- Redact PostgreSQL DSN password from stdout/logs
- Harden .dockerignore to exclude .ssh/, .claude/, *.db, *.local files
- SSRF protection: block private/loopback/link-local IPs by default
(UPTOP_ALLOW_PRIVATE_TARGETS=true to override for homelab use)
- Fix email header injection via CRLF in monitor names
- AES-256-GCM encryption for alert credentials at rest
(UPTOP_ENCRYPTION_KEY env var, migrate-secrets subcommand)
- TLS support for HTTP server (UPTOP_TLS_CERT/UPTOP_TLS_KEY)
with HSTS header when TLS enabled
Light theme doesn't work well on dark terminals. Replace with
two proven dark palettes. Now 5 themes: Flexoki Dark, Tokyo Night,
Catppuccin Mocha, Nord, Gruvbox.
Flexoki Dark (default), Flexoki Light, Catppuccin Mocha, Nord.
Press T to cycle themes; selection persists in preferences.
All hardcoded colors replaced with theme-driven values.
Dedicated ZebraBg per theme for subtle row striping.
Consistent with interval/timeout validators that already skip for
group monitors. Prevents potential validation block if field is
cleared while editing.
URL, SSL threshold, and port validators blocked form progression
when editing monitors that don't use those fields (e.g. ping monitors
failing URL validation, non-SSL sites failing threshold check).
Scope each validator to fire only for its relevant monitor type.
55 tests covering state machine transitions, heartbeat handling, push
deadline checks, group aggregation, history recording, probe aggregation,
log management, state management, and concurrency safety.
Checker tests cover HTTP (via httptest), port (via net.Listen),
isCodeAccepted ranges, and siteTimeout defaults. Ping and DNS
checkers skipped (need ICMP privileges and DNS server).
Coverage: 64.2% overall, 100% on handleStatusChange, triggerAlert,
checkPush, recordCheck, and AggregateStatus.
Monitors with the same interval no longer fire simultaneously.
Each tick adds up to 10% random jitter. Initial checks stagger
over 0-3s to avoid thundering herd on startup.
Replace string equality checks on cluster secret with
crypto/subtle.ConstantTimeCompare to prevent timing attacks.
Add http.MaxBytesReader (1MB) to all POST endpoints that decode
JSON bodies. Change Start() to return *http.Server for graceful
shutdown support. Replace log.Fatalf with log.Printf in HTTP
server goroutine.
Provider.Send now accepts context.Context for timeout/cancellation.
HTTPProvider and NtfyProvider use NewRequestWithContext so HTTP alerts
respect the 30s deadline. triggerAlert logs send failures and config
load errors instead of silently swallowing them.
generateToken() now returns (string, error) instead of panicking on
crypto/rand failure. All json.Unmarshal calls for alert settings now
check and propagate errors instead of silently ignoring them.
Adds Close() to Store interface for graceful shutdown support.
Skips malformed notification entries during Kuma import.
Site count in tab label and footer now reflects total monitors
(excluding groups) regardless of collapse state. Down count also
computed from all sites so collapsed groups with down children
still surface in the badge. Replaced Nerd Font folder glyphs
with standard Unicode triangles for cross-font compatibility.
Add alternating row backgrounds for easier table scanning. Detail panel
now shows breadcrumb path (Sites > Group > Name) and min/avg/max latency
stats below the sparkline. Group collapse state persists across restarts
via new preferences table in both SQLite and Postgres.
Group rows now show selection background when navigated to. Layout
chrome extracted to named constants to prevent viewport drift. Groups
display aggregate history as dot sparkline (●) distinct from site
bar sparklines, with uptime computed from active children only.
Paused and maintenance children excluded from group aggregates.
Group status now treats maintenance'd children like paused ones —
they're excluded from the UP/DOWN calculation. Prevents group from
showing DOWN when its only failing child is under maintenance.
Forms overflowed past terminal because huh didn't know about the
surrounding chrome (header, footer, padding). Now sets WithHeight()
on every render and forwards WindowSizeMsg during form state.
Maintenance windows suppress alerts during planned downtime while checks
continue running. Incidents provide informational tracking. Supports
targeting all monitors, single monitor, or group (applies to children).
New Maint tab in TUI with create/end/delete. Status page, JSON API, and
Prometheus metrics all reflect maintenance state.
The public status JSON endpoint was serializing full Site structs
including heartbeat tokens. An attacker could extract tokens and
forge heartbeats to suppress DOWN alerts. Now tokens are stripped
before encoding. Backup/export endpoint is unaffected.
