Replace O(windows × sites) isMonitorInMaintenance with O(1) map lookup.
buildMaintSet runs once per refreshLive/handleTabData, not per call site.
groupSparkline/groupUptime now use m.sites (already on model) instead of
calling engine.GetAllSites() which copies the full map under a mutex.
Match the sidebar's bordered panel style (╭─ Title ─╮) so the
fullscreen detail view on narrow terminals looks cohesive with the
rest of the UI. Breadcrumb now renders as the panel title.
Drop the row-number column and add a colored status dot as the first
column. Dot uses the same icon/color as the existing status indicators
(▲ green for up, ▼ red for down, ◼ purple for maint, etc). Matches
the maint strip visual pattern. Status text column retained for
explicit label.
Monitors panel now uses titledPanelH with a target height based on
maxTableRows, filling the space down to the bottom strip. No more
gap between monitors panel and logs/maint strip when fewer monitors
than available rows.
Use panel zone Pos() to compute clicked row from Y offset instead of
per-cell zone matching. Monitors and maint strip both support full-row
click selection.
Replace the cramped 22-char maint sidebar with a full-width bottom
strip in the same position as logs. Bottom panel is modal: l for logs,
m for maint, same key again to close. Maint strip shows one row per
window with icon, title, affected monitors, and status/time remaining.
Removes maintSidebarW constant and maintOffset field. Introduces
bottomPanel enum (bottomNone/bottomLogs/bottomMaint) replacing
logsOpen and maintOpen booleans. m key no longer gated behind
wideBreakpoint.
Footer keys (period selector, edit/history/SLA shortcuts, Esc) are now
pinned at the bottom of the detail panel, always visible regardless of
scroll position. Scrollable content fills the space between the header
and the pinned footer.
Detail sidebar now maintains consistent height matching the monitors
panel across all modes (default, SLA, history). Content scrolls within
the fixed frame via mouse wheel or j/k when the detail panel is
focused. Scroll offset resets on mode/monitor/period changes. Logs
strip stays visible in all states.
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.
