How to extract these individual fields for iostat data?

[jodros]

I am having a difficult time extracting fields for data returned by iostat. Has anyone been able to extract these individual fields? Data below:

Device   rReq_PS   wReq_PS   rKB_PS   wKB_PS  avgWaitMillis  avgSvcMillis  bandwUtilPct
sda       0.00     208.00     0.00    1644.00     1.45           0.02          0.50
sda1      0.00     0.00       0.00     0.00       0.00           0.00          0.00
sda2      0.00     0.00       0.00     0.00       0.00           0.00          0.00
sda5      0.00     208.00     0.00    1644.00     1.45           0.02          0.50
sda6      0.00     0.00       0.00     0.00       0.00           0.00          0.00

Does multikv not work for you?

| stats count | eval _raw="<your data above>" | multikv | fields - _raw count

Seems to work as expected.
