A flat line raises no alarm.

A real caseMarch 2 to 11

Nine days without a single signup, and not one alert

Here is what happened, hour by hour, and what each module saw. It is also what the pen draws in the margin: it goes flat at the exact moment signups stop.

1. March 2, 22:40

   A DNS record is changed

   The domain’s SPF record changes. Nobody on the team asked for it — the host rewrote the zone. The Watch module sees it on its daily pass.

2. March 3, 00:05

   The emails still go out

   The Mail module keeps sending signup confirmations. Every message is accepted by the recipient’s server, which answers 250 OK. The dashboard shows 100% delivered. But the messages land in spam, and nobody opens them.

3. March 3, 04:12

   Signups stop

   The Stats module counts 4 signups that day, against 44 on the same weekdays of previous weeks. It does not compare to yesterday — it compares to the same weekday, so a Sunday is never mistaken for an outage.

4. March 3, 04:13

   The connection, and the alert

   The Signals module sees two findings on the same domain less than three days apart: a DNS change and a business collapse. It emails the team, with a single sentence.

“Your signups dropped 91% on March 3.
Your SPF record changed on March 2.”

An analytics tool does not look at your DNS. A monitoring tool does not count your signups. Neither one can write that sentence. You need both, in the same account, on the same project.

Today’s report5 checks

All green. One check is lying.

Here is what a classic dashboard shows. Five green lines, five checks answering. One of these five is broken — and nothing in this list lets you tell which.

The catalogue11 modules

What each module does, in one sentence

They all come with the same account, and they share the same projects and the same domains.

• Signalsconnections

  Connects what two modules found on the same domain a few days apart, and writes it out in one sentence.

• Cronscheduled jobs

  Watches your scheduled jobs. It tells you when one did not start on time, and when it answered OK without writing anything.

• Statsaudience and events

  Counts your visits and your business events — orders, signups, payments. It warns you when a number collapses against the same weekdays of previous weeks. No cookie, no banner.

• Mailtransactional email

  Sends your email and tells you what became of it: delivered, opened, clicked, bounced, filed as spam. It delivers directly, with no middleman, signed with your own DKIM key.

• SEO & LLMsearch and AI

  Verifies that Google, Bing, ChatGPT, Claude and Perplexity can actually read your pages, and counts which ones came.

• Errorsexceptions

  Receives your site’s JavaScript and server errors, groups them by cause, and tells you how many visitors each one actually hit.

• Uptimeavailability

  Calls your pages every minute from the outside. It checks the HTTP code, but also that the expected content is really in the page — an empty page answers 200.

• Watchdomain, DNS, certificate

  Checks your certificate, your domain name and your DNS records every day — SPF, DKIM, DMARC, MX, CAA. It tells you the day one of them changes, even when you changed it yourself.

• Forumcommunity

  A help forum on your own domain, so your users can answer each other.

• AIagents

  Records what your AI agents do: cost, duration, answer. It warns you when an agent reports OK without having done anything.

• Authsign-in

  Gives your apps a sign-in screen you do not have to build. Passwordless, standard OpenID Connect, accounts separated by project.
