Event Severities
The system provides the flexibility to configure the level of information that is displayed when logging is
enabled. The following levels are supported:
•
critical: Logs only those events indicating a serious error has occurred that is causing the system tor a
system component to cease functioning. This is the highest severity level.
•
error: Logs events that indicate an error has occurred that is causing the system or a system component
to operate in a degraded state. This level also logs events with a higher severity level.
•
warning: Logs events that may indicate a potential problem. This level also logs events with a higher
severity level.
•
unusual: Logs events that are very unusual and may need to be investigated. This level also logs events
with a higher severity level.
•
info: Logs informational events and events with a higher severity level.
•
trace: Logs events useful for tracing and events with a higher severity level.
•
debug: Logs all events regardless of the severity.
Each of the above levels correspond to the "severity" level of the event ID. Therefore, only those event IDs
with a "severity" level equal to the logging level are displayed.
