Bill, Format of entries is: time, rate/latency, data direction, block size Time: in milliseconds. Bandwidth logs are usually 500 or 1000ms apart; that can be controlled by the config file with "bwavgtime=[x ms]". Rate/latency: for bandwidth, this is in KB/sec. For latency, it's microseconds. Data direction: 0 is read, 1 is write. Block size: block size of IOs in bytes. For those using R to analyze log files, I have some useful stuff here: https://github.com/joshcarter/fio_tools In particular, /analysis/fio_log_parsers.R has read_bw_log() and read_lat_log() functions.
