Additional Poller for APM

rajivbahl

HI

I have 2 NPM Pollers one is my main application which is behind the server Firewall and the additional poller is in DMZ for polling my Public devices. Now i need to add APM in my DMZ. Since i can't do it as APM is installed only where the NPM main poller is installed so no i am planning to install an additional poller also of APM in my DMZ server.

How can i configure and ensure that the monitors i am using for the devices is using my Additional poller of APM( the one in DMZ) to poll the application.

What i need to poll 
Example

 User Experience of Public DNS server, to probe  my Public DNS and check if is working which is on Internet.

Take at look at this link that explains (with diagrams!) how APM works w/r/t pollers.

Understanding How Pollers Work

Before you install an additional Application Performance Monitor (Orion APM) poller, review the following diagrams and ensure you understand how Application Performance Monitor polls when first installed and how Orion APM additional pollers work.

Orion NPM Additional Pollers are Poller-Aware

When you install an additional Orion NPM poller, the pollers are automatically aware. Poller-aware means each poller, including the Orion NPM server, polls only those nodes associated with it

Application Performance Monitor is Poller‑Unaware

When you add Application Performance Monitor (Orion APM) to your Orion NPM server, APM is poller‑unaware and can poll any node

Application Performance Monitor Pollers Made Poller‑Aware

After you add an Application Performance Monitor (Orion APM) additional poller and change the polling engine mode on your Orion NPM server, the Orion APM additional poller becomes poller‑aware, mimicking the behavior of Orion NPM. If you do not have an Orion APM additional poller on an Orion NPM additional poller, the nodes polled by that poller are not polled by Orion APM. For more information about changing the polling engine mode on your Orion NPM server, see “Installing an Additional Poller”.
