"The Well-Monitored Service"

Pentacles · Infrastructure

Upright +2

Dashboards that tell you what is happening. Alerts that fire before users notice. p99 latency tracked, error budgets defined, SLOs published and reviewed. The Nine of Pentacles is the service you can trust because someone built the observability to prove it deserves trust.

Reversed -1

Four hundred alerts, all of them firing, none of them actionable. The on-call engineer has muted the PagerDuty channel and is checking manually every hour. The Nine of Pentacles reversed is monitoring that exists to perform diligence rather than provide it.
