CSV headers are wrong -- two missing columns

[Tel]

If you run with -x4 or similar to output a CSV and then load up the CSV into a spreadsheet (e.g. gnumeric) then you see the columns don't line up with the headers properly. I believe that two extra header items are required.

This is with Ubuntu 10.04.2 LTS

bonnie++ version 1.96

Note that I recompiled from source to give bigger values to Seeks and UpdateSeek in order to test a RAID system that is faster than the standard bonnie++ compile values can cater for. However, I pulled down the ubuntu source archive (with "apt-get source" and the CSV headers are the same as earlier testing on the same version from the ubuntu binary package).

I will add some files below.

Here are two CSV outputs from bonnie++ that I generated (note the ===== lines are stuff I put in myself to separate the O_DIRECT trial run from the non O_DIRECT trial run). I've put all the outputs into a single file. The series was generated with:

bonnie++ -f -s 33000:4096 -n 1024 -x4 -D

Also, same again without the "-D" option.

Here is the same in gnumeric format. Note that the columns do not line up. It does not make sense that the file_size would be 1 and the io_chunk_size would be 1327979580 because actually these headers should be two steps over.

Actually file_size should really be 33000M and io_chunk_size should be 4k.

Most probably the two missing columns in the header are "concurrency" and "random_seed", that's my best guess. This would just require a change to a print statement to fix (but it makes a big difference when reading out the results).
