In the beginning, IT teams utilized Application Performance Monitoring (APM) and Network Performance Monitoring (NPM) as tools to oversee and diagnose problems at the application and infrastructure levels. However, with the advent of contemporary development practices, the introduction of numerous distributed components made it difficult for APM and NPM solutions to offer complete visibility across the entire system.
As a result, observability emerged as the logical successor to APM and NPM, owing to its capacity to provide comprehensive visibility within a distributed IT system. Through observability, businesses can take proactive measures to resolve production-level issues.
