I've looked at `monitoring/grafana/dashboards/rbd-overview.json` and `monitoring/grafana/dashboards/rbd-overview.json` and in both the Y axis unit appears to be set to `ns` in both.
But since the pane titles here are "Average Latency", I suspect that those aren't what you're talking about.
`src/pybind/mgr/prometheus/module.py` however does describe these metrics in terms of ms so I suspect that's what you ran into.
