OnEventWatch (Continued)

A profiling tool that estimates how long OnEvent handlers take to run, per frame.

Originally written by Gello in 2006 for vanilla WoW. This fork updates the addon to work with Burning Crusade Classic (and Anniversary Edition).

Usage

Type /onevent to start watching. The addon enumerates all frames with OnEvent handlers and wraps them with debugprofilestart()/debugprofilestop() timing.

Type /onevent again to toggle the tracking window, which shows:

• Frame — the frame name (anonymous frames get numbered)
• Event — which event fired
• Count — how many times it fired
• Time — total estimated processing time
• Avg — average time per event

Click column headers to sort. Use the search boxes to filter by frame name or event name.

Buttons

• All — clear search filters
• Reset — clear all collected data
• Stop — reload UI to remove all hooks
• Ok — close the window

Tips

• Shift+click an event row to insert its stats into chat (for copy/paste)
• A minimap button appears as a reminder that hooks are active
• Due to microscopic times involved, treat measurements as comparative, not absolute
• This only watches OnEvent handlers. OnUpdate, OnClick, etc. are not captured.
