That helped immensely! I didn't realize I couldn't just output the contents to a table or was doing it wrong so it only gave me a systemdatasource message a hundred times over.
I've got the first hurdle of my script working and even included some caption logic. Next is some SNMP string logic and I'll need to run this same type of ForEach-Object loop against the interfaces table. I'm looking for examples on this currently but I'm assuming it's the same format as the addNodes was and I can just change it to match the rows in the DB.
Once that is tackled I get to try and make a web form so that someone can add a single node or a CSV list of nodes to the system without touching the server. Fun fun!
Might have a better time using SOAP and 17778 for the single node and interface addition but I haven't even gotten started looking in that direction yet.
Thank you again! Would it be alright if I ping you with questions regarding the other areas I'm going to venture into next or should I post something here first? Wouldn't want to wear out my welcome.
