Datadog – 11-Sept–23 (Day1) : Assignment 1

What is Observability and its advantage?

observability plays a critical role in maintaining the health, performance, and reliability of complex systems and applications, enabling organizations to respond effectively to evolving challenges and user needs based on the metrics / events / Logs and traces.

Difference between Observability Monitoring?

observability is a broader concept that focuses on understanding complex systems through a combination of data collection techniques, while monitoring is a specific subset of observability that concentrates on predefined metrics and alerts to proactively manage and respond to known issues. Both observability and monitoring are essential components of managing and maintaining modern computer systems and applications, with each serving distinct purposes within the realm of system management and troubleshooting.

What is Datadog?

cloud-based monitoring and analytics platform that provides comprehensive observability and monitoring solutions for cloud-scale applications, infrastructure, and services.

What is Datadog Agent and How it works?

Datadog Agent is a lightweight software component that you install on your infrastructure to collect and transmit performance and monitoring data to Datadog's cloud-based platform. It is a critical part of Datadog's monitoring and observability solution, enabling users to gain insights into the health and performance of their systems, troubleshoot issues, and set up proactive alerts for problem detection and resolution. The Agent's extensibility and integrations make it a versatile tool for monitoring a wide range of environments and technologies.

Component of Datadog Agent and short intro for each

Datadog Agent consists of several key components.

  1. Collector - is responsible for collecting various types of data, including system-level metrics (CPU, memory, disk, network), application-level metrics (e.g., request rates, response times), and custom metrics. It also collects logs and traces if configured to do so.

  2. DogStatsD - DogStatsD is a built-in implementation of the StatsD protocol provided by Datadog. It allows you to send custom application metrics to Datadog, which can be useful for tracking application-specific performance and business metrics.

  3. Forwarder - Forwarder is used to forward all event / metrics recieved from DogStatsD
