XfsMonkey is simply a script that runs CrashMonkey in a loop to test multiple workloads.
To run XFSMonkey, first get CrashMonkey up and working. XFSMonkey accepts the same parameters as CrashMonkey standalone tests. To get a list of all supported flags and their default setting, run python xfsMonkey.py -h in the root directory of CrashMonkey repository. If you have a directory of workloads to be tested, say build/tests/test_workloads, you can invoke the xfsMonkey script using python xfsMonkey.py -t btrfs -u /build/tests/test_workloads. This will test all the workloads under the input directory with CrashMonkey (uses auto-checker by default), and outputs the test summary in a log file <date_timestamp>-xfsMonkey.log. In addition, each test case that was run has a detailed log file <date_timestamp>-test_name.log, that can be found in the build directory.
