Dead period during approx. 5 minutes after deployment

[Rindrics]

I can't receive metrics generated during approximately 5 minutes after deployment.

• configuration
  • Next.js v14 with instrumentationHook enabled
  • call registeroTel() inside register() in instrumentation.ts
• condition
  • calling server action instrumented with counter metrics
• what I wanted
  • receive "ALL" the metrics generated by each request
• what I got
  • cannot receive metrics generated during approximately 5 minutes after deployment
  • can receive only after the period above
• how to reproduce
  • my code here)

I'm wondering if this is related to "cold start" of Vercel env because metrics from local env is received immediately.
Does anyone have any ideas on how to solve or understand these phenomenon?
