Grafana Dashboard Setup

Configure Grafana to use Prometheus as a datasource and build dashboard panels for CPU, memory, and request visibility in the JLT-Lane sandbox environment.

Open Grafana

http://localhost:3000

Typical local login:

admin / admin

Add Prometheus datasource

Use the Prometheus service URL inside Docker:

http://prometheus:9090

Example queries

process_cpu_seconds_total
process_resident_memory_bytes
nodejs_active_handles
auth_service_http_requests_total

Suggested dashboard panels

  • CPU usage
  • Memory usage
  • HTTP request volume
  • Runtime handle/activity visibility

Validation

Run queries directly in Grafana Explore first. If results appear there, then add them as dashboard panels and save the dashboard.

Success criteria

  • Prometheus datasource saves successfully
  • Queries return live data
  • Dashboard panels render without errors
