MEDIUM: Prometheus scrapes 14 targets but only Go/Java services expose metrics

[Senthil455]

Summary

Prometheus is configured to scrape all 14 service targets at /metrics, but only Go and Java services expose a metrics endpoint. Node.js (Express) and Python (FastAPI) scrapes return 404.

Affected File

prometheus.yml:13-81

Impact

• Half of Prometheus scrape targets return 404 errors
• No metrics collected from Python and Node.js services
• Dashboards for these services show no data
• Alert rules referencing http_requests_total are never triggered

Fixed in PR #83 - #83

All Node.js (Express) and Python (FastAPI) services now expose a valid /metrics\ endpoint with consistent \�tlas_http_*\ metric names. Go services were also instrumented for consistency. The \HighErrorRate\ alert rule now references \�tlas_http_requests_total\ which is actually emitted by the services.

Fixed by PR #83 - all Node.js, Python, and Go services now expose /metrics endpoints with atlas_http_* metric names.
