Node Connections

I am trying to develope a web interface to display the tcp connections to each of the nodes in a pool.

 

 

I have load balanced internal applications. Knowing which client servers are attached to a particular node in a pool is very valuable information for us to have.

 

 

Right now I ssh to the load balancers and run a command like this:

 

 

b conn | grep . It shows client servers connecting to the pool IP, then connecting to a node.

 

 

Using Powershell to do this and parse this info to a web interface is my ultimate goal.

 

 

Any help is much appreciated.

  • In v9.0 we removed the Connections interface due to it's very very large amount of data it needed to handle. This caused problems with the server generation of the XML SOAP Response. Thinks about it, in situations where you have 1000's or even 100's of 1000's of concurrent connections, trying to request them via a SOAP interface is not the correct way to go. At one point we were working on a paging mechanism but I don't believe anything came of it. If you really need this feature, then I'd suggest you go through Product Support and make a formal enhancement request.

  • OK, so i guess that answered my question on what data (get-f5.icontrol).LocalLBPoolMember.get_statistics provided. I am fairly new to powershell and I was trying to understand what the "CommonIPPortDefinition [][] members" parameter was about. So i was stuck. Apparently it won't provide the data I need anyway if you're saying this feature no longer exists in 9.0.
  • That method will return aggregate statistics for the given pool members across all client connections. For that method, you pass in a 1-D list of pool names, and a 2-D list of pool members (first index for the pool in parameter one, the second dimension for the members of that given pool).
  • Hey man,

     

    Did you ever get the web interface up and going? If so, mind shareing the code?

     

    Thanks,
