NMONVisualizer

fio

NMONVisualizer can process FIO files if the correct file naming scheme is used. Files must be named like id_timestamp_type.log where id can be anything (usually the hostname), timestamp is in yyyymmdd_hhmmss format and the type is one of the fio outputs.This can be accomplished by adding the following to the fio config file:
write_bw_log=${ID}_${DATETIME} write_lat_log=${ID}_${DATETIME} write_iops_log=${ID}_${DATETIME}
This ensures all log files have the correct format. Then, fio can be run as ID=`hostname` DATETIME=`date +%Y%m%d_%H%M%S` fio config.fio to set ID and DATETIME.
