## Request, System and Cluster Metrics

At a high level metrics are grouped into three categories, listed in the following sub-sections. The path in each of the tables is relative to the top-level endpoint.

	ExcessFolders    = "alert_excess_folders"
	EnvExcessFolders = "MINIO_SCANNER_ALERT_EXCESS_FOLDERS"

	// All below are deprecated in October 2022 and
	// replaced them with a single speed parameter
	Delay            = "delay"
	MaxWait          = "max_wait"
	Cycle            = "cycle"
	EnvDelay         = "MINIO_SCANNER_DELAY"
	EnvCycle         = "MINIO_SCANNER_CYCLE"

for existing object replication are detected when scanner runs, and will be replicated if existing object replication is enabled and applicable replication rules are satisfied. Because replication depends on the immutability of versions, only pre-existing objects created while versioning was enabled can be replicated. Even if replication rules are disabled and re-enabled later, the objects created during the interim will be synced as the scanner queues them. For saving iops, objects qualifying for...
