https://github.com/axboe/fio/pull/3 The above patch modifies the CSV latency log (write_lat_log options) by appending the filename to which the record is related. Said differently, the filename to which the I/O was issued to. When I first set out to add this feature I had indended to create a new log file in order to distrubt the latency log file format as little as possible. This, however, was not easily doable given the structure of the fio code. Now, in order to still provide this feature while maintaining the legacy latency file format I propose two options. (1) A configuration options as an extention to write_lat_log. For example: write_lat_log=mylogfile:with_filename (2) As a seperate configuration option that modifies the write_lat_log format. For example: write_lat_log_with_filename=bool
This email is to start a discussion and solicit feedback on the proposed feature as well as the cooresponding configuration trigger. -Chris -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
