### Build from source
rake build
## How to use: case study
### Monitor IO performance of /dev/sda for each 0.1 second
$ perfmonger record -i 0.1 -d sda
### Monitor CPU usage for each 0.1 second
$ perfmonger record -i 0.1
### Monitor CPU usage and IO performance of /dev/sda, sdb for each 0.1 second
$ perfmonger record -i 0.1 -d sda -d sdb
### Plot CPU and IOPS
$ perfmonger record -i 0.1 -C -d sda > /tmp/perfmonger.log & sleep 10; pkill perfmonger
$ perfmonger plot -o /path/to/output_dir/ -Tpng /tmp/perfmonger.log
$ display /path/to/output_dir/read-iops.png
$ display /path/to/output_dir/cpu.png
