You may need WordPad or similar software to see the log report correctly.
The table below describes
the fields in the above screen.
Table 150
Management > Maintenance > Tech-Support
CPU
Type a number ranging from 50 to 100 in the CPU threshold box, and type
another number ranging from 5 to 60 in the seconds box then click Apply.
For example, 80 for CPU threshold and 5 for seconds means a log will be created
when CPU utilization reaches over 80% and lasts for 5 seconds.
The log report holds 7 days of CPU log data and is stored in volatile memory
(RAM). The data is lost if the Switch is turned off or in event of power outage.
After 7 days, the logs wrap around and new ones and replace the earliest ones.
The higher the CPU threshold number, the fewer logs will be created, and the
less data technical support will have to analyze and vice versa.
Mbuf
Type a number ranging from 50 to 100 in the Mbuf (Memory Buffer) threshold
box. The Mbuf log report is stored in flash (permanent) memory.
For example, Mbuf 50 means a log will be created when the Mbuf utilization is
over 50%.
The higher the Mbuf threshold number, the fewer logs will be created, and the
less data technical support will have to analyze and vice versa.
Apply
Click Apply to save your changes to the Switch’s run-time memory. The Switch
loses these changes if it is turned off or loses power, so use the Save link on the
top navigation panel to save your changes to the non-volatile memory when you
are done configuring.
Cancel
Click Cancel to begin configuring this screen afresh.
All
Click Download to see all the log report and system status. This log report is
stored in flash memory. If the All log report is too large, you can download the
log reports separately below.
Crash
Click Download to see the crash log report. The log will include information of
the last crash and is stored in flash memory.
CPU history
Click Download to see the CPU history log report. The 7-days log is stored in
RAM and you will need to save it, otherwise it will be lost when the Switch is
shutdown or when there is a power outage.
Memory Section
Click Download to see the memory section log report. This log report is stored
in flash memory.
