FWSM 3.1(8) - Security context high CPU usage

limtohsoon — Mon, 11 Mar 2019 11:49:54 GMT

Hi Sir,

Below is output of "sh cpu usage context all" on a FWSM version 3.1(8):

FWSM# sh cpu usage context all

5 sec 1 min 5 min Context Name

10.0% 9.0% 8.9% system

0.0% 0.0% 0.0% admin

47.5% 46.4% 45.8% fwsm-context1

0.0% 0.0% 0.0% fwsm-context2

0.1% 0.0% 0.0% fwsm-context3

1.3% 1.2% 1.2% fwsm-context4

0.4% 0.4% 0.4% fwsm-context5

0.2% 0.1% 0.1% fwsm-context6

0.3% 0.2% 0.2% fwsm-context7

0.1% 0.1% 0.1% fwsm-context8

0.0% 0.0% 0.0% fwsm-context9

0.2% 0.0% 0.0% fwsm-context10

Any way to see the breakdown of the CPU processes that contribute to the high utilization of fwsm-context1?

Users have been complaining slow access to servers connected to fwsm-context1 after the FWSM was upgraded from 2.3(3) to 3.1(8). Unfortunately I don't have the benchmark of the CPU usage on version 2.3.

Thank you.

B.Rgds,

Lim TS

In FWSM 3.x, "show cpu context all" shows where ALL the CPU cycles are

spent and each column should add to 100%. As a result, the numbers for

"system" and "" represent both idle and "work" cycles. If you

do that command in a totally idle system, you'll see that the columns

add to 100% and all the CPU cycles are spent in system and kernel, even

though there's no "real work" being done and "show cpu" shows 0% across

the board.
