Configuring Persistent Logging Options

If the system unexpectedly reboots, log messages can be useful to diagnose the cause.
However, log messages are erased when the system reboots unless you enable persistent
logging.
Enabling persistent logging can wear out the non-volatile (flash) memory
CAUTION:
and degrade network performance. You should only enable persistent
logging to debug a problem. Make sure you disable persistent logging
after you finish debugging the problem.
To configure persistent logging on the Events page, set the persistence, severity, and depth
options as described in

Table 25. Logging Options

Field
Persistence
Severity
Depth
NOTE: To apply your changes, click Update. Changing some access point settings
might cause the AP to stop and restart system processes. If this happens,
wireless clients will temporarily lose connectivity. We recommend that you
change access point settings when WLAN traffic is low.
Table 26, and then click Update.
Description
Choose Enabled to save system logs to non-volatile memory so that the logs are
not erased when the AP reboots. Choose Disabled to save system logs to volatile
memory. Logs in volatile memory are deleted when the system reboots.
Specify the severity level of the log messages to write to non-volatile memory.
For example, if you specify 2, critical, alert, and emergency logs are written to
non-volatile memory. Error messages with a severity level of 3-7 are written to
volatile memory.
• 0—emergency
• 1—alert
• 2—critical
• 3—error
• 4—warning
• 5—notice
• 6—info
• 7—debug
You can store up to 128 messages in non-volatile memory. Once the number you
configure in this field is reached, the oldest log event is overwritten by the new
log event.
