Understanding STA Analytics : STA Data Store

STA Data Store

Following is a summary of the types of data included in the data store.

•
Library configuration model – A hierarchical view of the library and device configurations, properties, and statuses. To retrieve this information, STA initiates data collections through a series of SNMP requests sent to the library.
•
Exchange records – Detailed information about all drive and media exchanges, including cleaning activities. The library sends this data to STA through asynchronous SNMP traps.
•
Errors and events – Records of significant library errors and events. The library sends this data to STA through asynchronous SNMP traps.

See Chapter 2, “Managing Library SNMP Connections” for details on how STA receives this data from the libraries.

Data Retention

Data in the STA data store is retained indefinitely as a historical record and never deleted. However, data for removed resources — libraries, drives, and media — may be hidden from the STA data screens, depending on the Data Handling settings for your username. See “Removed Drives and Media” and “Removed Libraries” for details.

When STA first begins tracking a library, drive, or media, that resource is assigned an STA Start Tracking timestamp. If the resource is later removed from the library environment, an STA Stop Tracking timestamp is assigned. And then if the resource is later re-added, the STA Start Tracking attribute reflects the original timestamp assigned when STA first began tracking the resource.
