Database statistics in Settings > Data
New GET /api/dbstats reads VictoriaLogs /metrics (stored lines, size on disk, raw size, free space, partitions, retention) and two LogsQL queries (period covered, distinct hosts and apps, lines of the last 24 h and hour), cached for 30 s. The danger zone shows them, sizes in KB/MB/GB or Ko/Mo/Go. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
