[ MONITORS & ALERTS ]

Uptime monitors and alerts

CanaryHub checks your URLs on a schedule and notifies you the moment something goes wrong — and again the moment it recovers. No manual refreshing, no wondering.

Uptime monitors

Open Dashboard → Monitors and hit Add monitor. Fill in a name, your URL, and optionally a health path (more on that below). That's it — CanaryHub starts polling immediately.

• Check interval: every 5 minutes on the free plan, every 60 seconds on Pro.
• Plan limits: Free covers 1 project with up to 3 monitors — enough to watch one app properly (site, API, and one more). Pro covers 3 projects with unlimited monitors each; Business (coming soon) is unlimited.
• No flapping alerts: a monitor goes down only after 2 consecutive failed checks. Recovery is confirmed on the first successful check. A single blip won't wake you up.
• Pause / resume / delete from the same Monitors page when you need to take a service offline intentionally.

Health endpoint (optional, but better)

A plain URL check can only tell you HTTP up or down. If you point the monitor at a /api/health path that returns the standard contract below, CanaryHub can also see degraded states and which sub-check (database, external API, queue, …) actually failed.

{  "status": "ok",  "version": "a3f9c12",  "checks": [    { "name": "database", "status": "ok", "latencyMs": 12 },    { "name": "redis",    "status": "ok", "latencyMs":  3 }  ]}

status must be one of ok, degraded, or down. Individual check statuses follow the same three values. The endpoint should be fast and side-effect free — it runs every poll cycle.

Telegram alerts

Telegram is the fastest way to get notified. Connect it once:

1. Open Dashboard → Notifications and find the Telegram card.
2. Tap Connect Telegram — a link opens the CanaryHub bot in Telegram.
3. Press Start in Telegram. Done.

From then on you get a 🔴 message the moment a monitor goes down, and a 🟢 message when it recovers. On the free plan, alerts are batched — at most one update per monitor every 4 hours, so if a service flaps you get a concise summary rather than a flood.

You can also message the bot /status any time for a quick account summary — events and errors from the last 24 hours — without opening the dashboard. Disconnect from the same Settings card whenever you like.

Slack alerts

CanaryHub posts alerts into any Slack channel through an incoming webhook — no app install or admin approval needed. One-time setup, about two minutes:

1. Open api.slack.com/apps and hit Create an App → From scratch. Name it anything (e.g. “CanaryHub Alerts”) and pick your workspace. Don't worry about the Client ID / secrets screen it lands on — you won't need any of it.
2. In the left sidebar, open Incoming Webhooks and flip the toggle On.
3. Scroll down, click Add New Webhook, and pick the channel (or DM) alerts should land in.
4. Copy the generated URL (starts with https://hooks.slack.com/services/…) and paste it into Dashboard → Notifications → Slack alerts, then hit Connect Slack.
5. Press Send test alert — a ✅ message should appear in your channel within a second or two.

The Incoming Webhooks page after step 2 — toggle on, then “Add New Webhook” at the bottom.

Discord alerts

Discord webhooks live right inside your server's channel settings — no developer portal at all:

1. In your Discord server, hover the channel you want alerts in and click the gear icon (Edit Channel).
2. Open the Integrations tab → Webhooks → New Webhook.
3. Click your new webhook and hit Copy Webhook URL (starts with https://discord.com/api/webhooks/…).
4. Paste it into Dashboard → Notifications → Discord alerts, hit Connect Discord, then Send test alert to confirm.

Channel settings → Integrations — webhooks are two clicks from any channel you manage.

For both channels: the webhook URL is a secret — anyone who has it can post to your channel, so treat it like a password. Disconnect any time from the same Notifications card; alerts follow your urgency, quiet-hours, and detail-level preferences just like Telegram.

SMS alerts

SMS alerting is live for US numbers. Down/recover texts arrive from CanaryHub's dedicated number, and the same number answers commands.

• Register your number. Add it in Settings → SMS and confirm consent — alert texts start with the next incident.
• Text commands. Text the number any time and get replies: /status (account summary), /whoami (confirm which account your number is linked to), /mute / /unmute (silence and restore alerts), /help (command list). Standard STOP / START also work and mirror into your alert settings.

SMS alerts are always sent in the compact format regardless of your detail-level setting, and message frequency depends on your monitors — reply STOP any time to opt out.
