Question : Problem: How to Interpret CPU Utilization Graph
|
|
Can someone explain to me how to interpret the output for "show proc cpu hist" on a cisco router or switch.
There are t00 many numbers I don't know which is which. I understand the numbers on the left side of the graph that they represent the % utilization. What I don't understand is what number represents what for the two rows at the bottom. I know they say the represent the time, but which one of the bottom rows ( X axis). How do you read the stream of numbers at the to, I also know they represent % utilization, but how do you know which row to use, top or bottom?
Refer to the pasted output if there is need.
#sh proc cpu history

Question 2:
Is it possible to hard code the speed and duplex settings for fiber gig port . I am able to do so on a copper gig port but not fiber with SFP or GBIC?
Thanks

Don't look at the bottom numbers as two separate rows of numbers...look at them like they are a single number oriented vertically...they should be read like this:
From the "last 60 minutes" graph above:
0....5....1....1....2....2....3....3....4....4....5....5....
0 5 0 5 0 5 0 5 0 5
| | | | | | | | | | | |
0 5 10 15 20 25 30 35 40 45 50 55
See the correlation?
