LABEL DESCRIPTION
CPU Loading 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 Usage 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.
