To monitor device-level performance information, right-click the device (that is, click some part of the background of the image that is not a card or a port) and select Monitor from the popup menu. The CiscoView Monitor Device window appears. It graphically displays memory usage and buffer status information for each device. The information fields may vary according to the device type.
Right-click the device and then select Monitor.
Select Device from the Category list.
The following information is displayed for many device types:
Memory Used %
Displays the percentage of memory consumed.
For IOS Versions prior to 11.1, this percentage is calculated as follows:
100 - ( ( freeMem / processorRam ) * 100 )
For IOS Version 11.1 and later, this percentage is calculated as follows:
ciscoMemoryPoolUsed / ( ciscoMemoryPoolUsed + ciscoMemoryPoolFree ) * 100
Buffer Failures %
The percentage of allocation requests failed.
The formula is :
[ ( bufferFail ) / (bufferHgHit + bufferLgHit + bufferBgHit + bufferMdHit + bufferSmHit + bufferFail) ] * 100
The percentage of CPU usage over the first 5-second period with the scheduler. The scheduler determines which processor task takes priority over another processor task, and then triggers the tasks accordingly.
A cumulative average of the CPU usage percentage over a 1-minute period. This variable, called by the scheduler every 5 seconds, computes the busy time in the last 5-second period, and the 1-minute exponentially delayed busy time.
