A log records messages equal to or above a configured severity threshold. For example,
if you select Error, the logged messages include Error, Critical, Alert, and Emergency.
The default severity level is Alert (1). The severity can be one of the following levels:
• Emergency (0). The highest warning level. If the device is down or not functioning
properly, an emergency log is saved to the device.
• Alert (1). The second-highest warning level. An alert log is saved if there is a serious
device malfunction, such as all device features being down. Action must be taken
immediately.
• Critical (2). The third-highest warning level. A critical log is saved if a critical device
malfunction occurs, for example, two device ports are not functioning, while the rest of
the device ports remain functional.
• Error (3). A device error has occurred, such as if a port is offline.
• Warning (4). The lowest level of a device warning.
