you can use nxget command line tool to get any list or table. For example, to get interface list:

C:\Source\NetXMS\release>nxget -e0 -l 10.5.0.162 Net.InterfaceList
1 127.0.0.1/8 24 000000000000 lo0
2 10.5.0.162/24 6 000000000000 bge0

to get file system table:

C:\Source\NetXMS\release>nxget -e0 -T 10.5.0.253 FileSystem.Volumes
MOUNTPOINT       |VOLUME           |LABEL            |FSTYPE           |SIZE.TOTAL       |SIZE.FREE        |SIZE.FREE.PCT    |SIZE.AVAIL    |SIZE.AVAIL.PCT   |SIZE.USED        |SIZE.USED.PCT    |
C:\              |\\?\Volume{39e06104-63ef-11dd-92a4-806d6172696f}\ |                 |NTFS             |40015953920      |33852870656      |84.598435        |33852870656      |84.598435        |6163083264       |15.401565        |
D:\              |\\?\Volume{2ae1c26a-6dc5-11dd-8464-806d6172696f}\ |                 |                 |0                |0
        |0                |0                |0                |0                |0                |
A:\              |\\?\Volume{2ae1c26b-6dc5-11dd-8464-9be8208dfb96}\ |                 |                 |0                |0
        |0                |0                |0                |0                |0                |

There are two useful lists: Agent.SupportedLists and Agent.SupportedTables to get list of all lists and tables supported by agent.
