### Search before asking - [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version 2.1.7 ### What's Wrong? When deploying Doris BE on machines with NVME disks, I/O metrics like `doris_be_max_disk_io_util_percent ` or `doris_be_disk_io_time_ms` are all 0's. After debugging, it is found that `device` labels in the metrics are like `nvmeXnYp`. ``` $ curl http://localhost:8040/metrics | grep "doris_be_disk_io_time_ms" # TYPE doris_be_disk_io_time_ms counter doris_be_disk_io_time_ms{device="nvme1n1p"} 0 doris_be_disk_io_time_ms{device="nvme5n1p"} 0 doris_be_disk_io_time_ms{device="nvme0n1p"} 0 doris_be_disk_io_time_ms{device="nvme3n1p"} 0 doris_be_disk_io_time_ms{device="nvme6n1p"} 0 doris_be_disk_io_time_ms{device="nvme7n1p"} 0 doris_be_disk_io_time_ms{device="nvme4n1p"} 0 doris_be_disk_io_time_ms{device="nvme2n1p"} 0 ``` while the real device names are like `nvmeXnY` or `nvmeXnYpZ`. ``` $ cat /proc/partitions major minor #blocks name 8 0 468320256 sda 8 1 488264 sda1 8 2 467830784 sda2 253 0 20971520 dm-0 253 1 12582912 dm-1 253 2 434274304 dm-2 259 0 1875374424 nvme0n1 259 1 1875373056 nvme0n1p1 259 2 1875374424 nvme1n1 259 3 1875373056 nvme1n1p1 259 4 1875374424 nvme7n1 259 5 1875373056 nvme7n1p1 259 6 1875374424 nvme6n1 259 7 1875373056 nvme6n1p1 259 8 1875374424 nvme5n1 259 12 1875373056 nvme5n1p1 259 9 1875374424 nvme4n1 259 13 1875373056 nvme4n1p1 259 10 1875374424 nvme3n1 259 14 1875373056 nvme3n1p1 259 11 1875374424 nvme2n1 259 15 1875373056 nvme2n1p1 ``` ### What You Expected? expose I/O metrics correctly for NVME devices ### How to Reproduce? _No response_ ### Anything Else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
