Hi,
I'd like to monitor the IOPS on the Lustre OSTs. I have stats like this: [root@xxx04 ~]# lctl get_param obdfilter.xxx-OST0000.stats obdfilter.xxx-OST0000.stats= snapshot_time 348287.096066602 secs.nsecs start_time 0.000000000 secs.nsecs elapsed_time 348287.096066602 secs.nsecs read_bytes 3075 samples [bytes] 0 1134592 2891776 2568826650624 write_bytes 1312266 samples [bytes] 1 4194304 5424381521966 4303559271585613940 read 3075 samples [usecs] 0 489 31040 3417458 write 1312266 samples [usecs] 1 1630262 6193336309 3686004830368845 setattr 20373 samples [usecs] 1 61 133314 1090612 punch 4600 samples [usecs] 3 65 51155 732959 sync 4 samples [usecs] 443 997 2853 2250847 destroy 30777 samples [usecs] 11 42634 20978596 33571893182 create 993 samples [usecs] 1 29995 534579 1518818913 statfs 135519 samples [usecs] 0 24 610182 4231650 get_info 108 samples [usecs] 1 3092 6218 17971060 set_info 10047 samples [usecs] 1 22 83418 770166 >From the docs https://wiki.lustre.org/Lustre_Monitoring_and_Statistics_Guide I >see: """ For read_bytes and write_bytes: First number = number of times (samples) the OST has handled a read or write. """ I guess this can be considered as OST IOPS? Regards, Marco Passerini
