Query Monitor is a per-request inspector. Most of its data, the SQL log, hook timeline, HTTP fan-out, and template includes, lives only for the lifetime of one page load and renders into the QM panel. There is no built-in database table that stores those records across requests, which is by design: the plugin is a debugger, not a logger.

Teams that want a longer view typically wire QM's logger API or its qm/collect/* action hooks into a custom table, capturing only the events worth keeping (slow queries over a threshold, PHP notices in admin, failed HTTP calls, cron drift). SleekView reads that captured table directly and presents the rows as columns you can sort by duration, filter by URL or component, and group by error type.

The grid does not turn QM into a real-time logger and does not replace the on-page panel for live debugging. It gives the data your team has already chosen to persist a working surface so a slow checkout query logged at 02:14 does not vanish after the next page refresh, and a recurring PHP notice can be counted, sorted, and triaged the same way support handles any other ticket queue.

Query Monitor is one of the best per-request debuggers WordPress has ever had, but its strength is also its scope. The data it shows lives for the lifetime of a single page load, then disappears. Teams that care about performance over weeks rather than seconds end up writing their own logger, capturing slow queries, PHP notices, and failed HTTP calls into a custom table so the data persists.

That captured table then sits in the database with no good way to look at it, and triage falls back to ad-hoc SQL or a plugin developer hand-rolling an admin screen. SleekView removes that final step. The captured log gets a sortable, filterable grid with saved views for the questions teams actually ask: which page produced the slowest queries this week, which component generated the most PHP notices, which external API timed out yesterday morning.

The captured data is whatever your logger writes, kept tight and honest, and the grid is the missing operator surface on top of it. Nothing about QM's live panel changes; it simply stops being the only place the data ever lives.
