# HELP ev_metrics_submission_duration_seconds da blob submission duration from block creation to da availability
# TYPE ev_metrics_submission_duration_seconds summary
ev_metrics_submission_duration_seconds{chain_id="testnet",type="header",quantile="0.5"} 104.37355353
ev_metrics_submission_duration_seconds{chain_id="testnet",type="header",quantile="0.9"} 196.37355353
ev_metrics_submission_duration_seconds{chain_id="testnet",type="header",quantile="0.95"} 198.37355353
ev_metrics_submission_duration_seconds{chain_id="testnet",type="header",quantile="0.99"} 199.37355353
ev_metrics_submission_duration_seconds_sum{chain_id="testnet",type="header"} 31758.898120131016
ev_metrics_submission_duration_seconds_count{chain_id="testnet",type="header"} 309

The values are not very good right now, but there is an issue with DA submission ATM which will hopefully help once fixed, and there may be something else to investigate on the ev-node side.

unrelated change but I think the tag should have the prefix v to match the git tag directly.
