+Terse output
+------------
+
+For scripted usage where you typically want to generate tables or graphs
+of the results, fio can output the results in a comma seperated format.
+The format is one long line of values, such as:

+client1,0,0,936,331,2894,0,0,0.000000,0.000000,1,170,22.115385,34.290410,16,714,84.252874%,366.500000,566.417819,3496,1237,2894,0,0,0.000000,0.000000,0,246,6.671625,21.436952,0,2534,55.465300%,1406.600000,2008.044216,0.000000%,0.431928%,1109

+Split up, the format is as follows:
+
+ jobname, groupid, error
+ READ status:
+ KiB IO, bandwidth (KiB/sec), runtime (msec)
+ Submission latency: min, max, mean, deviation
+ Completion latency: min, max, mean, deviation
+ Bw: min, max, aggreate percentage of total, mean, deviation
+ WRITE status:
+ KiB IO, bandwidth (KiB/sec), runtime (msec)
+ Submission latency: min, max, mean, deviation
+ Completion latency: min, max, mean, deviation
+ Bw: min, max, aggreate percentage of total, mean, deviation
+ CPU usage: user, system, context switches
