# Follow a signal through to an investigation.

Connect endpoint checks with DNS history and server resources.

More space for focused work

A practical starting point

## Turn a failure signal into a focused investigation.

A useful check should tell you what it expects, where it runs and what to inspect when it fails. Monitor safe health endpoints, keep a record of intended DNS configuration and review server resources alongside logs. This provides context without treating monitoring as a replacement for application observability.

### A situation you might recognize

An API begins returning errors shortly after a deployment. Start with the failed response, compare the first failure with the release window, then inspect resource trends and upstream dependencies. A simultaneous DNS change is another clue to verify, not proof of the cause.

### Your starting checklist
- Expected HTTP responses for safe application health endpoints
- Heartbeats tied to meaningful scheduled-job completion
- Linux CPU, memory, disk and network signals
- DNS history and a clear alert destination for the service ownerExplore the platform →

## Make it a routine.

Before deployment, review the current baseline. After deployment, check availability and loading performance. During triage, preserve the time window, compare independent signals and document the evidence behind any remediation or rollback decision.

### Keep the evidence in context.

Availability checks, resource history and AI suggestions support investigation. They do not provide distributed tracing, confirm a root cause or automatically repair infrastructure.Read practical guides →
