irule logging / verification

Hello,

 

 

Is there a way to log what the forwarding request is for an irule? Basically looking to verify that the forwarding information is correct. I have tried using tcpdump but I'm not seeing anything at this point and the connection times out for the client.

 

Thanks in advance.

  • The issue we are trying to resolve is forwarding a request to another VIP on the same ltm. It's not a client redirect but rather a node selection using a vip address on the same ltm. We're doing this because the client is a service call and cannot handle a client redirect.

     

     

    Looks like the ltm arps for the address continuously and never sends the request on, even though it's on the same ltm.
  • you mean one virtual server calls another one on the bigip, doesn't it? can you post the configuration here?

     

    tmsh list ltm virtual (name)

     

    tmsh list ltm pool (name)

     

    tmsh list ltm rule (name)

     

     

    what is traffic? it is not http, is it?

    It sounds like the LTM issues a 30x redirect. Is that correct?

     

    If that is correct, what is the condition that causes the LTM to send a redirect? Does the service have (a) static IP-address(es)? If so, you could exclude them from the redirect. You mentioned that the service doesn't follow the redirect. Can you configure the service to connect to the correct VIP? Otherwise you might be able to create an iRule to select a different pool.

     

    As Nitass mentioned, it's a bit difficult to answer your question without more information.
