Hi:<br><br>How do I calculate total IOPS done by different FIO threads/jobs?<br><br>Following is output from FIO (with two threads)...<br><br>Each thread shows &quot;bw&quot; and &quot;iops&quot; numbers. Towards the end of output log, there is &quot;aggrb&quot; which is sum of individual &quot;bw&quot; of threads, but &quot;io&quot; field (3 line from the bottom of output below) doesn&#39;t seem to be sum of individual thread iops....<br>
<br>For example, Thread_1 has bw: 15k iops: 29366<br>Thread_2 has bw: 15k iops: 29445 <br> But, the summary towards the end (third line from bottom of output), says &quot;io=1,723MiB, aggrb=30,105KiB/s&quot;.<br><br>In this aggrb is good but io doesn&#39;t match up (it should be 58781) ! Can someone please educate what am I missing?<br>
<br>Thanks a lot!<br><br>================================== FIO Output =========================================<br>[root@localhost fio-1.24]# ./1.sh<br>job1: (g=0): rw=read, bs=512-512/512-512, ioengine=libaio, iodepth=4000<br>
