Monitoring Library Events
Generating Reports and Logs 12-5
Request Identifier
Identifies all host interface requests. Helps track the sequence of log activity resulting
from each host request.
Severity
Identifies the significance of the event. Some event data is non-volatile, meaning it
persists across system power cycles.
Error — non-volatile data indicating a fault that prevented a request (host or
diagnostic) from completing successfully.
Warning — non-volatile data indicating a fault that has not stopped the library's ability
to complete requests (host or diagnostic). A warning can identify a loss of performance
or a condition that may indicate future irrecoverable errors.
Information — volatile data indicating general device or library information (such as
the device state, device added, listener registered, tray serial number updated, and so
on). This information may be important to establish a history of activity for the
warning or error event.
Trace — volatile data indicating diagnostic activity tracing.
Result Code
Identifies the library event type (result codes are the same as library EventIds). To
search for the meaning of the Result Code using SLC, see
"Displaying Result Code
Definitions" on page 12-4 or refer to the SL8500_FRS xxx _JavaErrorCodes.html file
included in the library firmware code package.
Result Text
Provides information about the results of the request or event.
