...p attached disk
Inside vm i try to do some work via fio:
[global]
rw=randread
size=128m
directory=/tmp
ioengine=libaio
iodepth=4
invalidate=1
direct=1
[bgwriter]
rw=randwrite
iodepth=32
[queryA]
iodepth=1
ioengine=mmap
direct=0
thinktime=3
[queryB]
iodepth=1
ioengine=mmap
direct=0
thinktime=5
[bgupdater]
rw=randrw
iodepth=16
thinktime=40
size=128m
After that i try to get graph like iowatcher -t test.trace -o trace.svg
But svg contains unreadable images. What i doing wrong and how can i fix that?
svg looks like http://62.76.182.4/trace.svg
Thank you for good tools !
