This is all good when working directly with the tools. But for CI integration it's a bit of pain. Furthermore, not all rt-tests use the same output format. By using some easy to parse existing machine-readable format we can use standard libraries to parse the data. For example in jitterdebug there is a short Python program[1] to visualize either the histogram[2] or all samples[3]. The implementation for JSON output for this is very simple. The last patch adds a version of jitterdebugs's JSON output, which looks like { "file_version": 1, "version:": "cyclictest V 1.90", "num_threads": 2, "resolution_in_ns": 0, "cmdline:": "./cyclictest --affinity=1-2 --duration=1s --output=dump.json -h 1000 -p 80", "sysinfo": { "sysname": "Linux", "nodename": "beryllium", "release": "5.9.14-1-default", "version": "#1 SMP Sat Dec 12 06:57:32 UTC 2020 (c648a46)", "machine": "x86_64" }, "thread": { "0": { "histogram": { "0": 16, "1": 853, "2": 80, "3": 50, "4": 1 }, "cycles": 1000, "min": 0, "max": 4, "avg": 1.17, "cpu": 1, "node": 0 }, "1": { "histogram": { "0": 14, "1": 833, "2": 93, "3": 56, "4": 4 }, "cycles": 1000, "min": 0, "max": 4, "avg": 1.20, "cpu": 2, "node": 0 } } } It's just a rough version. I didn't try to make it generic for the other rt-tests or make it as plugin as John was suggesting. I'd think we could make this feature as compile option, if you want to keep the program small. Obviously, we could also make the terminal output a compile option, to keep it small. Anyway, what do you think about it?
