SHARE
SHARE = 0.25
Share of the discovered keyspace that may be undecided before this fires.
Too much of the ephemeral keyspace is being captured without anyone knowing what it is.
Unclassified keys are captured on purpose: an unrecognised key is a gap in the heuristics rather than evidence it does not matter, and dropping it would create a silent hole. But that default is safe only while the unclassified share stays small. A newly installed module that names its cache bin unconventionally can put millions of derivable keys into the backup, and the first sign would otherwise be the storage bill.
A warning, not an error: nothing stored is wrong, and the fix is a person spending a minute on the classification page.
check(array $observation) : \Drupal\strata\Health\Finding|null
Evaluates the check against one observation.
| array | $observation | Scalars the caller already had in hand. A tripwire reads from this and nothing else. |
A finding when the symptom is present, or NULL when the check is satisfied.
