I wanted to compare fio results from before and after using dmcrypt and add the cpu utilization. Currently I have such a fio config[1] running generating a default outputfile[2]. What would be the advised way to generate output with timestamps that I can eg. insert into a time series db so I can view the fio and load in some grafana chart. Are there maybe modules that output data every 10s to influx or prometheus?
