Keep every error and every slow request, drop the noise. Here is the rule set we ship by default.
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.
