Running the Data EngineWhat the engine does each pass, how work is partitioned across engines, and the properties that control it.Monitoring Infohub and Its HealthThe Monitor in Flow Config, what "caught up" looks like, and building estate-wide health visibility for many instances.Engine Performance and TuningFind the bottleneck before changing anything — source latency, database, model shape, and the concurrency settings.Database MaintenanceIndexes, statistics, growth, and retention — the routine care an Infohub database needs to stay fast.The Maintenance WindowInfohub's built-in nightly maintenance — exactly what runs, in what order, the properties that govern it, and what to do when it fails.Backup and RecoveryOne database holds everything — plus the licence surprise that catches every restore to a new server.Backfilling and RecalculationWhat backfill actually does, when it is the right tool, and the behaviours that surprise people — evaluation before the date, manual calendars, and events.Diagnosing Missing DataA procedure that finds the cause quickly — work down the chain from the measure to the source, in order.Diagnosing Stuck or Faulted MeasuresA measure that has stopped advancing while others progress — the distinct causes, and how to tell them apart.Reading Infohub LogsThree places Infohub records what happened — the Windows event log, the in-database engine log, and CLI log files.Common Problems and FixesThe symptoms that come up most often, with the cause and the fix — start here before working through a full diagnosis.Error Message IndexThe exact error text Infohub and the platform beneath it produce, what raises each one, and what to do — indexed by the words on your screen.Users, Groups, and AccessInfohub's group-based security model — users, per-object scoping, Windows accounts, and the honest limits (view-only, AD groups, multi-domain).HTTPS and CertificatesTLS on Bootstrap and Flow Server — configuration, the certificate-renewal failure everyone hits, and the deploy error that mentions HTTPS ports.Server Keys and Machine AccessHow a script, dashboard or integration authenticates to Flow Server without a person signing in — and how long its token lasts.Host Configuration FilesWhat lives in each component's appsettings.json — and why there is so little in it.Querying Infohub from SQLThe supported read surface — which views are the contract, which are deprecated, and how not to be broken by an upgrade.Instance Lifecycle AdministrationRenaming, moving, mirroring, and retiring an instance — plus the honest answer on rolling a model back.
