Replace 3-tab navigation with a single monitoring dashboard.
- Replace tab bar with minimal status line (pulse + counts + version)
- Maintenance becomes a toggleable left sidebar (m key)
- Compact list: active (●) and scheduled (○) windows
- Enter opens full-screen detail with end/delete actions
- Settings becomes a centered floating overlay (S key)
- Alerts/Nodes/Users sub-sections with left/right navigation
- Full CRUD support inside overlay with returnState tracking
- Remove currentTab, switchTab, tab constants, tab click zones
- Replace deleteTab with deleteKind string for cleaner dispatch
- Separate settingsCursor/settingsOffset from main cursor
- Panel focus: maint → monitors → logs → detail
- Context-sensitive footer key hints per focused panel
- Hide nonsense latency/histogram data for group monitors in detail view
- Add missing status colors to fmtStatusWord (LATE, STALE, PENDING, etc)
- Wrap Maint and Settings tabs in titled panels to match Monitors tab
- Standardize headers: breadcrumb style (History > Name, SLA > Name)
- Standardize footer key order: actions first, [q/Esc] Back last
- Add # column to Nodes table for consistency with all other tables
- Use titleStyle for section headers (CONFIGURATION, DAILY BREAKDOWN)
- Fix panel focus not switching when clicking monitor rows from logs panel
Show a detail line below the alert table for the selected row
with untruncated config, health status, last sent time, and
send/fail counts. Solves the CONFIG column truncation issue
without requiring the full-screen detail view.
Thread context.Context from callers instead of creating
context.Background() at every call site. Engine stores its
lifecycle ctx for use by triggerAlert goroutines. TUI Model
carries ctx for store operations in Cmd closures. CLI commands
create a root ctx and thread it through openStore, seed
functions, and init methods.
Only two intentional context.Background() remain in non-root
positions: engine constructor default (overridden by Start)
and drainWrites (parent already cancelled at shutdown).
1. Rate limiter cleanup goroutine now stoppable via Stop() channel
instead of looping forever. Prevents goroutine leak in tests.
2. Dead WindowSizeMsg branch in handleFormMsg removed — top-level
Update handles resize before forms see it.
3. Probe results sorted by node ID — map iteration no longer
reorders rows every render.
4. fmtAlertConfig takes models.AlertConfig directly instead of an
anonymous struct the caller builds inline.
5. Backspace no longer aliases delete — d is the documented key.
Prevents accidental delete-confirm on habitual backspace.
6. SLA daily buckets use time.Date day arithmetic instead of
Add(-i*24h) — lands on midnight correctly across DST transitions.
Cursor tracked by site ID instead of positional index. When the
list re-sorts every tick (sites change status), the selection stays
on the same monitor instead of silently jumping to whatever now
occupies that index position.
q now means "back" in detail, history, SLA, and alert-detail views
— consistent with muscle memory from navigating deeper views.
Only the dashboard q quits the app. ctrl+c always quits from
anywhere.
Every Store interface method (except Close) now takes context.Context
as first parameter. All 54 db.Query/Exec/QueryRow calls in SQLStore
replaced with their *Context variants. DB operations now respect
cancellation and deadlines.
Context sources by caller:
- Engine dbWriter/poll/pruner: engine ctx from Start()
- HTTP handlers: r.Context()
- config.Apply/Export: caller-provided ctx
- TUI/main.go init: context.Background()
RunCheck and all sub-checks (HTTP/ping/port/DNS) accept parent ctx.
HTTP checks now inherit shutdown cancellation instead of rooting in
context.Background(). dbWrite.exec takes ctx so the writer goroutine
can cancel stuck DB operations.
DeleteSite/ImportData use BeginTx(ctx) instead of Begin().
The alert detail panel dumped a.Settings raw — SMTP passwords, bot
tokens, API keys on screen and into any recording or screen share. The
table view leaked the PagerDuty routing key, Pushover user key, and
full discord/slack/webhook URLs (the URL path is the credential).
The redaction allowlist moves from internal/server to
models.RedactAlertSettings so the backup export and the TUI render
through one policy. Panel keys are sorted so rows stop reshuffling
every tick; webhook URLs show scheme+host only; keys show
first4…last4.
