Sam Donche — NotesField notes on industrial digital architecturehttps://samdonche.com/notes/2026-09-22T12:00:00ZSam DoncheIgnition credentials belong in your secrets managerhttps://samdonche.com/notes/ignition-secrets/2026-09-22T12:00:00Z2026-09-22T12:00:00ZGateways still hold database passwords and script secrets. Why that breaks rotation and audits, and how a native secret-provider module resolves them from Vault, Azure, AWS or Google instead.Sam DonchePut your Ignition gateway on the same dashboards as everything elsehttps://samdonche.com/notes/ignition-observability/2026-09-22T12:00:00Z2026-09-22T12:00:00ZOpenTelemetry and Prometheus for Ignition 8.3: curated metrics, logs, and no wrapper.conf surgery.Sam DoncheTag history that stays fast when retention gets longhttps://samdonche.com/notes/ignition-historian/2026-09-22T12:00:00Z2026-09-22T12:00:00ZTimescaleDB-backed historian for Ignition 8.3. Aggregates in tens of milliseconds over hundreds of millions of rows.Sam DoncheStop scripting RabbitMQ inside Ignitionhttps://samdonche.com/notes/ignition-amqp/2026-09-22T12:00:00Z2026-09-22T12:00:00ZNamed AMQP broker connections as gateway config, Event Streams and system.amqp scripting. Replaces the client parked in getGlobals().Sam DonchePage the channel the crew actually watcheshttps://samdonche.com/notes/ignition-alarms/2026-09-22T12:00:00Z2026-09-22T12:00:00ZTeams, Slack and webhook alarm notification profiles for Ignition 8.3, with acknowledgement, retry, fallback and a delivery audit trail.Sam DoncheFourteen Perspective components the platform never shippedhttps://samdonche.com/notes/ignition-perspective/2026-09-22T12:00:00Z2026-09-22T12:00:00ZFree Apache-2.0 components: scheduling board, calendar, editable grid, pan-and-zoom, branching diagram, and the admin family Vision had.Sam DoncheYes, your Ignition gateway can run Doomhttps://samdonche.com/notes/ignition-doom/2026-09-22T12:00:00Z2026-09-22T12:00:00ZA free Perspective component that runs Doom inside SCADA. Tags fire the shotgun, alarms pause the marine. Industrially useless on purpose.Sam DoncheA dark Ignition Designer from one menu itemhttps://samdonche.com/notes/ignition-dark-mode/2026-09-22T12:00:00Z2026-09-22T12:00:00ZFree FlatLaf dark mode for the Ignition 8.3 Designer. Tools → Dark Mode, remembered between launches, open source on GitHub.Sam DoncheIgnition modules for the gaps the platform leaveshttps://samdonche.com/notes/ignition-modules/2026-09-22T12:00:00Z2026-09-22T12:00:00ZSecrets, RabbitMQ, Timescale, OpenTelemetry, alarm channels, Perspective UI, Designer dark mode, and Doom: Ignition 8.3 modules from Mustry, and where each one fits.Sam DoncheMQTT and Sparkplug B: why factories stopped pollinghttps://samdonche.com/notes/mqtt-sparkplug-b/2026-07-25T12:00:00Z2026-07-25T12:00:00ZPolling sets a ceiling on every factory data project. MQTT flips the direction; Sparkplug B adds the contract that makes it an architecture instead of topic soup.Sam DoncheMES vs SCADA vs historian: what actually goes wherehttps://samdonche.com/notes/mes-scada-vs-historian/2026-07-23T12:00:00Z2026-07-23T12:00:00ZThree layers of a factory's data stack, each answering a different question, and most stalled data projects got the layering wrong.Sam Donche
