Detail
All of us know SolarWinds SLX license you can montior up to 12000 Elements and beyond this you will need an Additional Polling Engine to monitor.
What is Stackable Poller idea
Stackable poller means license extension on polling server if your server hardware can handle it , with the latest version of SolarWinds NPM, you can now install up to three unique polling engines on a single polling server, sharing a single IP address. Stackable polling engines enable you to effectively triple the polling capacity of a single server so you can get benifit of available server hardware within the existing installed enviornment
Further it will help you to monitor more Elements ( Nodes/Volumes/Interfaces/Services ) without having any dedecated servers to be confirmed and manage so its less overhead for the I.T staff to manage .

How many Stackable Poller license I can have on the Single Server?
Up to three total polling engines may be installed on a single server (i.e. one primary NPM
polling engine with one or two additional polling engines on Primary Server or three additional polling engines on
the Additional polling server ).
Note: A stack requires only 1 IP address, regardless of the number of APEs
Can I install Stackable Poller on my existing Additional Polling Engine?
Yes 'Stackable Poller' is basically only extending the licensing capability on the Poller you can have multiple Stackable poller on your existing Additional Poller It can be update by Smart Bundler .
How can I update my Poller for Stackable Poller?
On the Poller it can be updated by Smart Bundler.
It means that by additional poller package downloadable from customer portal (not the Individual Downloads, but the Main Additional Poller Installer also called Smart Bundler).
How to install Stackable Poller on my Primary Polling Engine?
In this example I am assuming we are implementing Stackable Poller on the Main Poller (that has enough resources to tackle additional load)
As you are aware a single poller can tackle upto 12k elements
Also there is no special installer for Stackable Poller
You will need a license to be purchased as for Additional Polling Engine
You will go into your Customer Portal & download the Additional Poller Smart Bundler (not the Individual Downloads, but the Main Additional Poller Installer also called Smart Bundler)
Basically when you will run Additional Poller Smart Bundler this installer will say on the main poller that everything is already installed and ask you if you want extend license.
Now simply key in the license of the Additional Poller in the wizard
It will never install anything on main poller it only just update the license
So the customer has got extra capability to fully utilize his server
Also after the license has been applied you can open the License Manager and you will see another entry in the Lincense Manager as following
On Primary Polling Engine it will take up to 2 MAX Additional Polling Engine license keys
On Additional Polling Engine it will looks like this
You will have the message "The machine has reached to license limit" after that therefor it will only be able to take up to 3 licenses.
So if I have have mutiple modules installed on the Primary Poller (do I have to install all the other modules as well , because Smart bundler will download say APE SAM , APE UDT , APE NPM)
so when I run the Smart Bundler on the Primary poller (it will not say that Primary Poller is already installed on this machine)
Yes, it will say on main that everything is installed and ask you if you want extend license
so it will never install anything on main, just update license
If I will install Stackable Poller on my primary server it will increase the capacity to 24K elements to tackle?
It will ask you on main to add license key for additional poller (means 24k elements). Once you run it again, you can add another AP license (means 36k elements) and if you run it third time,
it will say This machine has reached its license limit . The same functionality is for Additional Poller installation And yes, Stackable poller means license extension on polling server
