NimbostratusIn/Out Traffic Statistic on F5-LTM in HA mode
Hi,
I've got a HA pair, one acting as Active and one as Standby. I have set up a Virtual Server [VS-IP] for SSH sessions using port 22, so the F5 Load balances the requests to the VS-IP throughout the Servers behind.
When I have a look to the Traffic Statistic generated, under Statistic>>Module Statistic>>Local traffic>>Pools , What I see is:
- On the Active one I can see something like:
and for the Standby is:
the Question that springs to my mind is:
- The column IN and OUT are: In from the F5 to the Server and OUT from the Server to the F5, or is it the other way around?
- Why the Active one has got traffic on the OUT Column, if potentially is on Standby mode and therefore not sending/receiving traffic?
Thanks.
Hi,
IN is for Peer to F5 and OUT stand for F5 to the peer. I think that the OUT should include the monitoring traffic. You have traffic initiated from peer to F5 on the active unit only.

a_basharat_2591OK thanks, understood, So IN/OUT shoul be looked from the F5 perspective: In [traffic comming to the F5], OUT [traffic leaving the F5]. What still baffle me is the fact that the Standby is registering traffic toward the Servers. And they are the same statistics as on the Active Peer.
