Sailfish docs
Sailfish reads MySQL's performance_schema every five minutes, keeps what moved past the restarts that
reset it, and serves a dashboard for it at
/sailfish. These pages cover getting
it in, what it records and for how long, and the events it sends when something on the server changes.
Getting started
Configuration
Using Sailfish
The dashboard
What each page of /sailfish shows, and the two gates that decide who sees it.
What gets recorded
The sailfish_* tables, where each counter comes from, and how deltas survive the ways performance_schema resets.
Retention and rollups
Seven days of five-minute snapshots, ninety of hourly ones, then daily ones for good.
Statement digests
MySQL 8.0 gives no digest to native prepared statements, which is what Laravel sends by default.
