I see a spike in network activity but would like to see the top talkers for a given timeperiod. How can I view that info? I am using i2800 on 15.1.2.

 

Thanks.

Since you ask for the past, I think its doable with 2 options (from what I know), either with logging using an Irule or using the Analytics (AVR) module.

 

As you also called netstat, which is a real time data, not of past, I'll share few commands which I use, You can try these options,

 

Current Connections for a given VIP:

tmsh show sys connection cs-server-addr <VIP> | head -n -1 | tail -n +2 | awk '{print $1}'

You can add more filters like awk, cut, sort, uniq to find top source ip's consuming your respective vip.

 

Total Connections Count so far:

tmsh show ltm virtual <Virtual-name> | grep -E "Ltm::Virtual Server|Total Connections" | awk 'NR%2{printf "%s ",$0;next;}1' | awk '{print $3","$6}'

Live Connections Count on the box:

tmsh show ltm virtual all | grep -E "Ltm::Virtual Server|Current Connections" | awk 'NR%2{printf "%s ",$0;next;}1' | awk '{print $3","$6}'

Also you can use bigtop command,

bigtop -conn -once

Hope this helps.

When you say a given period, do you mean in the past or current traffic pattern. If current, you can use tmsh or bigtop commands. ​

 I meant sometime in the past. Also, is there any way on F5 to view client session info like netstat -ap etc?

Do you know how I can get a list of client IP addresses to a virtual server?
