SLA daily breakdown no longer overflows past the monitors panel. Detail
sidebar height is capped to monitors panel height via titledPanelH.
SLA daily rows are limited to fit within available space. Logs strip
stays visible in all detail modes.
Enter now toggles detail sidebar open/closed with preference
persistence. Removes redundant i keybind that did the same thing.
Hotbar updated: [Enter]Detail when closed, [Enter]Close when open.
Enter now consistently opens the detail sidebar for both monitors and
groups. Group collapse/expand is Space-only. Hotbar shows [Space]Expand
or [Space]Collapse contextually when cursor is on a group row.
All monitor detail content now lives in the sidebar panel.
Delete the full-page viewDetailPanel, viewSLAPanel, viewHistoryPanel,
handleDetailKey, handleSLAKey, handleHistoryKey, openSLAView, and
related dead code (histogram, sparkline tooltip, detailViewport).
Remove stateDetail, stateSLA, stateHistory session states.
Update tests to use detailOpen/detailMode instead of removed states.
Enter on a site now opens the detail sidebar instead of a
full-page takeover. Enter on a group expands/collapses children
(same as space). Logs panel moves to a toggleable bottom strip
via the l key with j/k scrolling when focused.
SLA and History views now render inside the detail sidebar panel
instead of taking over the full screen. Press s/h to switch modes,
Esc to return to default detail view. Cursor movement resets to
default mode.
- Add detailMode state (detailDefault/detailSLA/detailHistory)
- SLA sidebar: period selector, uptime bars, daily breakdown
- History sidebar: sparkline density, transition list, stats
- Panel title shows "SLA · name" or "History · name" in sub-modes
- Period keys [1]-[4] work in SLA mode from dashboard state
Replace the old two-column/single-column inline detail with a
vertically stacked layout optimized for the right-side panel.
Content stack: status line, type details, uptime, error, latency
chart (3-row), 30d timeline, sparkline, min/avg/max stats, and
up to 5 state changes — all flowing top-to-bottom within the
~55% width detail panel.
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
Delete confirmation dialog used wrong magic numbers for entity kind
mapping — maintenance windows showed as "alert", settings deletions
showed as "monitor". Now uses tab/section constants to match correctly.
Also: consistent [q/Esc] Back across all views (detail inline, logs,
SLA, history headers), extract detailKeys(), remove dead maxSections
variable, add nodes empty state hint, use models.Status constants in
siteOrder, delete orphaned theme.png.
- Click Alerts/Nodes/Users sub-tabs in settings to switch sections
- Click STATUS/NAME/LATENCY column headers to sort (click again
to reverse direction)
- Logs panel show/hide: [l] toggles sidebar visibility, click
focused panel to hide. Monitors expand to full width when hidden.
- Logs full-screen: Enter when focused on logs opens scrollable
full-screen log view with severity tags, filter toggle [f],
and live updates
Move refreshMaintenanceCache() to after sites are loaded into
liveState. Previously it ran before the site loading loop, so on
the first iteration liveState was empty and the cache resolved
to nothing. This caused groups to briefly show DOWN on startup
for children that were in maintenance, until the next poll cycle
repopulated the cache.
checkGroup() now detects status transitions and persists them as
state change records, same as individual monitors. Groups also
get StatusChangedAt updates and log entries for down/recovery
events. This enables history and SLA views for group monitors.
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.
Redesign the inline detail panel from a single left-aligned column
to a two-column layout that uses the full panel width.
Left column (55%): latency chart, min/avg/max stats, 30-day
uptime timeline.
Right column (45%): status/latency/last-check summary, type-
specific metadata (HTTP response code + SSL expiry, ping hostname,
port target, push interval/last heartbeat, DNS resolver), uptime
percentage + retry count, and up to 5 state changes listed
vertically with error reasons.
Narrow terminals (<80 cols) fall back to the original stacked
single-column layout.
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).
Split monitor.go (1131→350 lines) into alerts.go, checks.go,
sites.go, and maintenance.go by concern. Split sqlstore.go
(833→470 lines) into sqlstore_alerts.go, sqlstore_history.go,
and sqlstore_maintenance.go by domain. Tests move with their
implementation. Pure reorganization — no behavioral changes.
Replace inline numeric literals with named constants across 14 files:
server timeouts/rate limits, cluster thresholds/intervals, DB pool
sizes, alert/dial timeouts, TUI uptime thresholds, node status
thresholds, and state history limits.
Warn via log when creating a maintenance window that overlaps with an
existing one for the same monitor, parent group, or global scope.
Handles both timed and indefinite windows.
Bottom section: graphs (latency + histogram) 70% left, state changes
30% right. Top section rearranged: endpoint details left, status +
timing + HTTP right. Bottom section labels use bold accent without
trailing rules. Spacing between top and bottom halves.
Removed unused renderSparkTooltip (zone marks not wired in column
layout — can restore later).
Section labels (STATE CHANGES, LATENCY, RESPONSE TIME DISTRIBUTION,
PROBE RESULTS) now render in bold accent color with a trailing ───
rule that fills the width. Two-column info block separated by a full
divider below. Creates clear visual boundaries between sections.
Refactored full-screen detail panel: status+endpoint on left column,
timing+config on right column. Halves vertical height of the info
section. Content wraps in a viewport when it exceeds terminal height
— scroll with j/k/arrows/pgup/pgdn.
