Only WordPress data: wp_redirection_items (url, action_code, match_type, regex, last_count, last_access, status, group_id), wp_redirection_groups, wp_redirection_logs (the matched-hit log) and wp_redirection_404 (paths that did not match any rule). SleekView never re-runs the matcher or re-crawls the site.

No. Redirection still owns the matching engine, regex parser, group ordering and the actual HTTP response. SleekView only reads from the tables Redirection writes. Disabling or deleting SleekView leaves every redirect rule firing exactly as it did before.

Yes. Group a Pie or Bar by action_code and the chart shows the 301 vs 302 vs 307 vs 308 vs 410 mix. Useful for spotting legacy 302s that should have been 301s years ago, and for confirming that gone pages are returning 410 rather than a stale 301 to the homepage.

Yes. Group a Bar card by url and aggregate Sum on last_count, and the chart ranks rules by the hit count Redirection itself stores. The rules that carry the actual traffic become visible, which is what a cleanup decision needs.

Yes. wp_redirection_404 carries a created timestamp per logged 404, so an Area card grouped by created with a Count aggregation gives 404s per day. Migration sign-offs use the trend to confirm that new rules are catching the legacy URLs.

Yes. Redirection groups (modified, wp_redirection_groups) carry their own ids; a filter on group_id narrows every card. A site with separate redirect groups for blog, shop and docs can dashboard each one independently.

Yes. Any filtered set behind a card exports as CSV with the same columns the audit table would show. Useful for archiving a redirect snapshot before a major cleanup, or for handing a 404 list to a migration contractor.

Partially. The wp_redirection_items table is always populated, so the rule, status, group and last_count cards work. wp_redirection_logs and wp_redirection_404 only fill when their respective logging options are enabled in Redirection's settings, and SleekView mirrors that honestly: if logging is off, the log and 404 cards show empty rather than fabricated numbers.
