CSS Flow Statistics Description

[ppatel]

When a flow statistics is performed in debug mode on a CSS what do the following fields actually mean

FM TCP Flows Timed Out 51

FM UDP Flows Timed Out 0

FP TCP Flows Timed Out 4304192

FP UDP Flows Timed Out 869078

It tells you how many times the CSS removed the flow because it had seen no

activity on it.

Any flow that remains inactive for the default/configured timeout value ( I think its 16sec for http)is timed out.

You can increase this timer by

using the "flow-timeout-multiplier " under the content rule. This parameter

is detailed here:

content yourcontent

add service yourservice1

add service yourservice2

vip address x.x.x.x

advanced-balance sticky-srcip

sticky-inact-timeout 600

flow-timeout-multiplier 5400

active

(The value to choose with flow-timeout-multiplier command should be in increments of 16 seconds.For eg the above value means one day (5400x16=86400secs).

Hi Syed Iftekhar,

What does the FM TCP Flows Timed Out 51 exactly mean. Does it mean a flow is setup in the slow path and it is not pushed to the fast-path cache but still abides by the flow-timeout parameter?
