How to get all Pools for a Node

Hi,

 

I am trying to display all the pools for a node.

 

I have set "use iControlTypeCast", but still I have problems displaying the get_member method;

 

Has any body an idea?

 

 

thanks in advance

 

 

Ian

 

 

 

 

sub execute

 

{

 

my $sHost = shift @_;

 

my $sPort = shift @_;

 

my $sUID = shift @_;

 

my $sPWD = shift @_;

 

my $sNode = shift @_;

 

my $sProtocol = "https";

 

 

if ( ("80" eq $sPort) or ("8080" eq $sPort) )

 

{

 

$sProtocol = "http";

 

}

 

 

my $NodeAddress = SOAP::Lite

 

-> uri('urn:iControl:LocalLB/NodeAddress')

 

-> proxy("$sProtocol://$sHost:$sPort/iControl/iControlPortal.cgi");

 

eval { $NodeAddress->transport->http_request->header

 

(

 

'Authorization' =>

 

'Basic ' . MIME::Base64::encode("$sUID:$sPWD", '')

 

); };

 

 

my $PoolList = SOAP::Lite

  • The Pool::get_member() method returns a 2D array which is likely what is causing you an issue. You pass in an array of pools, and it returns a 2-d array with the first dimension relating to each input pool and the 2nd dimension with the members in that pool. I've streamlined your code a bit to make use of bulk calls. By calling the get methods only once you can reduce the round-trip time dramatically. Here's some code that will query all the node addresses and print out the pools that they belong to.

     

     

    * I've commented out the get_screen_names method becuase on my dev build of BIG-IP it was giving me some troubles. Uncomment for a production build and you should be fine.

    I ran this script and noticed that the section where you look for matches is not correct.

     

    In the node_list loop you use the same index for the pool_list.

     

    There should be another nested loop going through the pools and comparing each member.

     

     

    find some matches

     

    for $i (0 .. $node_list)

     

    {

     

    printf "----------------------------\n";

     

    printf "NODE : %s\n", $node_address;

     

    printf "Name : %s\n", $screen_name;

     

    printf "Pools : ";

     

     

    for $j (0 .. $pool_list)

     

    {

     

    $node_address = $node_list[$i];

     

    $pool_name = $pool_list[$j];

     

    @member_lists = @{$member_listsAofA[$j]};

     

     

    for $k (0 .. $member_lists)

     

    {

     

    $member = @member_lists[$k];

     

    $address = $member->{"address"};

     

    $port = $member->{"port"};

     

     

    if ( $node_address eq $address )

     

    {

     

    Found match!

     

    printf "%s, ", $pool_name;

     

    }

     

    }

     

    }

     

    printf "\n";
