# Fly.io Events & Monitoring ## Overview Fly.io does not have traditional webhooks. Instead, monitor machine state changes via the Machines API, process structured logs via `fly logs`, and use health check endpoints for automated responses. ## Instructions ### Step 1: Poll Machine State Changes ```typescript // Monitor machine state transitions via Machines API async function watchMachines(appName: string, callback: (event: MachineEvent) => void) { const client = new FlyClient(appName, process.env.FLY_API_TOKEN!); const stateCache = new Map<string, string>(); setInterval(async () => { const machines = await client.listMachines(); for (const m of machines) { const prev = stateCache.get(m.id); if (prev && prev !== m.state) { callback({ machineId: m.id, region: m.region, previousState: prev, currentState: m.state, timestamp: new Date(), }); } stateCache.set(m.id, m.state); } }, 10_000); // Check every 10 seconds } interface MachineEvent { machineId: string; region: string; previousState: string; currentState: string; timestamp: Date; } ``` ### Step 2: Health Check Event Handler ```typescript // Implement health check that reports machine health // Fly.io uses this to auto-restart unhe

Stream logs and process with jq
fly logs -a my-app --json | jq -c 'select(.level == "error")' | while read -r line; do
echo "$line" >> errors.jsonl
done
Search recent logs for specific patterns
fly logs -a my-app --no-tail | grep -i "error\|crash\|oom"
Post-deploy notification in CI
fly deploy -a my-app && \
curl -X POST "$SLACK_WEBHOOK_URL" \
