@gquintard lets tweak the heatmaps here. As discussed, we need otel 2.0 with ttfb/ttlb support out before merge...

Dashboards contain insights on:

  • TTFB (Avg / p95): visualize client ↔ backend first-byte latency
  • TTLB (Avg / p95): show total end-to-end response times
  • Transfer Size (Bits/sec / p95): display traffic throughput and 95th-percentile payload sizes

any chance you can make the changes a bit more targeted? This PR changes a bunch of unrelated line (I think)

Good point! this PR focus only on the dashboard part (varnish_metrics.json) changes. Unfortunately, the dashboard is self-contained inside of the provisioning folder. Not sure other way I can proposed changes and validate it here? This PR will make sense only when we have the otel 2.0 out and supported here. Then; we merge this one and the new metrics/dashboard will work just fine. But... I'm open for thoughts, ofc...
