Why we alert on failed checkouts and slow logins instead of CPU, and how to write your first rule.

The short version

Most teams collect far more data than they read. The trick is deciding in advance which signals always matter, then letting everything else be sampled, summarised or dropped.

How to try it

Open any project, go to Settings, and turn on the default rules. You can see exactly what was kept and why in the Sampling panel.

What to watch for

If a rule drops something you needed, add an exception from the log line itself. It takes effect within a minute.
