Overview

How the system itself is monitored and managed, organized around the FCAPS model: Fault, Configuration, Accounting, Performance, and Security.

Topics

• Service Monitoring — runtime observability for Arda’s own services.
• Sentry Observability — end-to-end Sentry instrumentation: capture topology, error classification, release health, PII scrubbing, trace propagation, agent + SDK coexistence.
• Postmark Service — the third-party email service Arda consumes; account inventory, API observations, and the operator runbook.
• Security: Secrets Vault — 1Password as the system of record for credentials.
