📄️ Overview
Telemetry is the process of collecting, transmitting, and analyzing data from remote or inaccessible points to monitor the performance, health, and usage of systems. In the context of server applications like Stalwart Mail Server, telemetry involves gathering various metrics that provide insights into the server's operation, resource usage, and overall health. This information is crucial for system administrators and developers to ensure the server runs efficiently, identify and troubleshoot issues, and optimize performance.
📄️ OpenTelemetry
OpenTelemetry is an open-source observability framework designed to provide standardized methods for collecting, processing, and exporting telemetry data such as metrics, logs, and traces. OpenTelemetry aims to simplify the process of instrumenting applications to monitor their performance and behavior across distributed systems. It offers a comprehensive set of APIs, libraries, agents, and instrumentation tools, facilitating the collection of telemetry data from various programming languages and platforms.
📄️ Prometheus
Prometheus is an open-source systems monitoring and alerting toolkit designed for reliability and scalability. Developed by SoundCloud in 2012 and now part of the Cloud Native Computing Foundation, Prometheus has become one of the most popular monitoring solutions in the industry. It is known for its powerful data model, flexible query language (PromQL), and the ability to collect time-series data, making it ideal for monitoring dynamic and highly complex environments.