Deletes, pause toggles, maintenance end, theme/collapse prefs, and all
four form submits wrote to the store synchronously on the UI goroutine;
with busy_timeout=5000 a contended DB froze input for up to 5s.
Writes now run through a writeCmd helper returning writeDoneMsg. The
in-memory engine/model mutations stay in Update so rows react
instantly; the reply logs failures and reloads tab data, so the UI
converges on what was actually written. Closures capture snapshotted
values only — never the model.
applyTheme mutated ~18 package-global lipgloss styles while every SSH
session's tea.Program read them concurrently from its own goroutine.
Pressing T or opening a new connection raced other sessions' View and
bled themes across users.
Styles now live in an immutable per-Model struct built by newStyles;
free formatter helpers that consumed the globals became Model methods.
- STATUS column shows icon + clean state only (▲ UP, ▼ DOWN, ◆ LATE,
◆ STALE, ◇ PAUSED, ◼ MAINT, ○ PENDING). Error classification
(DNS/TLS/TMO) removed from STATUS — stays in NAME inline hint.
- Detail panel Last Check shows relative time ("12s ago") instead of
absolute timestamp.
- Extract shared fmtTimeAgo() to format.go, consolidate duplicate
formatters in tab_alerts.go and tab_nodes.go.
- Extract divider() and emptyState() helpers to format.go
- All empty states now use bordered box with accent color
- Detail and alert detail panels get header/section dividers
- SLA label width 14→16 to match detail/alert panels
- Logs key hints moved from content to dashboard footer
- History/SLA panels use shared divider helper
Support Opsgenie Alert API v2 with US/EU endpoint selection,
configurable priority (P1-P5), and GenieKey auth. TUI form
includes API key, priority picker, and EU instance toggle.
Move Go module from gitea.lerkolabs.com/lerko/uptop to
gitea.lerkolabs.com/lerkolabs/uptop. Updates all imports,
go.mod, goreleaser owner, and README links.
Track alert delivery health at runtime:
- AlertHealth struct: LastSendAt, LastSendOK, LastError, SendCount, FailCount
- triggerAlert records success/failure after each Send()
- Health data exposed via GetAlertHealth() for TUI
Alerts tab enriched:
- Health dot column: green (OK), red (failed), gray (never sent)
- LAST SENT column: relative time ("2m ago", "never")
- [t] key sends test notification through selected channel
Inspired by Grafana's contact point health columns.
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.
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)
Remove store.Get()/SetGlobal()/Current. Store is now passed explicitly
to all consumers via constructor parameters and function arguments.
- TUI Model holds store field, set via InitialModel(isAdmin, store)
- monitor.StartEngine(s) and InitHistoryFromStore(s) accept store
- server.Start(cfg, s) closes over store in HTTP handlers
- main.go threads store to SSH server, TUI, monitor, server
- isKeyAllowed receives store as parameter
No more hidden dependency on package-level mutable state in store pkg.
Monitor package still uses package-level state (LiveState, etc.) — will
be encapsulated into Engine struct in Phase 7.
Every Store method now returns an error. Callers handle errors
gracefully — TUI logs to event log, server returns HTTP 500,
monitor engine logs and retries. All rows.Scan() errors are now
checked in sqlstore.go instead of silently appending corrupt data.
- GetSites, GetAllAlerts, GetAllUsers return ([]T, error)
- GetAlert returns (AlertConfig, error) instead of (AlertConfig, bool)
- AddSite, UpdateSite, DeleteSite, etc. all return error
- SaveCheck, LoadAllHistory, ExportData return error
- ~25 caller sites updated across tui, server, monitor, main
Per-site pause: [p] key toggles pause for selected monitor in TUI.
Paused monitors skip checks, persist to DB, show on status page.
Status page: replace full-page reload with fetch-based DOM updates
to eliminate scroll-jump on refresh. Add summary bar (UP/DOWN/PAUSED
counts), stale-data indicator, and fix SSL EXP CSS class bug.
TUI: constrain tables to terminal width via lipgloss .Width() to
prevent row wrapping that pushed header off-screen. Add MaxHeight
safety net. Bump subtle style from #383838 to #565f89 for
readability on dark terminals.
POST to ntfy server/topic with title, priority, and optional basic auth.
TUI alert form includes ntfy type with server URL, topic, priority
selector (1-5), and credential fields.
