BIGPIPE

Hi there,

 

 

Does anyone know of any useful bigpipe commands I can use to troubleshoot if traffic is making it to the virtual server, pool and member servers?

 

 

We had a situation the other night where we were having some issues load balancing traffic to a virtual server and the only traffic information I could rely on was the traffic statistics on the GUI.

 

 

I really would like to know for fact weather traffic is making it all the way to the pool member. I would also like to display persistence statistics.

 

 

I did read the BIG-IP® Command Line Interface Guide but could not find what I am looking for there.

 

 

Thanks,

 

 

-Ryan

    The tool to see traffic is tcpdump. It's basically a command line sniffer that is on the LTM.

     

     

    The following is a link to the TCPDUMP information on the ask.f5.com support site (Click here)

     

     

     

    As for seeing a persist stats you should be able to within the GUI statistics and select persistence records.

     

    If you are looking for the actual records then go into the CLI and use the following command

     

    bigpipe persist help

     

    This will output the commands you might need to spell out all the persistence record for the specific virtual server.

     

     

     

    Hope this helps,

    tcpdump is definitely the most complete troubleshooting tool. If you want to quickly check connection stats you can use 'b virtual VIP_NAME' to get a dump of the stats for the VIP and its resources (iRules, pools, etc).

    Be sure to also read SOL6546 which is linked from the original article that CB linked to. If your virtual server is PVA accelerated you may not see all of the traffic in tcpdump.
