stroblme 5d0ea480bf Alerts: a Telegram channel, one chat or group each, connected by a one-time link
The channel sends through the Bot API with httpx only: HTML with escaped text,
cut to fit a message, silent for a warning, a short 429 waited out once, and
errors that say what to do about a blocked bot, a lost chat or a bad token and
never quote the request URL. The bot token is a stored secret: saving a
channel refuses a literal one, the card's "Store token" writes the secret and
a reference, and no endpoint returns it.

A chat id is never typed. Connect starts a ten minute code, and the chat that
sends `/start <code>` back through the bot is the one connected, so it is a
chat somebody opened a link for. The engine fetches updates only while a code
is waiting (no standing poll, no webhook, no inbound address) and ignores
everything else without a reply. Connect needs a saved form, and the form
takes the connected chat in without touching what was typed since.

The token is part of every Bot API URL, so the httpx logger gets the same
filter the request lines have, which now also masks an httpx.URL argument.

# Secrets, modules and alerts
Store credentials, manage node dependencies and choose where failures go.
These screens help keep an instance humming.
## Secrets
Open **Secrets** as a superuser, then add a name and value. The list shows
names only; saved values are not displayed again.
Reference a secret from a node setting:
```json
{"$secret": "influx-token"}
```
Fluksio resolves it when building the node. Credential fields in the editor
offer a secret picker. Missing names produce an error on the affected node.
Secrets are encrypted with a key derived from `SECRET_KEY` and stored outside
the flow repository. Using references keeps credentials out of saved flows.
!!! warning "Keep your encryption key"
Changing `SECRET_KEY` makes existing secrets unreadable. Keep the old key
for re-encryption, or re-enter the secrets. Source installations include
`backend/scripts/rotate_secret_key.py` for rotating the secrets store.
## Modules
**Modules** shows the Python environment used by node code, its installed
packages and Python version. There are two setups:
- **Managed environment:** Docker uses a separate node environment. A
superuser edits **Requirements** and presses **Apply**. The list is resolved
with `uv pip compile` and synced with `uv pip sync`, so each package brings
its dependencies and deleting a requirement removes it. The manifest is
versioned with the flows, and successful installs refresh the workers.
- **Adopted environment:** a fresh pip installation inside your own virtual
environment can use that environment for nodes too. Modules is read-only.
Install dependencies there with pip or uv, then sync or restart Fluksio.
Set `NODE_VENV=managed` to request a separate environment. Installation
failures show the package manager's output on the page.
For an existing scientific environment on another machine, attach a worker
with `fluksio-worker --python /path/to/venv/bin/python`. See
[Remote workers](../code/workers.md).
## Alerts
Create a channel, choose events in a rule, and use **Test** to check delivery.
Enable alerts for the rules to send. Channels and rules belong to superusers,
whose Alerts page holds them. Any other account sees only the button that
subscribes its own browser to a **webpush** channel.
### Channels
| Kind | Destination |
|---|---|
| **ntfy** | server and topic; optional token |
| **SMTP** | recipient address, using the instance's mail settings |
| **Webhook** | URL that receives a POST |
| **Dashboard** | declared message read by a Notification widget |
| **webpush** | browsers subscribed from the Alerts page |
| **Telegram** | one chat or group, connected from the Alerts page through a bot of your own |
Channel settings may use `{"$secret": "name"}` references. Browser push also
needs notification permission and a secure browser context.
### Telegram
Create a bot with @BotFather and copy its token. Add a **telegram** channel,
paste the token under **Bot token**, press **Store token**, then **Save**. The
token goes to the secrets store and the channel keeps only a reference, which
is the one form the API accepts.
Press **Connect**, open the link in Telegram on the device that should get the
alerts and press Start. **Add to a group** connects a group instead, and
everyone in it reads the alerts. The link works once and runs out after ten
minutes. A chat id is never typed in: the chat that sends the link's code back
is the one connected.
One channel is one chat. To send different events to different people, make
a channel for each and choose them in the rules. A warning arrives without a
sound. If the chat blocks or removes the bot, **Test** and the log say so;
press **Reconnect**.
The engine asks Telegram for updates only while a link is waiting, so it needs
no public address, and anything else sent to the bot is ignored without a
reply. Telegram lets one program fetch a bot's updates at a time, so give each
instance a bot of its own. Starting from a group sends `/start@bot code`;
whether a group in Telegram's default privacy mode delivers it has not been
tried against a live bot, so press **Test** after connecting one.
### Rules
A rule selects events and destination channels. Leaving all events unchecked
matches every supported alert event, including future additions.
| Event | Trigger |
|---|---|
| `node_error` | a node fails |
| `node_health` | a connection goes down |
| `flow_quarantined` | repeated crashes stop a flow's background work |
| `task_crashed` | a background task crashes |
| `engine_degraded` | engine health degrades |
| `cascade_dropped` | the engine drops work |
| `queue_unavailable` | the work queue becomes unreachable |
| `run_finished` | a batch run ends in error |
Repeated faults are deduplicated with a 15-minute default cooldown. The
engine remembers what it sent in its database, so a restart does not start
every cooldown over, and the ten-per-hour cap holds across one too. Cooldowns
longer than seven days are not kept. A `node_health` alert waits until the
connection has been down for a minute, so a broker that restarts with the
stack or a device that reconnects alerts nobody. Flapping connections are
suppressed. A quiet channel may be cooling down; **Test** helps distinguish
that from a broken configuration.
## Admin: users and clients
Superusers use **Admin** to add, edit and remove accounts, and manage OAuth
clients for [agents](../code/agents.md).
Accounts admitted from a portal are marked *Portal*. They sign in through the
portal, have no local password and are not superusers. To block local access,
edit the account and clear **Is active?**. See [Accounts and the portal](portal.md).
## Settings
Change your name, email, password and appearance under **Settings**.
**Remote access** manages enrollment and admitted users; see
[Accounts and the portal](portal.md).
A superuser can configure **Assistant**: choose a provider, store its key,
fetch models and select one. The encrypted key is shared for assistant access
on this instance. The chat appears after configuration; see
[The assistant](../code/agents.md#the-assistant).
