The Charts view could break usage down by user, group or total, but not by model. Per-model data existed only as day-window attempt and failure counts, which measure availability rather than delivered usage. A served model now accumulates the same four metrics a user or group does. The scope kind is "model" and its id is the canonical "provider/model", so a request that fails over counts against the provider that answered it, and one bare id served by two providers ranks as two rows. The request counter is written after the response, in the batch that already writes tokens and cost. That is the first point at which the serving model is known, so no extra round trip is needed and admission never double counts. GET /admin/api/usage/models ranks models for one metric and window. It returns only models with non-zero usage, by operator requirement: the catalog runs to hundreds of models and a padded ranking is unreadable. The read stays one storeGetMulti over the catalog. The Charts view gains a Models tab with its own metric picker, and the scope picker gains the models that have traffic.
Admin panel (webui)
Source for the traefik-llmgateway read-only admin dashboard: Vue 3 + TypeScript + Pinia + Tailwind v4 + shadcn-vue + Chart.js, built with Vite.
See the repo root README.md's Admin section for what
the dashboard shows and how its API/auth works, and the
Development section for make admin-ui — the
only way this directory's output (../admin_assets_gen.go) is meant to be
regenerated. Nothing here runs at request time: the plugin serves the
built, baked-in output, never webui/ itself.
Warning: shadcn-vue add/init regressions
components.json has no iconLibrary or font key. Do not add them
back. Their omission is the fix, not an oversight — read on before you
"helpfully" restore either one.
Earlier revisions of this file set "iconLibrary": "lucide" and
"font": "inter", both wrong for this project (FontAwesome only, per
the vue-web-development house skill; no external font at all). Both
npx shadcn-vue init and npx shadcn-vue add <component> read those two
fields and, when set, rewrite src/assets/main.css — hit twice in this
project's own history, init then a later add, both re-adding a
@import url('https://fonts.googleapis.com/...') line and switching the
dark-mode @custom-variant back to a .dark-class toggle.
The actual shadcn-vue config schema
(node_modules/shadcn-vue/dist/schema/index.js's rawConfigSchema)
declares both fields as z.string().optional() — not an enum, contrary
to an earlier, incorrect claim in this project's own review notes that
the CLI schema forced one of five fixed values. The CLI's init --font/
--icon-library flags do offer five fixed choices each, but that is a
flag-parsing constraint, not a components.json schema constraint.
Deleting both keys leaves them undefined after parse, a valid state:
verified empirically, running npx shadcn-vue add badge -o -y against a
components.json with both keys removed left src/assets/main.css
byte-for-byte unchanged.
That verification also surfaced a narrower, remaining trap: the same run
still added @lucide/vue back to package.json's dependencies (Badge
itself does not use it — some components' registry entries list an icon
package regardless of iconLibrary). So after any future shadcn-vue add/init call:
- Check
git diff webui/package.jsonfor a re-addedlucide-vue-next/@lucide/vuedependency, and remove it (npm uninstall) if nothing insrc/imports from it. - Check the new component's own file for a
lucide-vue-next/@lucide/vueimport and swap it for the FontAwesome equivalent (seesrc/components/ui/select/Select*.vuefor the pattern already applied there). - Diff
src/assets/main.cssanyway before committing, in case a future shadcn-vue release starts reading a different config key for the same font-injection step.
Local development
npm ci
npm run dev # Vite dev server — /admin/api/* calls need a real
# gateway to fetch from; point one at the same origin or
# accept the "refresh failed" state while iterating on
# layout/styling alone.
npm run build # what `make admin-ui` runs, plus webui/generate.mjs
