Getting Data In

Scripted input for iostat only ingesting headers

I've added the Splunk TA for Unix/Linux to my indexers and have been trying to get iostat data feeding in from the indexers.

The script run, but only the headers are present
Sample _raw:
Device rReq_PS wReq_PS rKB_PS wKB_PS avgWaitMillis avgSvcMillis bandwUtilPct

Running 'iostat -xk 1 2' as the script is setup to do does return results.

Running the script normally/debug only shows the headers output to screen, but the debug file show it pulling recording the statistics:
debug--iostat.sh file Output:

 The only thing I can think is that there is some issue with the awk statement maybe? So I be manually adjusting the script?

Found my own answer - TA was very out of date. 8.3.0 is working
