Monitoring and Observability

Monitoring and observability are related concepts that both involve gathering and analyzing data to gain insights into the performance and behavior of systems. However, there are some key differences between monitoring and observability:

Source: Internet

  • Monitoring:Monitoring refers to the process of collecting and analyzing data about the state and performance of a system or application. It involves tracking predefined metrics, thresholds, and key performance indicators (KPIs) to assess the health, availability, and performance of the system. Monitoring typically focuses on specific metrics or events and provides a centralized view of the system’s current state.
  • Observability:Observability, on the other hand, refers to the ability to gain insights into the internal state of a system or application based on its outputs, behaviors, and events. It emphasizes the understanding of the system’s internal workings, making it easier to troubleshoot and diagnose issues. Observability is more focused on exploring and understanding the system’s behavior rather than predefined metrics.

In summary, monitoring focuses on predefined metrics and thresholds, providing a centralized view of system performance and triggering alerts when specific conditions are met. Observability, on the other hand, emphasizes understanding the system’s behavior and enables deep visibility into its internal workings, allowing for more exploratory analysis and troubleshooting. While monitoring is proactive and metric-driven, observability is more event-driven and focuses on understanding unknown unknowns and root cause analysis.
