Report for down nodes

Hi Dean,

 

 

Probably your best bet is to write an iControl script. iControl is a SOAP API for making requests to a BIG-IP. We offer libraries for a number of common script languages (Perl, Python, Ruby, Powershell, etc.), so there is more than likely one that will meet your needs. Here are a few resources to get you started:

 

 

iControl Wiki (http://devcentral.f5.com/wiki/iControl.HomePage.ashx) - lots of code samples from numerous scripting languages

 

iControl API Reference (http://devcentral.f5.com/wiki/iControl.APIReference.ashx)

 

iControl LocalLB::Pool interface (http://devcentral.f5.com/wiki/iControl.LocalLB__Pool.ashx) - this is where the majority of the methods you'll need for querying pools will be

 

iControl Management::Partition interface (http://devcentral.f5.com/wiki/iControl.Management__Partition.ashx) - where the active partition to query is set (note: partitions have been deprecated in favor of folders in version 11)

 

 

I am more Ruby-centric, so I whipped up a small script that will report pools without active members. I hope this gives you some fuel to get started. Feel free to reply with any further questions.

 

 

!/usr/bin/ruby

require 'rubygems'
require 'f5-icontrol'

def usage
  puts $0 + '   '
  exit
end

usage if $*.size < 3

 set up Management::Partition and LocalLB::Pool interfaces

bigip = F5::IControl.new($*[0], $*[1], $*[2], \
['Management.Partition', 'LocalLB.Pool']).get_interfaces

 grab a list of partition and loop through them

partitions = bigip['Management.Partition'].get_partition_list

partitions.each do |partition|

   set the active partition to query

  partitions = bigip['Management.Partition'].set_active_partition(partition['partition_name'])

  puts ('' * 5) + " {partition['partition_name']} " + ('' *5)
  puts

   grab a list of pools and stuff the array into a variable

  pools = bigip['LocalLB.Pool'].get_list.sort

  pool_active_members = bigip['LocalLB.Pool'].get_active_member_count(pools)

  [ pools, pool_active_members ].transpose.each do |pool|
    puts "{pool[0]} - {pool[1]} available members"
  end

  puts
end
