WP Rocket's strength is its invisibility: toggle the right options and the cache fills, the preload runs, and the front end serves static files. The trouble starts when something quietly stops working. Used CSS fails on a handful of templates, preload stalls on specific URLs, and the global progress bars still look healthy. The data needed to spot trouble already exists in the wp_wpr_rocket_cache, wp_wpr_rocket_preload, and wpr_used_css tables. Only the rendering is missing.

SleekView Charts reads those tables as a normal data source and renders chart cards over the cache state. A Number card carries the total URLs cached, a Donut splits the preload queue by status, a Bar lists the post types producing the most Used CSS failures, and an Area chart traces daily refresh activity so post-deploy regressions show up as flat lines instead of stakeholder tickets.

The cache itself stays in WP Rocket's hands. Charts query the same indexes the plugin's admin uses, and saved dashboards can be scoped per role so an agency support lead reads the operational view while a developer reads the failure queue. Nothing is rewritten on the cache tables and no separate aggregation layer is introduced.

WP Rocket succeeds by being mostly invisible, which is also why its data stays mostly invisible. The cache fills, the preload runs, and the global percentage looks healthy until a stakeholder reports a slow page. The data needed to spot trouble already exists in three small tables that WP Rocket maintains with the right indexes.

Visualising those tables as Number, Pie, Bar, and Area cards costs nothing on the writing side and reframes the same rows as a dashboard. The cadence of performance review shifts from a quarterly scramble to a daily glance, and the cache stays exactly where WP Rocket left it.
