Can I only configure netxms using the NetXMS console? Is there any other config option? I've follow the step-by-step installation and at the end it says to use management console.
Currenty no.
Web interface is under heavy development, but in latest release (0.2.17) it's still read-only.
To configure system, your need to install "nxcon" from "netxms for windows" package.
Currently it is windows-only, but it works fine (and fast) under Wine (i have tested it with version 0.9.33 shippet with Ubuntu linux)
There are also a few requests for command-line configuration tool, but we need more user input on this to make some sort of vision before we start coding.
