bvandeusenandClaude Opus 5.5	b8f73270e7	perf(metrics): a latest-value table for "what is it now"; dashboard cells say loading, failed and as-of (#5208) ... The dashboard's host widgets took 18-60 s. Every "latest reading" query (hosts overview, host-agent fleet, host page, vitals, SNMP, MCP get_host) searched plugin_metrics for the newest row per metric. Postgres has no skip scan, so each one read every raw sample in the 7-day window. - plugin_metric_latest: one row per (source, resource, metric). record_metrics upserts it in the same transaction, moving forward only and in sorted key order. Migration 0030 seeds it by stepping the existing index. - Retention drops a latest row once its sample leaves the raw window, so a resource that stopped reporting disappears when its history does, as before. Renames carry it along. - A quiet host keeps its last values, marked stale. A time-bounded query would have shown it as missing. - Vitals sparklines span the 6 h they claim, averaged in SQL to ~120 points, instead of fetching 6 h raw and drawing the last 120 samples. - Dashboard and share-view cells: "Loading…" until the first answer; a 20 s deadline per fetch; "Couldn't load (why)" with Retry now and an automatic retry for cells that don't poll; "as of HH:MM" in the header, and "couldn't refresh · as of" when a refresh fails over shown data.

bvandeusenandClaude Opus 5.5	c9f5c049db	feat(alerts): renames carry their alerts — monitor and host renames move rules, windows and history (#5065) ... #5065 "Renames carry their alerts". Alert rules, maintenance-window scopes and metric history key a thing by (source, name), so a rename used to leave the rules watching a name nothing reported under, and split the history. - core/renames.carry_rename moves AlertRule.resource_name, MaintenanceWindow.scope_resource, plugin_metrics and plugin_metrics_hourly to the new name in the caller's transaction. A host rename also carries its parts: host_agent "<host>:…" and docker "<host>/…" (HOST_SOURCES). Matching is exact (a prefix compare, not LIKE or a collation range). History left under the new name by something deleted is dropped first rather than merged in. - Web monitor edit, MCP update_monitor and web host edit call it; MCP answers with `carried` (it used to return a warning naming stranded rules). - A name another monitor of the same type, or another host, already has is refused on create and rename: two would share one history. - The rename is audited (monitor.updated / host.renamed) with what moved. Tests: an integration test renames a firing monitor through the web route and finds its rule still firing and cleared by a sample on the new name, its window and raw+hourly history moved and an orphan's history dropped; a host rename moves agent and container parts but not a longer-named host's or another source's; a guard that every host_agent resource is "<host>" or "<host>:…".
