This “operations database” (OpsDB) accumulates status and metrics from all the servers, applications, batch jobs, and feeds that make up the extended system. It provides the “single pane of glass” that can present business-oriented metrics in the dashboard, system statistics, and, best of all, the correlations between them. Whereas logging provides visibility into a single application, the broader view of the OpsDb unifies status and metrics reporting across the entire system.
