Overview

Fontana includes full observability with every workspace deployment: operational telemetry for day-to-day platform operations, and a tamper-evident security audit trail for compliance evidence. Logs, metrics, dashboards, service health checks, and append-only audit history are built into the stack and provisioned with your environment. You do not need to install, license, or configure external telemetry or log aggregation products to gain visibility across your tenant.

On the Flow canvas, each node also exposes run status, row counts, and data-quality audit items as a workflow executes. Those signals are workflow provenance on the file store. See Data lineage and Storage and processing.

Topics

Section titled “Topics”
  • Operational telemetry - Grafana and Loki logs, Gatus health checks, otel collector, and what Fontana collects for SRE and incident response
  • Security audit (WORM) - append-only ImmuDB ledger, who emits security events, and how it differs from workflow lineage and chat audit

Planes at a glance

Section titled “Planes at a glance”
Plane System of record Typical use
Operational telemetry Platform Grafana + Loki (search and dashboards) SRE dashboards, incident response, browser errors, pod logs, service health
Security audit (WORM) ImmuDB per workspace Compliance evidence, tamper-evident append-only platform activity
Workflow lineage and port audit Workflow file store (not ImmuDB) How a cell was computed; validation and edit context on a run

Platform Loki may mirror security audit events for faster search. ImmuDB holds the compliance system of record. See Data retention for retention boundaries across operational logs, ImmuDB, and the workflow file store.
