performance - F5 bigip load balancer real time monitoring of requests / responses timing -

-

i'm looking way monitor requests / responses timing in real time. how many requests processing right now, , how long each request being processed ( when started, pool / server ) there way push / pull information f5 when request start processing , finished processing to/by external tool show information in real time ?

are there tools allowing f5 load balancers or other http load balancers ?

tia.

if understand question properly, think should looking either tcpdump or use cs-command generates tabular output , gives information on following:

when using tcpdump in case, may want include option output written file. recommend because can examine file ethereal bit more user friendly , enables filter on lot more things might in search of. syntax follows:

using tcpdump

tcpdump -vvni 0.0:nnn -s0 host 1.1.1.1 or host 2.2.2.2 or host 3.3.3.3 -w /var/tmp/filename.pcap      or  tcpdump -nvvv -i -c 20 '((port 80 or port 443) , (host 10.0.3.169 or host 10.0.3.1)) , dst host 10.0.3.246' > filename

the tcpdump should used cautiously, uses system processor cycles if not used well.

note: ( -c 20) above in command output 20 lines of result, without switch, endless stretch of output obtained. use of cut down on cycles used, can repeated several times accumulate volume of information obtained. unless not problem on network used.

using cs-server command:

the below commands can use perspective of client side , server side different options available, further below, took liberty include explanations of possible combinations of these commands (obtained f5 site). also, output of command broken 5 parts, below explanation of output translates to.

tmsh show sys connection cs-server-addr

tmsh show sys connection ss-server-addr 

  (1)         (2)         (3)           (4)               (5)

x.x.x.x:64231 x.x.x.x:443 x.x.x.x:64231 x.x.x.x:443 tcp 21 (tmm: 7) none y.y.y.y:49632 y.y.y.y:443 y.y.y.y:49632 y.y.y.y:443 tcp 16 (tmm: 0) none

the client ip address , port (1) virtual server ip address , port (2) selfip (snat) address , port (3) ip address , port of member server request went (4) tmm process processing connection (5)

cs-client-addr specifies clientside remote address of active connections cs-client-port specifies clientside remote port of active connections cs-server-addr specifies clientside local address of active connections cs-server-port specifies clientside local port of active connections protocol specifies protocol used specified connections (for example: tcp, udp) ss-client-addr specifies serverside local address of active connections ss-client-port specifies serverside local port of active connections ss-server-addr specifies serverside remote address of active connections ss-server-port specifies serverside remote port of active connections
