ObservabilityCON 2020 focused on Prometheus and its evolving role in monitoring applications and services, highlighting new tools and features aimed at improving alerting, debugging, and scalability. Grafana Labs, with six of the 24 Prometheus maintainers, introduced updates like backfilling support and the Grafana Agent, which facilitates data queries from multiple Prometheus servers through a central store. They also showcased enhancements in Grafana Cloud, such as a streamlined interface for managing alerts and a synthetic monitoring plugin to debug user experience. The event featured discussions on using Prometheus in enterprise environments with Grafana Metrics Enterprise, continuous profiling with ConProf, and building observability infrastructure with Istio and Jaeger. Additionally, the importance of continuous monitoring was emphasized through case studies like Gofers in India, which leverages a model built on Loki, Prometheus, and Grafana to enhance operational efficiency and business health.
