31 sentinels. 5 tiers. Always probing.

The sentinel grid is BrainstormMSP's continuous observability layer. Sentinels probe vendor APIs, AI services, intelligence sources, edge fleet endpoints, and platform internals. Aggregate health publishes to /status; per-tenant detail surfaces inside MSP.

Tier 1 · Platform

7 platform sentinels.

• API health
• Database latency
• NATS message lag
• ALB target health
• ECS task health
• Keycloak auth path
• Signing-key envelope availability

Tier 2 · Vendor

8 vendor sentinels.

• RMM (ConnectWise, Datto)
• EDR (CrowdStrike, SentinelOne)
• IDP (Okta, Azure AD)
• Ticketing (Jira, ServiceNow)
  Each probes connector health + sample-call latency.

Tier 3 · AI

6 AI sentinels.

• Anthropic
• OpenAI
• Google
• xAI
• Perplexity
• Mistral
  Hourly probes of latency + correctness on a known-answer benchmark.

Tier 4 · Intelligence

5 intelligence sentinels.

• Threat intelligence feeds
• CVE bulletins
• Dark-web monitors
• Breach databases
• Ransomware leak sites.

Tier 5 · Edge Fleet

5 fleet sentinels.

• Endpoint check-in rates
• Agent heartbeat distribution
• OS update lag
• EDR coverage
• Configuration drift.
