The Prometheus documentation (https://docs.ceph.com/en/latest/mgr/prometheus/) mentions the node exporter metric "node_disk_bytes_written". This metric name is no longer available since node exporter version 0.16.0 (https://github.com/prometheus/node_exporter/releases/tag/v0.16.0). It has been renamed to "node_disk_written_bytes_total" (see https://github.com/prometheus/node_exporter/blob/v0.16.0/docs/example-16-compatibility-rules.yml for the full list of renames). The documentation is still using "node_disk_bytes_written" and needs to be updated.