Arrow-style icons per monitor type plus Nerd Font folder icons for
groups (closed when collapsed, open when expanded):
→ http, ↓ push, ↔ ping, ⊡ port, ◆ dns, / group
- DOWN/SSL EXP monitors float to top of sites list
- Pulse indicator turns red when any monitor is down, green when healthy
- Press / to filter sites by name, Enter to lock filter, Esc to clear
- Active filter shown in status bar
- Delete confirmation wrapped in rounded border box with danger color
- Empty sites view shows styled welcome box with onboarding hint
- NAME column width scales with terminal width (13-40 chars)
Polish pass for TUI professionalism:
- Status bar replaces generic footer with live stats (UP/DOWN count,
online probes) plus contextual key hints
- Tab badges show DOWN count on Sites tab and offline count on Nodes tab
- Detail panel (press i) shows full monitor info: URL, latency, uptime,
SSL, probe results, sparkline — without entering edit mode
Phase 3 of distributed probing:
- Add regions column to sites table for per-monitor probe affinity
- Region-filtered probe assignments (empty regions = all probes)
- New Nodes TUI tab showing connected probes with status/region/last-seen
- Regions input field in site form for configuring probe affinity
- Config-as-code support for regions (export/import/diff)
- Prometheus upkeep_probe_up metric with per-node labels
- Reindex TUI tabs: Sites, Alerts, Logs, Nodes, Users
Phase 2 of distributed probing:
- Extract check logic into standalone RunCheck() for use by probes
- Add probe cluster mode: stateless nodes that fetch assignments, execute
checks, and report results to the leader
- Add multi-node result aggregation with configurable strategy
(any-down, majority-down, all-down)
- Leader ingests probe results into engine live state and triggers alerts
- New env vars: UPKEEP_NODE_ID, UPKEEP_NODE_NAME, UPKEEP_NODE_REGION,
UPKEEP_AGG_STRATEGY
- Example docker-compose.probe.yml with leader + 2 regional probes
Add node-aware check history and probe registration infrastructure:
- ProbeNode model and nodes table (SQLite + Postgres)
- node_id column on check_history for multi-source tracking
- Store interface: RegisterNode, GetNode, GetAllNodes, DeleteNode, SaveCheckFromNode
- Dialect: UpsertNodeSQL (INSERT OR REPLACE / ON CONFLICT)
- API endpoints: POST /api/probe/register, GET /api/probe/assignments, POST /api/probe/results
- Backward compatible: existing SaveCheck wraps SaveCheckFromNode with empty node_id
Add declarative config-as-code support via YAML files. Monitors and
alerts can be exported, version controlled, and applied across instances.
- goupkeep export [-o file.yaml] dumps current state
- goupkeep apply -f file.yaml creates/updates to match desired state
- --dry-run shows planned changes without applying
- --prune deletes monitors/alerts not in the YAML
- Matching by name, alert references by name, nested group children
- CLI refactored to subcommands (apply, export, serve) with backward compat
- 24 tests covering apply, export, validation, round-trip idempotency
DB fields existed but were never surfaced in the TUI. Adds an HTTP
Settings form group with method select (7 methods) and accepted
codes input, visible only for HTTP monitors.
Expand alert provider count from 5 to 9. All new providers use
the shared HTTPProvider with closure-based payload functions.
Includes TUI form support and tests for each provider.
Replace all monitor package-level mutable state with Engine struct.
All state (liveState, logStore, histories, tokenIndex, HTTP clients)
is now encapsulated in Engine, created via NewEngine(store).
Key changes:
- Engine struct holds all monitor state with proper mutex protection
- Engine.Start(ctx) and monitorRoutine respect context cancellation
for graceful shutdown — no more leaked goroutines
- cluster.runFollowerLoop also respects context for clean exit
- Token index (map[string]int) for O(1) push heartbeat lookup,
replacing O(n) linear scan through LiveState
- UpdateSiteConfig preserves 8 runtime fields instead of copying
17 config fields individually
- triggerAlert goroutines get 30s timeout context
- All consumers (TUI, server, cluster, main) receive *Engine via
constructor/parameter — no package-level state access
- main.go creates context.WithCancel, passes to engine and cluster
First test suite: 12 tests across store and alert packages
- Store: CRUD for sites/alerts/users, push token generation,
import/export round-trip, check history persistence
- Alert: Discord/Slack/Webhook payload format, HTTP 4xx error
propagation, Ntfy headers, unknown provider returns nil
- New table_helpers.go with renderTable() and shared styles
- Remove 4 duplicated style blocks (header/cell/selected/border)
from tab_alerts.go and tab_users.go
- All 3 tab views now use renderTable() for offset/end calc,
selected row highlighting, and table construction
- Sites tab keeps siteGroupStyle via StyleOverride callback
- Clamp cursor to list length at end of refreshData() to prevent
index-out-of-bounds after concurrent list changes
- Fix off-by-one in tab click handler (i <= maxTabs → i < tabCount)
Discord, Slack, and Webhook providers now use a single HTTPProvider
struct with a PayloadFunc for the only part that differs. Centralizes
response body handling and adds HTTP status code checking (4xx/5xx
now return errors instead of being silently ignored).
Email and Ntfy keep separate implementations (different protocols).
Adding a new HTTP-based alert provider is now a one-line PayloadFunc.
