Jira issue: CRDB-65594

Start with pkg/cmd/roachtest/README.md and the monitor_failure report for the ycsb/C/nodes=3/cpu=32/mvcc-range-keys=global run. Inspect the linked TeamCity artifacts, Grafana dashboard, and Datadog logs to determine why the monitor user task called t.Fatal(). Done means identifying the failure cause and validating the appropriate fix or test change with a passing roachtest run.
