Benson Wong a4b91e08cf Changes and fixes before the release (docs/small tweaks) (#750)
- update README.md with new docker instructions
- update docs/configuration.md
- update .github/workflows to have pinned action versions
- gofmt events package
- fix small bugs in CI scripts
- reduce config options for internal/perf/monitor and config. A ring buffer is used to keep 1hr of entries at max 5s granularity. For long term stats use prometheus monitoring on /metrics

Fixes #744

Benson Wong 7e3e94a08a proxy,ui: add performance monitoring with Prometheus metrics (#743)
Add a comprehensive performance monitoring system that collects CPU, memory, swap, load average, network IO, and GPU stats. Provides both a REST API for the UI and a Prometheus /metrics endpoint.

Backend changes:
- New internal/perf package with configurable interval-based stats collection
- GPU monitoring via LACT (Unix socket) and nvidia-smi fallback on Linux
- Ring buffer (internal/ring) for time-series stat storage
- Prometheus /metrics endpoint with all system and GPU metrics
- Moved LogMonitor to internal/logmon package
- New PerformanceConfig for hot-reloadable monitoring settings
- REST /api/performance endpoint replacing SSE streaming

UI changes:
- New Performance page with real-time charts for CPU, memory, GPU, and network
- Reusable PerformanceChart component
- LLAMA_SWAP_URL environment variable support
- Improved capture dialog display

Other:
- Example Grafana dashboard for Prometheus metrics
- monitor-test standalone binary
- Config schema and example updates

Benson Wong 11b7913287 llama-swap.go: remove debounce, replace fmt.Printlns (#731)
small fixes to clean up the main(): 

- remove the debounced config reload 
- replace fmt.Println with a proxy.LogMonitor for consistency

Benson Wong 66639e83f7 proxy: replace fsnotify with stat-poll watcher and add SIGHUP reload (#685)
The fsnotify-based config watcher does not work reliably when the config
file is bind-mounted into a Docker container as an individual file, and
mishandles k8s ConfigMap projections (atomically swapped symlinks).
Replace it with a small os.Stat-polling watcher and add SIGHUP as an
explicit reload signal.

- new proxy/configwatcher package: 2s os.Stat poller, follows symlinks,
  fires on mtime/size change and on missing -> present transitions
- SIGHUP triggers reload unconditionally (works without --watch-config)
  via the same ConfigFileChangedEvent pipeline so the UI sees identical
  state transitions
- watcher goroutine now exits cleanly on shutdown via a context
- drop github.com/fsnotify/fsnotify dependency

- Implement SetVersion method to configure version info in ProxyManager
- Add version info fetching to APIProvider and display in ConnectionStatus component
- Include version info in UI context and update dependencies
- Add tests for version endpoint functionality

David Wen Riccardi-Zhu 6516532568 Add optional TLS support (#340)
* Add optional TLS support

Introduce HTTPS support with net/http Server.ListenAndServeTLS.

This should enable the option of serving via HTTPS without a reverse
proxy.

Add two flags:
- tls-cert-file (path to the TLS certificate file)
- tls-key-file (path to the TLS private key file)

Both flags must be supplied together; otherwise exit with error.

If both flags are present, call srv.ListenAndServeTLS.
If not, fall back to the existing srv.ListenAndServe (HTTP); no changes
to existing non‑TLS behavior.

Benson Wong 216c40b951 proxy/config: create config package and migrate configuration (#329)
* proxy/config: create config package and migrate configuration

The configuration is become more complex as llama-swap adds more
advanced features. This commit moves config to its own package so it can
be developed independently of the proxy package.

Additionally, enforcing a public API for a configuration will allow
downstream usage to be more decoupled.

Benson Wong 6a058e4191 Change fsnotify to watch config directory instead of file
The fsnotify library suggests watching a directory and checking that the
name matches the configuration file.

Benson Wong 1921e570d7 Add Event Bus (#184)
Major internal refactor to use an event bus to pass event/messages along. These changes are largely invisible user facing but sets up internal design for real time stats and information.

- `--watch-config` logic refactored for events
- remove multiple SSE api endpoints, replaced with /api/events
- keep all functionality essentially the same
- UI/backend sync is in near real time now

Benson Wong 519c3a4d22 Change /unload to not wait for inflight requests (#125)
Sometimes upstreams can accept HTTP but never respond causing requests
to build up waiting for a response. This can block Process.Stop() as
that waits for inflight requests to finish. This change refactors the
code to not wait when attempting to shutdown the process.

Benson Wong 448ccae959 Introduce Groups Feature (#107)
Groups allows more control over swapping behaviour when a model is requested. The new groups feature provides three ways to control swapping: within the group, swapping out other groups or keep the models in the group loaded persistently (never swapped out). 

Closes #96, #99 and #106.

Benson Wong 09bdd86b54 Improve shutdown behaviour (#47) (#49)
Introduce `Process.Shutdown()` and `ProxyManager.Shutdown()`. These two function required a lot of internal process state management refactoring. A key benefit is that `Process.start()` is now interruptable. When `Shutdown()` is called it will break the long health check loop. 

State management within Process is also improved. Added `starting`, `stopping` and `shutdown` states. Additionally, introduced a simple finite state machine to manage transitions.

Benson Wong baeb0c4e7f Add cmd_stop configuration to better support docker (#35)
Add `cmd_stop` to model configuration to run a command instead of sending a SIGTERM to shutdown a process before swapping.

Replace previously hardcoded value for `/health` to check when the

any server that provides an an OpenAI compatible inference endpoint.
