LocalLB.PoolMember

I'm a newbie to F5.i am trying to associate a monitor with a PoolMember with the snippet below. It doesn't throw any error, even checked by dumping the response

 

 

On verifying from GUI, the monitor is not associated for that poolMember

 

 

sub setmonitor {

 

my ($ip,$port,$pool,$lb);

 

my $soap = SOAP::Lite

 

->uri("urn:iControl:LocalLB/PoolMember")

 

->proxy("https://$lb/iControl/iControlPortal.cgi")|| die "Can't create SOAP object for $lb\n";

 

 

my $address_type ="ATYPE_UNSET";

 

my $ipport = { 'address' => $ip, 'port' => $port };

 

my $member ={ 'address_type'=>$address_type,'ipport'=>$ipport};

 

my $monitor_rule={'type' => 'MONITOR_RULE_TYPE_SINGLE', 'quorum' => 0, 'monitor_templates' => ['tcp']};

 

 

my $soapResponse = $soap->set_monitor_association(

 

SOAP::Data->name(pool_names=>[$pool]),

 

SOAP::Data->name(monitor_associations=> ['{member=>{$member}, {monitor_rule =>$monitor_rule}'] ) );

 

 

 

print "Response", Dumper($soapResponse), "\n";

 

if ( $soapResponse->fault ) {

 

print $soapResponse->faultcode;

 

print $soapResponse->faultstring;

 

print "ERROR";

 

}

 

}

 

 

 

Thanks in advance

    This is a common question with dynamic languages. The method for set_monitor_association is 

    set_monitor_association( 
     in String [] pool_names, 
     in LocalLB__PoolMember__MemberMonitorAssociation [] [] monitor_associations 
 );

    You are calling it with this: 

    set_monitor_association( 
     in String [] pool_names, 
     in LocalLB__PoolMember__MemberMonitorAssociation [] monitor_associations 
 );

    The second parameter for monitor_associations is a 2-d array so you can pass in multiple monitor_associations for each passed in pool member. You are passing in a 1-d array and the server is interpreting that as a 2-d array with the 2-nd dimension being size zero and thus a no-op is occuring. You'll want to make that monitor_associations a 2-d array. 

    ... 
 my $monitor_rule={'type' => 'MONITOR_RULE_TYPE_SINGLE', 'quorum' => 0, 'monitor_templates' => ['tcp']};  
 my $monitor_assoc={'member' => $member, 'monitor_rule' => $monitor_rule} 
 push monitor_assoc_array, $monitor_assoc; 
 push monitor_assoc_AofA, monitor_assoc_array; 
  
  
 my $soapResponse = $soap->set_monitor_association( 
   SOAP::Data->name(pool_names => [$pool]), 
   SOAP::Data->name(monitor_associations => [@monitor_assoc_AofA]) 
 );

    Disclaimer, I haven't tested this so hopefully it works for you. But, you get the idea, you need to make sure that the parameter is declared as an array and then coerced into a 2-d array with brackets. I'm sure there are other ways to do this, but this has worked for me in the past.

    Great!

     

     

    Debugging issues with the perl libraries can be tricky at times. Feel free to post again if anything else comes up.
