Missing/incorrect ClassicAPI.dll causes errors and a blank grey readout; add setup and troubleshooting notes. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
OctoLatency
A lightweight latency monitor for Vanilla WoW (1.12.1). Shows a small, movable, color-coded latency readout on your screen.
Requirements
- ClassicAPI.dll must be installed before you install this addon. Without
it, the addon will throw errors and the readout will show as an empty grey
box with no text/numbers inside it.
- You'll need to add
ClassicAPI.dllto your client'sdll.txt(the entry is case-sensitive).
- You'll need to add
What it does
- Displays your current world latency (falls back to home latency if world
isn't available) as
NNN msnext to your screen. - Color-codes the number so you can tell your connection quality at a glance:
- Green — under 150 ms (good)
- Yellow — 150-350 ms (moderate)
- Red — over 350 ms (critical)
- Hover the frame for a tooltip with home latency, world latency, and bandwidth.
- Updates every 2 seconds (not every frame), so it has no meaningful impact on game performance.
Options
There's no settings panel — the addon is intentionally minimal. The only "option" is position:
- Move it: left-click and drag the frame anywhere on screen. Its position is saved automatically and restored on your next login.
Error reporting
If something inside the addon errors (e.g. an unexpected GetNetStats()
response), it's caught instead of spamming a Lua error popup, and logged for
you to report:
/octolat errors— print the last 20 logged errors (with timestamps) to chat./octolat copyerrors— open a copy-paste window with the same log, since vanilla WoW's chat frame doesn't let you select/copy its text. The window opens with the text already highlighted, so you can just press Ctrl+C./octolat clearerrors— clear the error log.
The log is also saved to your SavedVariables file, so it survives
logout/relog.
Troubleshooting
- Grey box with no numbers / constant errors: This almost always means
ClassicAPI.dllisn't installed correctly. Check that:ClassicAPI.dllis present in your client folder.- It's listed in
dll.txtexactly asClassicAPI.dll(matching case — the entry is case-sensitive). - After adding it, fully restart the client (not just
/reload).
