Modern observability (o11y) offers a more comprehensive understanding of system health and performance compared to traditional monitoring methods. It focuses on collecting and analyzing logs, traces, and events in real-time, providing proactive insights into system behavior and potential issues. By adopting modern o11y, businesses can enhance productivity, reduce costs, and mitigate risks, fostering operational excellence. The shift to o11y requires a new perspective, prioritizing user experience and measuring what matters - the experience of people using the service. To implement modern o11y, organizations should add observability capabilities, integrate their tools, and simplify their inputs. This involves identifying missing capabilities, installing and training on new solutions, integrating data from existing monitoring tools, and removing redundant inputs to achieve peak observability.
