Here's some test code.

Note on the client you'll have to set profiler_allowSaveNatives true

CreateThread(function()
    local profilerStarted = false
    local profilerId = 0
    while true do
        if not profilerStarted then
            profilerStarted = true
            print("started")
            ProfilerStartRecording(50)
        elseif not ProfilerIsRecording() then
            print("save")
            profilerId = profilerId + 1
            local jsonFile = ProfilerSaveToJson()
            local msgPackFile = ProfilerSaveToMsgpack()
            print("json", jsonFile)
            print("msgpack", msgPackFile)
            profilerStarted = false
        end
        Wait(0)
    end
end)

The implementation has swapped from taking a string value as the file name, to defining one based on the current time of day to not allow the functions to be used maliciously.

This also adds a profiler:/ vfs to save profiler recordings to so they wont set in the base directory.
