Observability and monitoring are the two different types of DevOps measurement contributing to continuous delivery. These two are often used interchangeably, but there are key differences between them that separate them from each other.
Observability is defined as the ability to understand a system's internal state by analyzing the data generated by the system, such as — logs, metrics, and traces. Monitoring is closely related to Observability. In general, monitoring is classified as the collection and analysis of data that are pulled from IT systems. By analyzing the information about the application’s usage patterns, monitoring helps IT teams detect vulnerabilities beforehand and come up with an appropriate solution.
