The index collector now sums index reads and writes between collections
across restarts of SQL Server (and of the agent, by seeding from the
stored snapshot) and keeps them per day in insight.IndexUsageDaily
(migration 0015, HourlyDays). SQLI-IDX-002 judges an index once it has
been followed for 7 days instead of needing 7 days of uptime.
GET /api/v1/instances/{name}/index-usage lists usage per index.
SQLI-STAT-001 also reports statistics that were never updated on tables
with rows; statistic rows now come from the table's heap or clustered
index, as a never-updated statistic has no row count of its own.
