Start with the failure at monitor.go:267 and read the roachtest README for investigation context. Inspect the artifacts and logs under /artifacts/cdc/frontier-persistence-benchmark/interval=10m/tables=10000/ranges=1/run_1, then use the linked Grafana view to determine why max latency exceeded 2m. Done means the cause is identified and the benchmark no longer fails for this condition.
