storage_capacity_rca
Identifies and ranks storage-domain capacity problems worst first, flagging critical free-space shortfalls, low-space warnings, and inactive domains using engine thresholds and correlated events.
Instructions
[READ] Storage-domain problems ranked worst first, in one call.
Critical when free space is below the engine's critical blocker (the engine then
refuses new disks and snapshots); medium below the low-space warning, or when thin
disks are committed beyond capacity while space is low (low on its own); high when
an attached domain is inactive, unknown or mixed. Warning-or-worse events naming a
storage domain (for example "deactivated by system") are attached to it.
Unattached domains such as the default image repository are skipped. A domain whose
thresholds are unset (the engine reports 0) is reported low with its measured free
space: nothing — not the engine, not this tool — will warn before it fills, and how
full is too full is not recorded anywhere to read. Over-commit
on its own is a planning limit, and its signal carries actual use next to it: do
not report an over-committed domain as short of space unless a low-space or
blocker finding says so. Report findings in rank order and quote their signal.
Args: events_limit: Recent warning-or-worse events to correlate, 1-1000 (default 200). events_window_hours: Ignore events older than this many hours, 1-720 (default 24). target: Engine target name from config; omit to use the default.
