is this usable?

 

 

Formatted Logging For W3c

 

https://devcentral.f5.com/wiki/irules.FormattedLoggingForW3c.ashx

Tks nitass, I will go to reivew.

 

 

One more question, how to check the object if I enable optimized-caching? And it will be logging if object caching?

 

 

Tks!

how to check the object if I enable optimized-caching?is this what you are asking?

 

 

sol13255: Displaying and deleting RAM Cache entries from the command line (11.x)

 

http://support.f5.com/kb/en-us/solutions/public/13000/200/sol13255.html

 

 

And it will be logging if object caching? HTTP_RESPONSE is not triggered when object is retrieved from cache. HTTP_RESPONSE_RELEASE is triggered. however, some HTTP:: command is not available such as HTTP::status.

 

 

HTTP_RESPONSE_RELEASE Wiki

 

https://devcentral.f5.com/wiki/iRules.HTTP-RESPONSE-RELEASE.ashx

Tks nitass, Displaying and deleting RAM Cache is useful for me.

 

 

On HTTP_RESPONSE_RELEASE , it cannot be trigger HTTP action like get or HTTP return code ... etc?

On HTTP_RESPONSE_RELEASE , it cannot be trigger HTTP action like get or HTTP return code ... etc?http method (e.g. GET) is saved since HTTP_REQUEST event. HTTP::status command is not valid in HTTP_RESPONSE_RELEASE event.

 

 

HTTP::status Wiki

 

https://devcentral.f5.com/wiki/irules.http__status.ashx

 

 

anyway, to have status code in log, you may use 2 virtual servers and call 2nd virtual server from the 1st one.

 

 

e.g.

 

 

 frontend virtual server (using virtual command and log)

root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list ltm virtual bar-frontend
ltm virtual bar-frontend {
    destination 172.28.20.14:80
    ip-protocol tcp
    mask 255.255.255.255
    profiles {
        http { }
        tcp { }
    }
    rules {
        myrule-frontend
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    vlans-disabled
}
root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list ltm rule myrule-frontend
ltm rule myrule-frontend {
    when HTTP_REQUEST {
   
    Save Request Side Information
   
   set http_request "\"[HTTP::method] [HTTP::uri] HTTP/[HTTP::version]\""
   set http_request_time [clock clicks -milliseconds]
   set http_user_agent "\"[HTTP::header User-Agent]]\""
   set http_host [HTTP::host]
   set http_username [HTTP::username]
   set client_ip [IP::remote_addr]
   set client_port [TCP::remote_port]
   set http_request_uri [HTTP::uri]
   set referer [HTTP::header value referer]
   virtual bar-backend
   log local0. "--"
}
when HTTP_RESPONSE {
   set response_time [expr [clock clicks -milliseconds] - $http_request_time]
   set virtual [virtual]
   set content_length 0
   if { [HTTP::header exists "Content-Length"] } {
      set content_length [HTTP::header "Content-Length"]
   }
   set lb_server "[LB::server addr]:[LB::server port]"
   if { [string compare "$lb_server" ""] == 0 } {
      set lb_server ""
   }
   set status_code [HTTP::status]
   set content_type [HTTP::header "Content-type"]
   set log_msg ""
   append log_msg "virtual=$virtual "
   append log_msg "client_ip=$client_ip "
   append log_msg "client_port=$client_port "
   append log_msg "lb_server=$lb_server "
   append log_msg "host=$http_host "
   append log_msg "username=$http_username "
   append log_msg "$http_request_uri "
   append log_msg "request=$http_request "
   append log_msg "server_status=$status_code "
   append log_msg "content_type=$content_type "
   append log_msg "content_length=$content_length "
   append log_msg "resp_time=$response_time "
   append log_msg "user_agent=$http_user_agent "
   append log_msg "referer=$referer"
   log  local0. $log_msg
   log local0. "--"
   log local0. $log_msg
}
}

 backend virtual server (using optimized-caching profile)

root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list ltm virtual bar-backend
ltm virtual bar-backend {
    destination 1.1.1.1:80
    ip-protocol tcp
    mask 255.255.255.255
    pool foo
    profiles {
        http { }
         { }
        tcp { }
    }
    rules {
        myrule-backend
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    vlans-disabled
}
root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list ltm rule myrule-backend
ltm rule myrule-backend {
    when HTTP_REQUEST {
        log local0. "--"
}
when HTTP_RESPONSE {
        log local0. "--"
}
}

 1st request (object is not cached yet)

 2nd request
 you can see HTTP_RESPONSE in myrule-backend is not executed because object is retrieved from cache

[root@ve11a:Active:Changes Pending] config  tail -f /var/log/ltm
