Here's a scenario every engineering team has experienced: a third-party service goes down, and your monitoring tool fires alerts for every endpoint that touches it.
Your payment API? Alert. Your billing webhook? Alert. Your subscription service? Alert. Your checkout page health check? Alert.
Four alerts, one root cause. Multiply that by a team of 5 with Slack notifications, and you've got 20 messages drowning out actual signal.
The Problem With Independent Monitors
Traditional uptime monitoring treats each check as independent. Monitor A checks your auth endpoint. Monitor B checks your payment endpoint. Monitor C checks your webhook receiver. They don't know about each other, and they definitely don't know that all three depend on Stripe.
When Stripe has an incident:
- Monitor A detects 500 errors → alerts
- Monitor B detects timeouts → alerts
- Monitor C detects failures → alerts
Your team scrambles. Is it a deployment issue? Infrastructure? DNS? Someone eventually checks Stripe's status page and realizes it's them. 15 minutes wasted.
Resource Group Alerts
DevHelm's resource groups solve this by letting you declare dependencies explicitly:
resource_groups:
- name: payment-flow
monitors: [checkout-api, billing-webhook, subscription-service]
dependencies: [stripe, aws-us-east-1]
When Stripe degrades, DevHelm correlates the timing of your monitor failures with Stripe's status change. Instead of 3 separate alerts, you get one:
Resource Group Alert: payment-flow Upstream dependency degraded: Stripe Affected monitors: checkout-api, billing-webhook, subscription-service
One notification. Root cause identified. Your team knows immediately that it's not their code.
Getting Started
DevHelm tracks 80+ external services out of the box. To set up dependency tracking:
- Create monitors for your endpoints
- Group related monitors into resource groups
- Add external dependencies to each group
- Get correlated alerts instead of noise
The free tier includes 10 external service dependencies and 3 resource groups. Try it free.
