Monitoring & Observability Glossary

AWS monitoring service that collects and tracks metrics, logs, and events from your applications and infrastructure. Like a security camera system that watches everything and alerts you when something unusual happens.

Open-source monitoring and alerting toolkit for collecting and querying metrics. Like having a health monitoring system for your applications that tracks everything and alerts you to problems.

Open-source platform for monitoring and observability with customizable dashboards. Like having a mission control center with screens showing the health of all your systems.

AWS service for monitoring, storing, and accessing log files from EC2 instances and other AWS services. Like having a centralized filing system for all system messages and errors.

Azure service for collecting and analyzing telemetry data from cloud and on-premises environments. Like having a comprehensive health monitoring system for all your technology infrastructure.

Azure service for collecting and analyzing log data from various sources. Like having a detective that can analyze clues from different crime scenes to solve complex cases.

Google Cloud's centralized logging service that collects, stores, and analyzes logs from all your applications and infrastructure. Like having a detailed diary that automatically records everything happening across your cloud environment.

Continuous tracking and analysis of application performance metrics to identify bottlenecks, errors, and optimization opportunities.

Collecting and storing log data from multiple applications and systems in one central location for easier searching, monitoring, and analysis.

Ability to understand what's happening inside a system by examining its outputs like logs, metrics, and traces. Like having security cameras, temperature sensors, and activity logs to understand everything happening in a building.

Application Performance Monitoring - tools that track how well your application performs and where bottlenecks occur. Like having a fitness tracker for your software that shows which parts are working hard and which are slowing down.

Recording events and activities that happen in your application for debugging and monitoring. Like keeping a detailed diary of everything your application does so you can review it later.

Four key metrics for monitoring distributed systems: latency, traffic, errors, and saturation. Like the vital signs doctors check to assess patient health.

A technique for tracking a single request as it travels through many different services in a cloud application. Like following a package through the postal system — you can see every stop it made, how long it spent at each location, and where any delays occurred.
