EventBridge says scheduled. Your data says otherwise.
Verify each Lambda run with a completion ping and alert on misses.
Serverless schedules can look healthy while permissions, timeouts, or logic regressions break outcomes.
- CloudWatch noise masks business-critical failures
- Missed schedules create data gaps
- No app-level completion guarantee
Step 1
Add success/fail pings in Lambda handler
Step 2
Set expected interval to your EventBridge cadence
Step 3
Use alerts to respond before downstream consumers fail
Node Lambda handler
export const handler = async () => {
try {
await runTask();
await fetch('https://silentfail.dev/api/ping/YOUR_TOKEN/success', { method: 'POST' });
} catch (error) {
await fetch('https://silentfail.dev/api/ping/YOUR_TOKEN/fail', { method: 'POST' });
throw error;
}
};Built for developers. No credit card. Free for 1 check.
Lightweight ping API for cron, queue, and serverless runtimes.
Alerting channels: email + Slack, with event history for audits.
Public status available at /status.
Do I need AWS integration credentials?
No, HTTP ping endpoints are enough.
Can I track timeouts?
Yes, send fail before rethrowing terminal exceptions.
Does this support Python Lambdas?
Yes, use any language that can make HTTPS calls.
Can I monitor many schedules?
Yes, one check per schedule keeps clarity.
Can I use this in multi-account setups?
Yes, endpoints are globally reachable over HTTPS.
