Hi Experts,
Can any body clearly explain about cpu utilization that how we will caliculate and what are points we should look when calculating cpu utlization.
Below I am pasting one router cpu utilization.
Router1#sh processes cpu history

Hi Naidu,
I'm explaining the first graph details..which is last 60 sec history...
Y-axis is for CPU utlization..
X-axis is the time in seconds...which is you can read the columns as 0sec,5 sec, 10sec,15 sec...pls note the values are in vertical for 10 sec its 1 and below is 0...for 35th sec..its 3 and below is 5..
Please check the values again the switch/router..as the alignment of values posted here is gone.
The top two columns denote the maximum cpu utlized...in seconds graph..its 31%...read vertically..
in 60 minutes its 30%, in 72 hrs..its 34%..
I hope u understood it...you can go thru the following link for detailed explanation.

Please rate if it helps..
