NimbostratusHi
I need to write a irule that will tell me which backend node the traffic is being sent to. i have a irule that tells me which pool the traffic is going to and which URL it's calling.
when HTTP_REQUEST {
log local0. "[IP::client_addr]:[TCP::client_port] -> [clientside {IP::local_addr}]:[clientside {TCP::local_port}] -> [IP::remote_addr]:[TCP::remote_port] | pool: [LB::server pool] | URI: [HTTP::uri]"
}

hope this helps.
If you are using cookie persistence you could always decode the cookie hash..
Google around for decode bigip cookie or read below Actual python script:
!/usr/bin/env python
example string: 110536896.20480.0000
import struct
import sys
if len(sys.argv) != 2:
print "Usage: %s encoded_string" % sys.argv[0]
exit(1)
encoded_string = sys.argv[1]
print "\n[*] String to decode: %s\n" % encoded_string
(host, port, end) = encoded_string.split('.')
(a, b, c, d) = [ord(i) for i in struct.pack("
Running the script:
root@bt:~/bigip python bigip.py 110536896.20480.0000
[*] String to decode: 110536896.20480.0000
[*]Decoded IP: 192.168.150.6.
root@bt:~/bigip
I've passed this script down to developers and they love it.
