# Monitoring Device Performance

To monitor the device-level performance information, double-click the device (that is, anywhere on the background of the image that is not a card or a port).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. The following is an example of the information displayed for many device types:

Memory Used %

Buffer Failures %

CPU Busy % (5 sec)

CPU Busy % (1 min)

CPU Busy % (5 min)

You can also display environment information for devices.

#### To monitor the device level information double click the device or,

Right-click the device. Select Configure from the dropdown menu.

# 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 %

Indicates the total number of allocation requests that have failed due to lack of free buffers.

# CPU Busy % - 5 sec (busyPer)

Provides the percentage of CPU usage over the first 5-second period with the scheduler. The scheduler determines which processor task takes priority over another and triggers them accordingly.

# CPU Busy % -1 min (avgBusy1)

Provides a cumulative average of the CPU usage percentage over a 1-minute period. This variable, polled by the scheduler every 5 seconds, computes the busy time in the last 5-second period, and the 5-minute exponentially delayed busy time.

# CPU Busy % - 5 min (avgBusy5)

Provides a cumulative average of the usage percentage over a 5-minute period. This variable, polled by the scheduler every 5 seconds, computes the busy time in the last 5-second period, and the 5-minute exponentially delayed busy time.
