create logs for LTM

Dears,

 

 

i need to create an iRule for generating logs for LTM including Client IPs, TCP port and the requested IP "vip IP"

 

 

i had a one but i don't know if is it right or not.

 

 

when CLIENT_ACCEPTED {

 

log local0. "[IP::client_addr]:[TCP::client_port]: New connection from client to VIP. Requested IP:port: [IP::local_addr]:[TCP::local_port]"

 

}

 

 

also i need to know how could i enable it for logging

 

 

Thanks in advance

 

 

Best Regards

    Hi Eslam,

     

     

    Your rule should work find to log the VIP IP:port on each new connection. Nitass gave a few more examples for different iRule log options. I'd recommend using High Speed Logging to send the logs to a remote syslog pool instead of logging each connection to the local disk. Doing the latter will eat up a lot of CPU cycles and disk I/O.
