Registers a frame to receive all fired events; it is not advisable to use this for anything except debugging purposes, as the incurred performance penalty is quite large.

frame:RegisterAllEvents();

Example

-- Addon '\Interface\Addons\My Addon'
MySavedVariables_Table = {} -- Global (not PerCharacter) SavedVariable
local frame = CreateFrame('Frame')
frame:RegisterAllEvents()
frame:SetScript('OnEvent',
    function(self, event, ...)
        -- Save only the last instance of the fired event.
        MySavedVariables_Table[event] = {...};
    end
)

Result

File '\WTF\Account\(...)\SavedVariables\My Addon.lua' will contain the MySavedVariables_Table variable, formatted something like this:

MySavedVariables_Table = {
    ["ADDON_LOADED"] = {
        [1] = "Some other addon",
    },
    ["ADDON_ACTION_FORBIDDEN"] = {
        [1] = "Some other addon",
        [2] = "CastSpellByName",
    },
    ...
}
