How UpDog + Slack works

UpDog posts to Slack when a monitor changes state so your team can triage incidents where work already happens. Keep messages consistent, route to the right channel, and include one clear link back to investigation context.

What the alert includes

  • Monitor name + environment
  • Down/recovery state change and timestamp
  • One link back to UpDog for timeline + check details

How teams reduce noise

  • Dedicated #ops or #status channel for production
  • Separate channels for staging/dev
  • Route by service ownership (API, frontend, infra)

What you can do with UpDog + Slack

  • Send Slack uptime alerts for downtime and recovery so responders see state changes instantly.
  • Route by ownership: put API alerts in one channel and frontend alerts in another.
  • Keep messages actionable with a clear monitor name, timestamps, and a link back to UpDog.

How to set it up (step-by-step)

  1. Create (or pick) an uptime monitor in UpDog.
  2. Create an alert for that monitor.
  3. In the alert modal, choose Slack as the destination.
  4. Follow the prompts to connect Slack and select the channel (workspace auth vs webhook URL depends on your Slack setup).
  5. Save the alert, then send a test notification to confirm routing.

Best practices

Reduce noise (and keep Slack usable)

Slack is great for collaboration. It’s not great when every minor blip floods the channel. Route only high-signal monitors to Slack and keep low urgency updates in email.

Use one channel per environment

Split production alerts from staging/dev. Your future self will thank you at 2am.

Pair Slack with escalation when needed

If an incident requires guaranteed response, route it to an on-call tool (e.g., PagerDuty) and post to Slack for visibility.

Troubleshooting

  • No Slack uptime alerts are arriving: verify the Slack connection, destination channel, and that the monitor is assigned to the integration.
  • Alerts are going to the wrong channel: confirm per-monitor routing rules (especially if you have multiple workspaces/channels).
  • Too many alerts: lower the number of monitors routed to Slack, tune check intervals/retries, or move noisy checks to email.
  • Webhook URL fails: if you’re using a webhook URL, check that it hasn’t been rotated or restricted by workspace settings.

FAQ

Create an alert in UpDog, choose Slack as the destination inside the alert modal, connect Slack, pick a channel, and send a test notification.

Yes—route by service ownership (API, frontend, infra) and keep production separate from staging/dev.

Monitor name, state change (down/recovered), timestamp, and one link back to UpDog for the incident timeline and last check details.

Double-check the Slack connection, that the monitor’s alert is routed to Slack, and that your channel selection matches the intended destination.

Send only high-signal monitors to Slack. Consider routing low urgency notifications to email and reserving Slack for production-critical events.

Use Slack for collaboration and visibility. Use PagerDuty for incidents that need escalation and guaranteed response. Many teams use both.
