Aggregating and Holding Cluster Data

Unwired Platform uses the cluster database to centralize the collection of all cluster data that becomes the payload to SLD servers.

Information is collected from each Unwired Server node that is a member of the identified cluster, and each node follows the schedule configured and enabled for the cluster. A single database transaction creates the database entry.

Once data is in the database, it is held until the next schedule milestone is reached, whereby a payload is generated and sent to the SLD destination server. At this point the data is purged from the database. When the next collection is requested by the schedule, a new set of cluster data is aggregated, held, delivered, and purged.

Note: During this process, if some nodes fail or are otherwise disabled (thereby preventing the collection task from being performed), the aggregated data currently held in the database generates the payload for those nodes.
