Each cache consumer (IDP cache, token store, PKCE store, secrets manager,
EDR validator) was independently calling NewStore, creating separate Redis
clients with their own connection pools — up to 1400 potential connections
from a single management server process.
Introduce a shared CacheStore() singleton on BaseServer that creates one
store at boot and injects it into all consumers. Consumer constructors now
receive a store.StoreInterface instead of creating their own.
For Redis mode, all consumers share one connection pool (1000 max conns).
For in-memory mode, all consumers share one GoCache instance.
* Add client metrics
* Add client metrics system with OpenTelemetry and VictoriaMetrics support
Implements a comprehensive client metrics system to track peer connection
stages and performance. The system supports multiple backend implementations
(OpenTelemetry, VictoriaMetrics, and no-op) and tracks detailed connection
stage durations from creation through WireGuard handshake.
Key changes:
- Add metrics package with pluggable backend implementations
- Implement OpenTelemetry metrics backend
- Implement VictoriaMetrics metrics backend
- Add no-op metrics implementation for disabled state
- Track connection stages: creation, semaphore, signaling, connection ready, and WireGuard handshake
- Move WireGuard watcher functionality to conn.go
- Refactor engine to integrate metrics tracking
- Add metrics export endpoint in debug server
* Add signaling metrics tracking for initial and reconnection attempts
* Reset connection stage timestamps during reconnections to exclude unnecessary metrics tracking
* Delete otel lib from client
* Update unit tests
* Invoke callback on handshake success in WireGuard watcher
* Add Netbird version tracking to client metrics
Integrate Netbird version into VictoriaMetrics backend and metrics labels. Update `ClientMetrics` constructor and metric name formatting to include version information.
* Add sync duration tracking to client metrics
Introduce `RecordSyncDuration` for measuring sync message processing time. Update all metrics implementations (VictoriaMetrics, no-op) to support the new method. Refactor `ClientMetrics` to use `AgentInfo` for static agent data.
* Remove no-op metrics implementation and simplify ClientMetrics constructor
Eliminate unused `noopMetrics` and refactor `ClientMetrics` to always use the VictoriaMetrics implementation. Update associated logic to reflect these changes.
* Add total duration tracking for connection attempts
Calculate total duration for both initial connections and reconnections, accounting for different timestamp scenarios. Update `Export` method to include Prometheus HELP comments.
* Add metrics push support to VictoriaMetrics integration
* [client] anchor connection metrics to first signal received
* Remove creation_to_semaphore connection stage metric
The semaphore queuing stage (Created → SemaphoreAcquired) is no longer
tracked. Connection metrics now start from SignalingReceived. Updated
docs and Grafana dashboard accordingly.
* [client] Add remote push config for metrics with version-based eligibility
Introduce remoteconfig.Manager that fetches a remote JSON config to control
metrics push interval and restrict pushing to a specific agent version
range. When NB_METRICS_INTERVAL is set, remote config is bypassed
entirely for local override.
* [client] Add WASM-compatible NewClientMetrics implementation
Replace NewClientMetrics in metrics.go with a WASM-specific stub in metrics_js.go, returning nil for compatibility with JS builds. Simplify method usage for WASM targets.
* Add missing file
* Update default case in DeploymentType.String to return "unknown" instead of "selfhosted"
* [client] Rework metrics to use timestamped samples instead of histograms
Replace cumulative Prometheus histograms with timestamped point-in-time
samples that are pushed once and cleared. This fixes metrics for sparse
events (connections/syncs that happen once at startup) where rate() and
increase() produced incorrect or empty results.
Changes:
- Switch from VictoriaMetrics histogram library to raw Prometheus text
format with explicit millisecond timestamps
- Reset samples after successful push (no resending stale data)
- Rename connection_to_handshake → connection_to_wg_handshake
- Add netbird_peer_connection_count metric for ICE vs Relay tracking
- Simplify dashboard: point-based scatter plots, donut pie chart
- Add maxStalenessInterval=1m to VictoriaMetrics to prevent forward-fill
- Fix deployment_type Unknown returning "selfhosted" instead of "unknown"
- Fix inverted shouldPush condition in push.go
* [client] Add InfluxDB metrics backend alongside VictoriaMetrics
Add influxdb.go with timestamped line protocol export for sparse
one-shot events. Restore victoria.go to use proper Prometheus
histograms. Update Grafana dashboards, add InfluxDB datasource,
and update docs.

