Analogy
An alerting system is like a home alarm that senses a break‑in and notifies you and the security company immediately.
Definition
An infrastructure that detects predefined blockchain events or anomalies and delivers notifications through channels like email, SMS, or chatops for operational and security teams.
Key Points Intro
Alerting systems transform raw blockchain data and logs into actionable notifications.
Key Points
Event subscriptions: Listen to on‑chain logs or metrics streams.
Threshold rules: Trigger alerts when values exceed defined limits.
Notification channels: Support email, SMS, Slack, PagerDuty, etc.
Escalation policies: Define retries and on‑call rotations.
Example
Technical Deep Dive
Implement Web3 subscriptions via WebSocket RPC to capture events. Pipe data into time-series DB (Prometheus) and define alert rules in Alertmanager. Integrate with notification adapters to push messages via webhook to OpsGenie or Microsoft Teams. Ensure high-availability via clustering and message queue buffering.
Security Warning
Unsecured alert channels can leak sensitive operational data. Use encrypted transports and authenticated webhooks.
Caveat
High-frequency alerts may incur messaging costs and overwhelm teams; balance sensitivity with noise reduction.
