terdut-tui

A terminal user interface for terdut-server. Communicates with the server over its REST API.

Written in Go using Bubbletea.

Features

• Incident queue — open incidents with severity, status, assignee and age, auto-refreshing
• Incident actions — acknowledge, assign, snooze, note, resolve and archive
• Timeline — the full history of an incident, system events, pages and notes together
• Alert feed — the raw read-only alerts underneath, each linked to its incident
• Teams — switch between your teams, or see all of them at once
• On-call schedule — visual calendar of who is on duty in a team, assign and remove entries
• Statistics — MTTA and MTTR, plus alert frequency by name, hour and day
• User management — add and remove users, manage API keys, set each user's ntfy topic

Requires terdut-server v0.20.0 or later. The server became team-scoped in v0.12 and this client follows it; earlier servers answer 404 for /api/teams and the TUI says so on start. Use terdut-tui v0.9.x with servers before v0.12. Escalation ladders, invites, integrations and the admin settings stay in the server's web UI.

Teams

Everything the server returns is scoped to the teams your key's user belongs to. The header shows which are on screen, and T steps through all → each of your teams in turn. With several teams showing, incident and alert rows carry a Team column.

The schedule is one team's rota, so the Schedule section shows the active team, or with all showing the first team you own. Only a team's owners, and administrators, can change its rota; anyone else gets the reason in the status bar instead of a picker. The picker offers only that team's members, because the server refuses anybody else. Stats are not team-scoped by the server and always cover all your teams.

Administrators are the only users who can create or delete users, or act on someone else's password, topic or API keys. Everyone can manage their own.

Alerts and incidents

The server keeps two objects and this client follows that split:

• An alert is Alertmanager's record — firing or resolved, and read-only here.
• An incident is the work item. It is what you acknowledge, assign, snooze, discuss and resolve, and it is where all the actions live.

Incidents are correlated by the groupKey Alertmanager already computed from your group_by configuration, so several alerts commonly share one incident.

Two behaviours worth knowing before you press a key:

• Resolving is final. The server treats a manual resolve as terminal: a later occurrence opens a new incident rather than reopening this one, and if the alert underneath never stops firing the incident stays closed. The TUI asks for confirmation before doing it.
• Snooze is the "not now" button. It hides an incident from the default queue without closing it, and expires on its own.

Push notifications

When the server is configured for ntfy, an incident that opens pages whoever is on call. Each user has their own topic, shown as a column in the Users section and edited with t. A user with no topic falls back to the server's shared fallback topic, which carries no Acknowledge button — the topic is shared, so a button on it would let any subscriber acknowledge as somebody else.

Every delivery lands on the incident's timeline: Notified <user> (triggered) when ntfy accepted the page, and Notification to <user> failed when it ran out of retries. That second one is the one to look for when nobody's phone rang.

Installation

Download the latest release binary for your platform from the releases page, or build from source:

go install git.ryuvia.com/niklas/terdut-tui@latest

Configuration

Create ~/.config/terdut-tui/config.yaml:

server_url: https://terdut.example.com
api_key: <your-api-key>
refresh_interval: 30  # seconds, optional
theme: gruvbox-dark   # optional, this is the default
team: Ops             # optional, a team name or id to start on; default is all

The API key is generated in terdut-server. See the server documentation for how to bootstrap a user and issue an API key.

Themes

Two themes ship with the client: gruvbox-dark (the default) and gruvbox-light. Both colour foregrounds only — the terminal supplies the background — so pick the one that matches the background you already run.

To make your own, drop a file in ~/.config/terdut-tui/themes/ and name it in theme:. extends inherits a built-in, so a file only has to list what it changes:

# ~/.config/terdut-tui/themes/mine.yaml
extends: gruvbox-dark
primary: "#d3869b"
accent: "#fabd2f"

A file may shadow a built-in name — themes/gruvbox-dark.yaml is how you tweak the default without renaming it.

Without extends, every token must be set. The twelve are:

Token	Where it shows
primary	header, active tab, selected row, cursors
on_primary	text drawn on primary — the active tab and selected row
text	incident titles and other emphasis
muted	secondary text, dividers, footer, table headers
accent	status line, acknowledged incidents, the by-day chart
firing	firing alerts, triggered incidents, the by-hour chart
resolved	resolved alerts and incidents, the top-alerts chart
error	error banners
sev_critical, sev_error, sev_warning, sev_info	the severity label

Values are hex (#83a598 or #abc) or an ANSI palette index (0–255) if you would rather follow your terminal's own colours. Colours are downsampled automatically on 256- and 16-colour terminals, and NO_COLOR is honoured.

Usage

terdut-tui                 start the TUI
terdut-tui --version       print version
terdut-tui --self-update   update to the latest release

Keybindings

Global:

Key	Action
j / ↓	Move down
k / ↑	Move up
tab / shift+tab	Next / previous section
enter	Open detail
esc	Go back
r	Refresh
f	Cycle filter
T	Switch team: all → each of your teams (when you have more than one)
q	Quit

The sections, in tab order: Incidents · Alerts · Stats · Archived · Schedule · Users.

Incidents section:

Key	Action
f	Cycle: open → triggered → acknowledged → resolved → snoozed
x	Archive (resolved incidents only)

Incident detail:

Key	Action
a / A	Acknowledge / clear acknowledgement
R	Resolve — asks to confirm, and is final
s	Assign to a user
z / Z	Snooze for a duration / un-snooze
c	Add a note
[ / ]	Select a note
d	Delete the selected note (your own only)
x	Archive / un-archive

Alerts section (read-only):

Key	Action
f	Cycle: firing → resolved → all → archived
i	In detail: jump to the alert's incident

Stats section:

Key	Action
j / k, pgup / pgdn	Scroll

Schedule section:

Key	Action
+ / W	Assign a day / a whole week
d	Remove the assignment
← / →	Shift the week window

One person holds a given day. Assigning over days somebody else already has asks first — naming them and how many days are being taken — and moves the whole selection at once when you accept, so reassigning a week is one confirmation rather than seven deletions. The header line names the team whose rota this is, and "On-call today" lists everyone on call across your teams.

Users section:

Key	Action
n	Create a user
t	Edit the user's ntfy topic — submit empty to clear it
d	Delete a user
k	API keys for the selected user
p	Set the selected user's web UI password — asks for the current one when it is your own

In Users, k and d act on the selected row, so move with ↑/↓ there rather than k. The Flags column marks administrators and disabled accounts. n and d are for administrators; t, k and p work on your own row, or on anyone's if you are one.
