Hi all

 

I have a requirement to log http 500 errors from 2 web servers behind a virtual server ip. I need to log the client ip that requested and also the server that give the http 500 error, I have the below but its throwing up errors in the logs, can anyone help cheers

 

when HTTP_REQUEST { set hostvar [HTTP::host] set urivar [HTTP::uri] set ipvar [IP::client_addr] }

 

when HTTP_RESPONSE { if { [HTTP::status] eq 500 } { log local0. “$ipvar requested $hostvar $urivar and received a 500 from [IP::server_addr]” }}

 

The error logs are

    can you double check the irule again? the one you posted looks correct.

    when HTTP_REQUEST { 
  set hostvar [HTTP::host] 
  set urivar [HTTP::uri] 
  set ipvar [IP::client_addr] 
}
when HTTP_RESPONSE { 
  if { [HTTP::status] eq 500 } { 
    log local0. "$ipvar requested $hostvar $urivar and received a 500 from [IP::server_addr]"
  }
}

    This is copied and pasted from my F5

     

    when HTTP_REQUEST {

     

    set hostvar [HTTP::host]

     

    set urivar [HTTP::uri]

     

    set ipvar [IP::client_addr] }

     

    when HTTP_RESPONSE {

     

    if { [HTTP::status] eq 500 } {

     

    log local0. “$ipvar requested $hostvar $urivar and received a 500 from [IP::remote_addr]” }}

     

    I am not seeing the node IP etc, and also what is the invalid command name that it keeps coming up with ?

     

    cheers

    It could be the quotes coming up as an upside down quotes when I copy and paste from certain editors (like e-mail and MS word) the quotes sometimes get changed to fancy quotes to open and close a quote.
