rt-app - Test application for simulating a real-time periodic load
rt-app <config-file>
rt-app is a test application that starts multiple periodic threads in order to simulate a real-time periodic load.
The code is currently maintained on GitHub:
https://github.com/scheduler-tools/rt-app
rt-app runs on GNU/Linux. It needs json-c to run, and a 3.14 or later linux kernel supporting the SCHED_DEADLINE policy (unless built without the optional libdl).
rt-app <config_file> where config file is a full/relative path to a JSON file or "-" (without quotes) to read JSON data from stdin.
See /usr/share/doc/rt-app/tutorial.txt for details of the JSON config file format
workgen <config_file> can be used instead of rt-app directly. It allows more freedom in writing the JSON workload files, by having a less strict grammar which is useful for defining multiple similar events. It will parse, check and update the JSON workload file before passing it to rt-app. See workgen(7)
The python merge script (
/usr/share/doc/rt-app/examples/merge.py ) can be used to combine JSON
snippets into the config file. e.g:
./merge.py -o combined.json global.json resources.json thread0.json
thread1.json thread2.json thread3.json
Numerous example workloads and building blocks can be found in /usr/share/doc/rt-app/examples/*.json
