首先是开启监控器方法,向Global注入RawsetGlobal方法

function Profiler:StartMonitor(type)
    self.MonitorType = type
    self.MemoryState = {}
    self.StartMemory = collectgarbage("count")
    self.CurrentMemory = self.StartMemory
    self.MonitorGlobal = {}
    setmetatable(_G, { __newindex = Profiler.RawsetGlobal })
    if type ~= self.MonitorType.Line or nil then
        self.MonitorStartTime = os.clock()
        self.FunctionTable = {}
        debug.sethook(Profiler.FunctionMonitor,type.Type,0)
    else
        debug.sethook(Profiler.LineMonitor,type.Type,0)
    end
end

function Profiler.RawsetGlobal(tb,k,v)
    local t = {}
    local info = debug.getinfo(2, "nlS")
    t.CurrentLine = info.currentline
    t.SrcFile = info.short_src
    t.FunctionName = info.name or 'Anonymous'
    t.Key = k
    t.Value = v
    Profiler.MonitorGlobal[k] = t
    rawset(tb, k, v)
end
