# 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 unhealthy machines
import express from 'express';
const app = express();
app.get('/health', async (req, res) => {
const checks = {
database: await checkPostgres(),
redis: await checkRedis(),
memory: process.memoryUsage().heapUsed < 500 * 1024 * 1024, // < 500MB
};
const healthy = Object.values(checks).every(Boolean);
res.status(healthy ? 200 : 503).json({
status: healthy ? 'healthy' : 'unhealthy',
region: process.env.FLY_REGION,
machine: process.env.FLY_MACHINE_ID,
checks,
});
});
```
### Step 3: Structured Log Processing
```bash
# Stream logs and process with jq
fly logs -a my-app --json | jq -c 'select(.level == "error")' | while read -r line; do
echo "$line" >> errors.jsonl
# Send to Slack, PagerDuty, etc.
done
# Search recent logs for specific patterns
fly logs -a my-app --no-tail | grep -i "error\|crash\|oom"
```
### Step 4: Deployment Event Notifications
```bash
# Post-deploy notification in CI
fly deploy -a my-app && \
curl -X POST "$SLACK_WEBHOOK_URL" \
-H "Content-Type: application/json" \
-d "{\"text\": \"Deployed my-app to Fly.io. Status: $(fly status -a my-app --json | jq -r '.Status')\"}"
```
