1) We've only installed NPM on the remote poller thus far. Do I also need to install NCM on this remote poller?
You must install the NCM additional poller (AP) package on the Orion additional poller server. The bits are located in the same download as the Orion additional package with NPM.
2) Can you assign nodes to specific remote pollers for configuration backup? If so where do you do this?
Once you have installed the NCM additional poller component on the Orion AP sever you must enable NCM additional poller support otherwise NCM will continue to do all its operations from the main NCM server. You will find the setting within the NCM settings in the web console. In fact after installing the NCM AP component you should see a warning banner in the web console informing you that you must enable the AP and a link to the settings page.
Once this is done NCM will perform its operations from which ever poller you have assigned to the Node in the Orion Node management.
The main thing to note is the difference between NCM 7.1 and NCM 7.2. If using NCM 7.1 you will have to login locally to each AP server and replicate your jobs within the NCM windows console application. The jobs will only operate on nodes assigned to that poller you can replicate the jobs exactly on each machine. Any actions performed from website will automatically be executed from the correct AP but jobs still had to be setup.
Now in the newly released NCM 7.2 jobs no longer have to be replicated on each AP as NCM is no longer using the windows task scheduler but taking advantage of the Orion job engine and will automatically schedule jobs to execute on the correct Orion Server. Jobs are also configured via the web console as of 7.2.
Hope this helps!
