the critical aspects of implementing RabbitMQ in production is ensuring that all communication is secure, particularly when messages travel over the network. This article focuses on enabling encrypted communication for RabbitMQ using TLS (Transport Layer Security), which is essential for protecting sensitive data and maintaining system integrity.

Connecting IKEA TRÅDFRI to an MQTT Broker

As the Internet of Things (IoT) begins to populate our homes with an increasing number of smart devices, many developers and hobbyists look for ways to integrate these devices into a cohesive environment. One such popular device is the IKEA TRÅDFRI lighting system, which offers wireless and user-friendly smart lighting solutions. In this article, I’ll walk you through the steps to connect IKEA TRÅDFRI lights to an MQTT broker, enabling you to control them programmatically and integrate them with other IoT devices.

Light Alternatives for Kubernetes as a Container Orchestrator

Kubernetes has established itself as the de facto standard for container orchestration, providing a robust platform for managing containerized applications in production.
