C# iControl WideIP to LTM Pool

We have GTM devices in several datacenters and when trying to find out where a website is active it sometimes takes a few clicks to get the data - and it isn't in one view. So I was trying to make a little web page to show GTM WIP --> GTM Pool --> Server Name / Datacenter --> LTM Virtual Server --> LTM Pool. Eventually I would like to have the ratio at the GTM level if I am split between datacenters instead of 100% traffic to one datacenter.

 

 

I have some working code, but I am sure there is a much more efficient way to do what I am trying to do, so I am just looking for a better way to get information for a specific Wide IP pool - specifically searching for just one instead of iterating through all of them and can I get back the "Server Name" and "Data Center" fields. Also the same applies at the pool level.

 

 

My output (pre-formatting) is like this:

 

Info: datacenter1-external-ltm1 datacenter1-internal-ltm1 gtm_pool gtm_datacenter ltm_pool_the_VS_points_To

 

 

Thanks

    That's going to take some time for me to dig through your code. Is it working for you and you are just looking for ways to optimize it?

    Joe,

     

     

    Correct. I want to optimize it and make it a little more flexible. This also seemed like a good example to learn about how to get data for just one WIP/VS/Pool.

     

     

    In the long run I want to be able to take my WideIP, show what Pool it goes to and show the ratio between DataCenters.

     

     

    What I am trying to improve I think is as follows:

     

     

    1) Put in the WIP and get the pool it points to (right now I know what pool is used for the WIP so I hard coded it to just look at the pool)

     

    2) Get the GTM/LTM pool directly instead of getting all pools and iterating through them to find just the one I want to look at

     

    3) Find out how to access the 'Server Name' and 'Data Center' values that I see in the GTM for the GTM Pool (this is on 10.2)

     

     

    So although a working example would be great I think I can put something together if I can just figure out which functions I should use for the above or if I can even get back the values easily.

     

     

    I am thinking eventually I would look for output something like this (assume I send it the WIP mytest.com)

     

     

    WIP: mytest.com

     

    --> GTM Pool: pool_mytest

     

    --->DataCenter1 - Ratio X

     

    -----> LTM Virtual Server: vip_web_mytest

     

    ---------> LTM Pool: ltm_pool_mytest

     

    --> DataCenter2 - Ratio Y

     

    ----> LTM Virtual Server: vip_web_mytest

     

    ---------> LTM Pool: ltm_pool_mytest

     

     

     

    I hope that makes more sense.

     

     

    Thanks

    For the first part I can get just the Wide IP Pool -

     

    string[] wip = new string[] { "www.mysite.com" };

     

    string[] wip_pool = new string[] { vs_wip[0][0].pool_name.toString() };

     

    iControl.globalLBPoolPoolMemberDefinition[][] pool_members = m_interfaces.GlobalLBPool.get_member(wip_pool);

     

    string p_addr = pool_members[0][0].member.address;

     

     

    However from this point I am still not sure how to get the additional information for the member - namely the member name, server name and data center values that are listed in the web GUI for the pool. I am thinking this is more of a calculated value than a property of the pool, but looking through the API guide I don't see any place that this is exposed. It looks like I would have to query every LTM to find the member.address.

     

     

    So I think that I have my first two goals covered but still not seeing in the API guide how to get the above data easily.

     

     

    Thanks
