Ruis is a tool to profile application and ease the identification of bottleneck.

Using RUIS is a two step process:

1. Profiling the application using ruis utility.
2. Generating a report for the application.

To gather profiling information on your application use the following commands:

export CMD='command arg1 arg2'
export COLLECTL_OPT='--all --verbose --home'  # Optional
./ruis.sh $CMD

Or using inline-command as follow:

export COLLECTL_OPT='--all --verbose --home'  # Optional
./ruis.sh 'command arg1 arg2'

The default collectl options for RUIS are: -sCDNfM -omT --dskopts z --cpuopts z -i .1 Note: for additional collectl options see the man page

This step allows the generation of a report containing:

• Basic text based metrics of the application.
• Timeseries visualisation of the application profiling.
• Summarize the time used for CPU, Disk I/O, and Network I/O.

Refer to report-example.ipynb for an example.