* [client] Fix metrics issues and update dev docker setup
- Fix StopPush not clearing push state, preventing restart
- Fix race condition reading currentConnPriority without lock in recordConnectionMetrics
- Fix stale comment referencing old metrics server URL
- Update docker-compose for InfluxDB: add scoped tokens, .env config, init scripts
- Rename docker-compose.victoria.yml to docker-compose.yml
* [client] Add anonymised peer tracking to pushed metrics
Introduce peer_id and connection_pair_id tags to InfluxDB metrics.
Public keys are hashed (truncated SHA-256) for anonymisation. The
connection pair ID is deterministic regardless of which side computes
it, enabling deduplication of reconnections in the ICE vs Relay
dashboard. Also pin Grafana to v11.6.0 for file-based provisioning
and fix datasource UID references.
* Remove unused dependencies from go.mod and go.sum
* Refactor InfluxDB ingest pipeline: extract validation logic
- Move line validation logic to `validateLine` and `validateField` helper functions.

* Revert influxdb in docker compose
* Enable gzip compression and authorization validation for metrics push and ingest
* Reducate code of complexity
* Update debug documentation to include metrics.txt description
* Increase `maxBodySize` limit to 50 MB and update gzip reader wrapping logic
* Refactor deployment type detection to use URL parsing for improved accuracy
* Update readme
* Throttle remote config retries on fetch failure
* Preserve first WG handshake timestamp, ignore rekeys
* Skip adding empty metrics.txt to debug bundle in debug mode
* Update default metrics server URL to https://ingest.netbird.io
* Atomic metrics export-and-reset to prevent sample loss between Export and Reset calls
* Fix doc
* Refactor Push configuration to improve clarity and enforce minimum push interval
* Remove `minPushInterval` and update push interval validation logic
* Revert ExportAndReset, it is acceptable data loss
* Fix metrics review issues: rename env var, remove stale infra, add tests
- Rename NB_METRICS_ENABLED to NB_METRICS_PUSH_ENABLED to clarify that
collection is always active (for debug bundles) and only push is opt-in
- Change default config URL from staging to production (ingest.netbird.io)
- Delete broken Prometheus dashboard (used non-existent metric names)
- Delete unused VictoriaMetrics datasource config
- Replace committed .env with .env.example containing placeholder values
- Wire Grafana admin credentials through env vars in docker-compose
- Make metricsStages a pointer to prevent reset-vs-write race on reconnect
- Fix typed-nil interface in debug bundle path (GetClientMetrics)
- Use deterministic field order in InfluxDB Export (sorted keys)
- Replace Authorization header with X-Peer-ID for metrics push
- Fix ingest server timeout to use time.Second instead of float
- Fix gzip double-close, stale comments, trim log levels
- Add tests for influxdb.go and MetricsStages
* Add login duration metric, ingest tag validation, and duration bounds
- Add netbird_login measurement recording login/auth duration to management
server, with success/failure result tag
- Validate InfluxDB tags against per-measurement allowlists in ingest server
to prevent arbitrary tag injection
- Cap all duration fields (*_seconds) at 300s instead of only total_seconds

* Fix Grafana dashboard: add arch to drop columns, add login panels
* Validate NB_METRICS_SERVER_URL is an absolute HTTP(S) URL
* Address review comments: fix README wording, update stale comments
* Clarify env var precedence does not bypass remote config eligibility
* Remove accidentally committed pprof files

