Description

```
$ ceph tell osd.11 bench help
help not valid: help doesn't represent an int
Invalid command: unused arguments: [u'help']
bench {<int>} {<int>} {<int>} {<int>} : OSD benchmark: write <count> <size>-byte objects, (default 1G size 4MB). Results in log.
Error EINVAL: invalid command
```

On the left side it says about 4 integers, and in the description part only two of them.

moreover, it says that first number is a count of block, but actually it is the count of bytes for whole operation:

```
$ ceph tell osd.11 bench 1000 4096 {
"bytes_written": 1000,
"blocksize": 4096,
"elapsed_sec": 0.000153,
"bytes_per_sec": 6548917.136551,
"iops": 1598.856723
}
