Self-Healing Multi-Model Gateway & Zero-Token Cron Watchdog
“Monitor 24/7 Multi-Agent Infrastructure Across 1.55B+ Tokens at $0.00 Idle LLM Cost with Deterministic Cron Watchdogs.”
Zero-token infrastructure watchdog (Hermes no_agent=True cron pattern) that monitors multi-model proxy lanes (LiteLLM, Claude, Gemini, Codex), verifies SQLite WAL session store integrity across 1.55B+ tokens, and alerts operators only on state transitions.
CLAIM: $0.00 idle token cost for 24/7 multi-agent health monitoring across 1.55B+ production tokens and 743+ sessions. PROOF: Deterministic state-transition watchdog (skills/multi-agent-gateway-watchdog/gateway_health_watchdog.py --selftest PASS) runs with no_agent=True and suppresses duplicate alerts.
How do we monitor our AI agents and database health 24/7 without burning thousands of dollars in API tokens on idle health checks?
Aria replaces token-burning LLM heartbeat prompts with a deterministic `no_agent=True` Python watchdog that probes model proxies, OAuth tokens, and SQLite FTS5 session databases every 5 minutes for $0.00—emitting zero output when healthy and firing instant Telegram alerts only on state transitions.
Production Stack
Proven Production Guarantees
- Saves $1,200+/month in wasted LLM heartbeat tokens by running 288 daily health checks per profile via zero-token Python state machines.
- Eliminates alert fatigue with strict state-transition deduplication: notifies operators only on `UP → DEGRADED` or `DEGRADED → RECOVERED` events.
- Continuously verifies LiteLLM/AGY proxy ports, OAuth credential freshness, and SQLite WAL journal integrity across 1.55B+ tokens of session history.
Implementation & Verification Runbook
Execute the state-transition watchdog self-test to verify zero-byte stdout on healthy ticks and structured alerts on lane degradation.
