Done in ad334cb — bucket array updated to match the refined values in tronprotocol/java-tron#6730. Also note the dashboard panel was already realigned to the new boundaries in f9325c7 earlier in this PR.

- `tron:block_transaction_count_count`: Count of observed blocks

Check the usage from dashboard panel (enter edit mode), or by searching in [grafana_dashboard_tron_server.json](grafana_dashboard/grafana_dashboard_tron_server.json).
