I am currently using NetXMS for monitoring space on the servers I use. I was wondering if its possible to change the Free/Used Sapce to show the value in GB rather than a percentage?
FileSystem.FreePerc({instance})
FileSystem.UsedPerc({instance})

I noticed in instance discovery it has this (no idea what it does or if its useful)
type = AgentReadParameter($node, "FileSystem.Type(" . $1 . ")");
if ((type == null) || (type == "") || (type == "CDFS"))
  return false;
return true;

Thanks!
