Infrastructure health checks use lightweight queries like SELECT 1 or GET/SET with short timeouts to monitor dependencies without impacting production traffic. They use separate health-check connections and cache results for 30-60 seconds to prevent stampedes and reduce load.

The best way to detect degraded infrastructure is through parallel health checks that report dependency states as UP, DEGRADED, or DOWN. By measuring response times and using lightweight queries, you can identify performance degradation before a complete failure occurs.

You can run parallel health checks on external APIs by configuring the service to execute checks simultaneously with short timeouts. This approach quickly identifies unresponsive dependencies and reports their health state while caching results to prevent request stampedes.

Yes, you need separate health-check connections to avoid exhausting production database pools. Using dedicated connections ensures that lightweight monitoring queries do not interfere with or block active production traffic during health assessments.

Caching infrastructure health check results for 30-60 seconds prevents request stampedes and reduces load on dependencies. This caching mechanism ensures that frequent health assessments do not negatively impact production traffic or overwhelm external APIs and databases.

Yes, you can monitor file system health alongside databases, caches, and external APIs in production. The service performs parallel, lightweight checks across all these dependencies and reports their health state as UP, DEGRADED, or DOWN with per-dependency details.
