TUI Guide

The bewitch TUI provides 8 views for real-time system monitoring with historical charts.

Views🔗

Views are accessed via number keys. Tab numbering is fixed regardless of hardware availability.

KeyViewDescription
1DashboardMulti-column overview of all subsystems
2CPUPer-core usage with historical chart
3MemoryRAM and swap breakdown with history
4DiskPer-mount space, I/O rates, SMART health
5NetworkPer-interface throughput with bits/bytes toggle
6HardwareTemperature, power (RAPL), ECC memory, and GPU sub-sections
7ProcessAll processes, sortable, searchable, pinnable
8AlertsAlert rules and fired alerts

Network View🔗

Per-interface throughput with sparklines and historical chart. Select which interfaces appear on the chart.

KeyAction
j / kNavigate interface list
SpaceToggle interface in chart
aSelect / deselect all
bToggle bits/bytes display

Hardware View🔗

The Hardware view combines temperature sensors, power consumption (RAPL), ECC memory errors, and GPU metrics into sub-sections. Use Tab / Shift+Tab to cycle between sub-sections. Sections without data are dimmed but still accessible. The active sub-section is persisted across sessions.

KeyAction
Tab / Shift+TabCycle sub-sections (Temperature, Power, ECC, GPU)
j / kNavigate sensor/zone list
SpaceToggle sensor/zone in chart
aSelect / deselect all

Process View🔗

Shows all processes on the system. Non-enriched processes display -- for cmdline and FD count. The history chart shows top N processes by CPU over time.

KeyAction
j / kNavigate process list
cSort by CPU
mSort by memory
pSort by PID
nSort by name
tSort by threads
fSort by FDs
*Pin/unpin selected process
aCreate alert for selected process
/Search by name or cmdline
EscClear search filter
PToggle pinned-only filter
TabToggle history chart: Top CPU / Pinned

Alerts View🔗

Two panels: a rules list on the left and fired alerts on the right. Create, toggle, and delete rules directly from the TUI.

KeyAction
j / kNavigate rules or alerts
TabSwitch focus between rules and alerts
nCreate new alert rule
dDelete selected rule
SpaceToggle rule enabled/disabled
EnterAcknowledge selected alert
tTest all notification channels
EscCancel alert creation form

Historical Charts🔗

CPU, memory, disk, hardware (temperature/power/GPU), and process views include a historical braille chart below the live data. Use < / > to cycle through time ranges: 1h, 6h, 24h, 7d, 30d.

Bucket size auto-scales based on the selected range (1 minute for 1h up to 6 hours for 30d). History data is fetched asynchronously and cached per-view for instant display on tab switch.

Staleness Detection🔗

The status bar monitors when fresh data last arrived for the current view. If no new data appears within 3x the longest collector interval for that view, a stale indicator shows: stale (Xs ago).

Debug Mode🔗

bewitch -debug

Adds a scrollable debug console at the bottom of the TUI showing timestamped diagnostic messages: data fetches, cache hits/misses, view transitions, errors, and pin operations.

KeyAction
{ / }Scroll debug console up / down
( / )Shrink / grow debug panel

Layout🔗

The dashboard adapts to a multi-column grid layout on terminals wider than 120 columns.