Auto-update logic moved out of the UI into a dedicated updatemanager.Manager service that runs in the connection layer. The
UI no longer polls or checks for updates independently.
The update manager supports three modes driven by the management server's auto-update policy:
No policy set by mgm: checks GitHub for the latest version and notifies the user (previous behavior, now centralized)
mgm enforces update: the "About" menu triggers installation directly instead of just downloading the file — user still initiates the action
mgm forces update: installation proceeds automatically without user interaction
updateManager lifecycle is now owned by daemon, giving the daemon server direct control via a new TriggerUpdate RPC
Introduces EngineServices struct to group external service dependencies passed to NewEngine, reducing its argument count from 11 to 4
* [client] Fix exit node menu not refreshing on Windows
TrayOpenedCh is not implemented in the systray library on Windows,
so exit nodes were never refreshed after the initial connect. Combined
with the management sync not having populated routes yet when the
Connected status fires, this caused the exit node menu to remain empty
permanently after disconnect/reconnect cycles.
Add a background poller on Windows that refreshes exit nodes while
connected, with fast initial polling to catch routes from management
sync followed by a steady 10s interval. On macOS/Linux, TrayOpenedCh
continues to handle refreshes on each tray open.
Also fix a data race on connectClient assignment in the server's connect()
method and add nil checks in CleanState/DeleteState to prevent panics
when connectClient is nil.
* Remove unused exitNodeIDs
* Remove unused exitNodeState struct
Capture engine reference before actCancel() in cleanupConnection().
After actCancel(), the connectWithRetryRuns goroutine sets engine to nil,
causing connectClient.Stop() to skip shutdown. This allows the goroutine
to set ErrResetConnection on the shared state after Down() clears it,
causing the next Up() to fail.
Up() acquired s.mutex with a deferred unlock, then called waitForUp()
while still holding the lock. waitForUp() blocks for up to 50 seconds
waiting on clientRunningChan/clientGiveUpChan, starving all concurrent
gRPC calls that require the same mutex (Status, ListProfiles, etc.).
Replace the deferred unlock with explicit s.mutex.Unlock() on every
early-return path and immediately before waitForUp(), matching the
pattern already used by the clientRunning==true branch.
CLI: new expose command to publish a local port with flags for PIN, password, user groups, custom domain, name prefix and protocol (HTTP default).
Management/API: create/renew/stop expose sessions (streamed status), automatic naming/domain, TTL renewals, background expiration, new management RPCs and client methods.
UI/API: account settings now include peer_expose_enabled and peer_expose_groups; new activity codes for peer expose events.
could interleave with a sleep/wake event causing out-of-order state
transitions. The mutex now covers the full duration of each handler
including the status check, the Up/Down call, and the flag update.
Note: if Up or Down commands are triggered in parallel with sleep/wake
events, the overall ordering of up/down/sleep/wake operations is still
not guaranteed beyond what the mutex provides within the handler itself.
* Consolidate authentication logic
- Moving auth functions from client/internal to client/internal/auth package
- Creating unified auth.Auth client with NewAuth() constructor
- Replacing direct auth function calls with auth client methods
- Refactoring device flow and PKCE flow implementations
- Updating iOS/Android/server code to use new auth client API
* Refactor PKCE auth and login methods
- Remove unnecessary internal package reference in PKCE flow test
- Adjust context assignment placement in iOS and Android login methods
When Down() and Up() are called in quick succession, the connectWithRetryRuns goroutine could set ErrResetConnection after Down() had cleared the state, causing the subsequent Up() to fail.
Fix by waiting for the goroutine to exit (via clientGiveUpChan) before Down() returns. Uses a 5-second timeout to prevent RPC timeouts while ensuring the goroutine completes in most cases.
Embed Dex as a built-in IdP to simplify self-hosting setup.
Adds an embedded OIDC Identity Provider (Dex) with local user management and optional external IdP connectors (Google/GitHub/OIDC/SAML), plus device-auth flow for CLI login. Introduces instance onboarding/setup endpoints (including owner creation), field-level encryption for sensitive user data, a streamlined self-hosting provisioning script, and expanded APIs + test coverage for IdP management.

- Release syncMsgMux before waiting for shutdownWg to prevent deadlock
- Check context inside lock in handleSync and receiveSignalEvents
- Prevents nil pointer access when messages arrive during engine stop
Adds a new NotifyOSLifecycle RPC and server handler to centralize OS sleep/wake handling, introduces Server.sleepTriggeredDown for coordination, updates client UI to call the new RPC, and adjusts the internal sleep event enum zero-value semantics.
The status cmd will not be blocked by the ICE probe
Refactor the TURN and STUN probe, and cache the results. The NetBird status command will indicate a "checking…" state.
This PR improves the NetBird client's status checking mechanism by implementing earlier detection of client state changes and better handling of connection lifecycle management. The key improvements focus on:
• Enhanced status detection - Added waitForReady option to StatusRequest for improved client status handling
• Better connection management - Improved context handling for signal and management gRPC connections• Reduced connection timeouts - Increased gRPC dial timeout from 3 to 10 seconds for better reliability
• Cleaner error handling - Enhanced error propagation and context cancellation in retry loops
Key Changes
Core Status Improvements:
- Added waitForReady optional field to StatusRequest proto (daemon.proto:190)
- Enhanced status checking logic to detect client state changes earlier in the connection process
- Improved handling of client permanent exit scenarios from retry loops
Connection & Context Management:
- Fixed context cancellation in management and signal client retry mechanisms
- Added proper context propagation for Login operations
- Enhanced gRPC connection handling with better timeout management
Error Handling & Cleanup:
- Moved feedback channels to upper layers for better separation of concerns
- Improved error handling patterns throughout the client server implementation
- Fixed synchronization issues and removed debug logging
The client status is not enough to protect the RPC calls from concurrency issues, because it is handled internally in the client in an asynchronous way.
