I now have a need to monitor a family member's PC that is located many kilometres from me. It fails randomly and I wish to capture (push) performance data over time to see if I can gain some clues as to what is happening. I thought of using NetXMS to assist!
I presume I need to do the following steps (I am assuming remote monitoring to NetXMS is "technically" possible over the Internet...):

1. Install Agent on remote PC
2. Ensure remote PC firewall has port 4700 open
3. Set up another user account on my NetXMS server (how do you do this?)
4. Define DCI's that capture the data I want
5. Set up "push" mode data collection
6. Enable encryption on both Agent and Server
7. Set up the NetXMS server with a DNS name (using Dynamic DNS?)
8. Type NetXMS DNS name into Agent field (where i normally type the IP Address)

Have I summarised the steps correctly? What have I missed?  What are the risks? As you can probably guess I don't have a detailed understanding of the Internet (very basic) so any feedback appreciated. Chris
