Get alerted when your website traffic drops or spikes
The worst analytics problems are the quiet ones. A deploy removes the tracking script, a campaign ends, a page starts erroring, and nothing tells you. You find out two weeks later when you look at a chart and wonder where the traffic went.
A website traffic drop alert closes that gap. You set a rule once, and Mitr watches your numbers every day and tells you only when they stop looking normal.
How the check works
Every day Mitr takes yesterday’s total event count across every app connected to your workspace and compares it with the average of the seven full days before yesterday. If the difference crosses your threshold in the direction you chose, a notification goes out.
- Direction: alert on a drop, on a spike, or on both.
- Metric: total daily events, workspace-wide.
- Check frequency: once a day, early morning UTC.
- Throttling: at most one notification in any rolling 24 hours, so a long outage sends one message, not thirty.
Comparing with a 7-day average, instead of with the previous day, matters. Traffic has a weekly rhythm, so “down on Sunday” is normal for many sites and is not an anomaly. A week of context smooths that out.
Set one up in a minute
- Open Settings → Alerts in the dashboard.
- Choose the direction: drop, spike or both.
- Set a threshold, the size of the change that should trigger it.
- Pick where it goes: email, a webhook, or Slack.
- Save.
Choosing a threshold
The threshold is a percentage change. You can set it anywhere up to 500 percent, and a new rule starts at 50 percent, in both directions. There’s no universal right answer, so treat these as starting points:
- Start around 40 to 50 percent for a drop. A smaller threshold tends to fire on ordinary weekend dips until you start ignoring it, which defeats the point.
- Tighten it once you know how steady your traffic is. Watch a few weeks of normal behaviour, then lower it if you want earlier warning.
- Turn on spikes if you run campaigns or get press. It tells you a post took off while it’s still worth reacting to.
- Go looser if your traffic is very small. A few events can swing the percentage a lot.
A drop to nearly zero is almost always your tracking breaking and not your audience vanishing. Either way you want to know the same day.
Where the alert goes
| Channel | What you get |
|---|---|
| A message to your account address | |
| Webhook | A signed request to any URL you control, delivered the same way as event webhooks |
| Slack | A message in a channel, via a Slack incoming webhook URL |
You pick one channel per rule. If you want it in several places, point the webhook at an automation tool and fan it out from there.
What it doesn’t do yet
Being straight about the limits: there is one rule per workspace, it watches one metric (total daily events), and it’s evaluated once a day, so it is not real-time. There’s no per-site or per-event alerting and no error-rate metric today. The full reference is in the alerts docs.
Alerts and reports work together
An alert is the safety net. The weekly analytics email report is the regular check-in. Together they mean you hear about a problem the next morning and see the bigger picture every Monday.
Start free, connect a site, and set your first alert while you’re there.
Frequently asked questions
How does Mitr decide that traffic has dropped?
Once a day Mitr compares yesterday's total event volume across all connected apps with the average of the seven full days before it. If the change crosses the threshold you set, in the direction you chose, you are notified.
Where can the alert be sent?
One channel per rule: email to your account address, a webhook to any URL you control, or a Slack channel through an incoming webhook URL.
Will I get an alert every day during a long outage?
No. A rule sends at most one notification in any rolling 24 hours, so a multi-day problem does not flood you.
Can I set alerts per site or per event?
Not yet. There is one rule per workspace and it watches total daily event volume. If you need per-site or per-event alerts, tell us at support@mitranalytics.dev.
