Introducing Workers Observability: logs, metrics, and queries – all in one place

Cloudflare has announced a new section called Workers Observability in their Cloudflare Dashboard, which allows users to query detailed log events across all Workers in their account. This feature provides deeper insights into system performance and can be used to answer questions such as "why" certain issues are occurring. The Query Builder tool enables users to construct structured queries to explore logs, extract metrics from logs, create graphical and tabular visualizations, and save queries for faster future investigations. Workers Observability also includes features such as CPU time and wall time monitoring, revamped Workers metrics, an Invocations view, and a Workers Observability API that allows users to programmatically retrieve their telemetry data. To use the feature, users need to enable Workers Logs in their Workers' settings or add a configuration to their wrangler file.
