You can view the read throughput of files on each brick. If brick name is not specified, then the metrics of all the bricks belonging to that volume will be displayed. The output will be the read throughput.
This command will initiate a read for the specified count and block size and measures the corresponding throughput directly on the back-end export (bypassing glusterFS processes).
To view list of read performance on each brick
- View list of read performance on each brick using the following command:
# gluster volume topVOLNAMEread-perf [bsblk-sizecountcount] [nfs | brickBRICK-NAME] [list-cntcnt]For example, to view read performance on brickserver:/export/of test-volume, 256 block size of count 1, and list count 10:# gluster volume top test-volume read-perf bs 256 count 1 brick server:/export/ list-cnt 10 Brick: server:/export/dir1 256 bytes (256 B) copied, Throughput: 4.1 MB/s ==========Read throughput file stats======== read filename Time through put(MBp s) 2912.00 /clients/client0/~dmtmp/PWRPNT/ -2012-05-09 TRIDOTS.POT 15:38:36.896486 2570.00 /clients/client0/~dmtmp/PWRPNT/ -2012-05-09 PCBENCHM.PPT 15:38:39.815310 2383.00 /clients/client2/~dmtmp/SEED/ -2012-05-09 MEDIUM.FIL 15:52:53.631499 2340.00 /clients/client0/~dmtmp/SEED/ -2012-05-09 MEDIUM.FIL 15:38:36.926198 2299.00 /clients/client0/~dmtmp/SEED/ -2012-05-09 LARGE.FIL 15:38:36.930445 2259.00 /clients/client0/~dmtmp/PARADOX/ -2012-05-09 COURSES.X04 15:38:40.549919 2221.00 /clients/client9/~dmtmp/PARADOX/ -2012-05-09 STUDENTS.VAL 15:52:53.298766 2221.00 /clients/client8/~dmtmp/PARADOX/ -2012-05-09 COURSES.DB 15:39:11.776780 2184.00 /clients/client3/~dmtmp/SEED/ -2012-05-09 MEDIUM.FIL 15:39:10.251764 2184.00 /clients/client5/~dmtmp/WORD/ -2012-05-09 BASEMACH.DOC 15:39:09.336572
