George Kobar, a community advocate for Capgemini, shared information on observability at a Meetup for New Application Development. The document defines observability as the combination of monitoring, metrics, and logging. It presents a typical observability stack that collects data from various sources to provide visibility for development, operations, and business teams through tools that analyze application performance, uptime, logs, metrics, and business KPIs. The stack advocates an elastic approach to storing all operational data together in Elasticsearch for unified access and analysis.
