The requests in the input file are run 10 times, with a delay of 5000 milliseconds (5 seconds) between
invocations.
2. Here is the previous example with the -p flag:
mmpmon -i infile -p -r 10 -d 5000
The output (sent to stdout) is similar to this:
_ver_ _n_ 192.168.1.8 _nn_ node1 _v_ 2 _lv_ 3 _vt_ 0
_io_s_ _n_ 192.168.1.8 _nn_ node1 _rc_ 0 _t_ 1084195701 _tu_ 350714 _br_ 0 _bw_ 0 _oc_ 0

_fs_io_s_ _n_ 192.168.1.8 _nn_ node1 _rc_ 1 _t_ 1084195701 _tu_ 364489 _cl_ - _fs_ -_rhist_
_n_ 192.168.1.8 _nn_ node1 _req_ off _rc_ 0 _t_ 1084195701 _tu_ 378217
3. This is an example of fs_io_s with a mounted file system:
mmpmon node 198.168.1.8 name node1 fs_io_s OK
cluster: node1.localdomain
filesystem: gpfs1
disks: 1
timestamp: 1093352136/799285
bytes read: 52428800
bytes written: 87031808
opens: 6
closes: 4
reads: 51
writes: 83
readdir: 0
inode updates: 11
mmpmon node 198.168.1.8 name node1 fs_io_s OK
cluster: node1.localdomain
filesystem: gpfs2
disks: 2
timestamp: 1093352136/799285

4. Here is the previous example with the -p flag:
_fs_io_s_ _n_ 198.168.1.8 _nn_ node1 _rc_ 0 _t_ 1093352061 _tu_ 93867 _cl_ node1.localdomain
_fs_ gpfs1 _d_ 1 _br_ 52428800 _bw_ 87031808 _oc_ 6 _cc_ 4 _rdc_ 51 _wc_ 83 _dir_ 0 _iu_ 10
_fs_io_s_ _n_ 198.168.1.8 _nn_ node1 _rc_ 0 _t_ 1093352061 _tu_ 93867 _cl_ node1.localdomain
_fs_ gpfs2 _d_ 2 _br_ 87031808 _bw_ 52428800 _oc_ 4 _cc_ 3 _rdc_ 12834 _wc_ 50 _dir_ 0 _iu_ 8
This output consists of two strings.
5. This is an example of io_s with a mounted file system:
mmpmon node 198.168.1.8 name node1 io_s OK
timestamp: 1093351951/587570
bytes read: 139460608
