Attribute values

Attributes are reported by services on a best-effort basis. Attribute updates can be lost under some circumstances, such as the crash of a service or the failure and rebuild of a grid node. For example, if an LDR service crashes after it has registered the ingest of a number of objects, but before it has committed the updated attribute value to disk, any attribute updates since the last commit are lost.

Propagation delays might slow the reporting of attributes within the StorageGRID Webscale system. Updated values for most attributes, except for state attributes, are sent to the StorageGRID Webscale system at fixed intervals. For this reason, it can take a few moments before an update is visible in the system, and two attributes that change more or less simultaneously can be reported at slightly different times.

Attribute values should be understood as being approximately correct, particularly for "count" attributes such as object count or HTTP connection attempts.
