Load Balance Microsoft Workflow 1.0 Servers for Sharepoint 2013

Hi Mike,

Yes the communication between workflow and SP is not totally blocked. It says on the Workflow Logs that the F5 VIP failed to response when establishing connection.

Yes it is using FQDN and on the Work flow we use https:(fqdn)or(IP)/etc of the VS but still on the Workflow Manager logs says Could not connect or failed to establish connection to f5 VIP.

Okay, I would first look at the BIG-IP connection statistics for the VIP. Do you see connections to the SP VIP and pool members when workflow attempts to connect?

If you do, you can add an iRule like this one to the SP VIP to log the requests and responses to verify you are seeing requests from the workflow servers:

when HTTP_REQUEST {
    log local0. "Request:[HTTP::host][HTTP::uri]:[HTTP::header names]"
    foreach cookie [HTTP::cookie names] {
      log local0. "Cookie name: $cookie, Cookie value: [HTTP::cookie value $cookie]"
   }
    foreach aHeader [HTTP::header names] {
      log local0. "$aHeader: [HTTP::header value $aHeader]"
   }
}
when HTTP_RESPONSE {
    log local0. "Response: [HTTP::status]:[HTTP::header names]"
    foreach cookie [HTTP::cookie names] {
      log local0. "Cookie name: $cookie, Cookie value: [HTTP::cookie value $cookie]"
   }
    foreach aHeader [HTTP::header names] {
      log local0. "$aHeader: [HTTP::header value $aHeader]"
   }
}

Hi Mike,

Thanks for the script. I will try this and will get back here.

Mike, as per testing on the iRule I don't see any logs.

You are looking at /var/log/ltm, correct?

Yes Correct.

Not sure what's going on, but first we need to determine why the traffic isn't making it to the virtual server.

It is strange because on the http watch we saw a traffic to f5. But when we setup the iRule no logs hitting.

Hi Mike,

It's been a while. Do you have any lead on this? I already open a TAC case for this, just now.