Restored renderSparkTooltip lost in rewrite. Fixed lint warnings.
Horizontal bar chart showing latency distribution across 5 buckets:
0-50ms, 50-100ms, 100-200ms, 200-500ms, 500ms+. Color-coded green
(fast), yellow (medium), red (slow). Shows count per bucket.
Appears in the full-screen detail panel (Enter) after the sparkline
stats. Skipped for push monitors (no latency data).
Statuspage-style colored bar — one █ per day, colored by uptime:
green (>= 99%), yellow (>= 95%), red (< 95%), gray (no data).
30-day percentage shown to the right.
Daily breakdown computed via ComputeDailyBreakdown from state_changes
and loaded alongside detail data in loadDetailCmd. Auto-updates on
cursor move.
Settings tab warn count now includes failed alert channels — alerts
where the last send failed (LastSendOK=false, LastSendAt not zero).
Shows as a red badge number alongside offline node count. Surfaces
broken alert channels without navigating to Settings.
Press < / > to cycle sort column (Status, Name, Latency). Press r to
reverse direction. Sorted column shows ▲/▼ arrow in the header.
Groups always float to top. Sort applies to ungrouped monitors and
group children independently. Default: Status descending (DOWN first).
Replace ntcharts with custom multi-row sparkline. Each bar is color-
coded by latency threshold (green < 200ms, yellow < 500ms, red > 500ms)
and DOWN checks render in red. 3 rows tall with 24 discrete levels.
Y-axis labels (max/min ms) on the left, Min/Avg/Max stats below.
Zero external dependencies — removed ntcharts.
Replaced streamline chart with ntcharts sparkline (block elements,
auto-scaling). Height=2, Y-axis labels (max/min ms) on the left,
Min/Avg/Max stats below. Denser and more readable than the line chart.
Replace block-element sparkline with ntcharts streamline chart in the
inline detail panel. Renders a 4-row line chart with thin line style
using the theme accent color. Auto-scales Y axis to latency range.
Added github.com/NimbleMarkets/ntcharts v0.5.1 dependency (lipgloss v1
compatible). Min/Avg/Max stats rendered below the chart.
Introduced models.LogEntry{Message, CreatedAt} to replace raw strings
in the log pipeline. Timestamps are now formatted at render time, not
baked into stored messages.
- Engine: appendLog stores LogEntry with time.Now()
- Store: LoadLogs returns []LogEntry, selects created_at from DB
- Store: strips legacy [HH:MM] prefix from pre-refactor DB entries
- TUI: sidebar shows "MM/DD HH:MM" from CreatedAt
- TUI: full log view shows "MM/DD HH:MM" from CreatedAt
- SaveLog still receives plain message string (DB handles timestamp)
Detail open/closed state saved via SetPreference on toggle and
restored on session start. Same pattern as theme persistence —
survives restarts and works per-user over SSH.
Click any panel (Monitors, Logs, Detail) to focus it — accent border
follows focus. Mouse wheel scrolls the focused panel.
Keyboard: l toggles log panel focus. Arrow keys scroll logs when
focused, navigate monitors when not. Esc returns focus to monitors.
Log sidebar now supports scroll offset — tracks position across
renders without a viewport. Mouse wheel scrolls 3 lines, keyboard
scrolls 1.
All panels wrapped in titled rounded borders (╭─ Title ──╮). Focused
panel gets accent-colored border, unfocused panels get muted border.
- Monitors panel: titled "Monitors", focused when detail is closed
- Logs panel: titled "Logs", always unfocused (passive display)
- Detail panel: titled with monitor name, focused when open
Table's own RoundedBorder replaced with HiddenBorder — the titled
panel border provides the visual frame, table uses space-separated
columns internally. Consistent chrome across all panels.
Log sidebar wrapped in rounded border (no left/bottom edge — shared
with monitors table). Creates visual separation between panels.
Enter on a monitor opens the full-screen detail view (existing
stateDetail) for deep dive — history, SLA, probe results, connection
chain. i stays as inline detail toggle.
Footer key hints now context-sensitive: show h/s/Enter when detail
is open, show full keybindings when closed.
Log sidebar was rendering all lines regardless of table height. When
detail panel was open and table shrank, the sidebar stayed tall, pushing
the detail panel past MaxHeight (clipped to empty). Now sidebar accepts
a maxLines parameter capped to table row count.
Press i to toggle a compact detail panel below the monitors+logs
split. Shows status, latency, uptime, state changes, sparkline, and
key hints in ~6 lines. Auto-updates when cursor moves between
monitors. h/s/e keys work from the inline detail for history, SLA,
and edit. Escape closes the panel.
No more full-screen detail takeover for the common case. The old
stateDetail path remains for h/s sub-views which still go full-screen.
Log lines now hard-clamped to panel width via lipgloss MaxWidth.
Stripped "Monitor " and "Push " prefixes from sidebar messages —
redundant in a monitoring app, saves 8 chars per line. Improved
prefix width calculation to prevent line wrapping at narrow widths.
Table columns were computed from terminal width, causing row wrapping
when the monitors panel only gets 70% of the space. Introduced
contentWidth field set per-tab in viewDashboard. computeLayout,
isWide, and renderTable now use contentWidth for column visibility,
available space, and max table width calculations.
Columns gracefully hide (SSL, RETRIES, TYPE, UPTIME) when the panel
is narrower, matching the existing responsive breakpoint behavior.
