NetXMS Support Forum

We are using some DSL based appliances that run on compact flash. I managed to get the agents nxagent installed ok  but when I query any agent param it reports that it does not support this parameter.  I can access the device from the server and it says it is active and I can view the agent config via the console.   However the client information shows Agent active but no agent version info.   I have run with the -D flag it shows the server accessing the agent but no other info.    I compiled th agent on a slackware box same kernel and GLIBC version and it works ok.    DSL is pretty cut down version of linux could there be a component missing?   

Thanks

Hello!

Try to do forced configuration poll on problematic node (right click node, select Poll -> Configuration). If it will not help, post configuration poll's output.

Best regards,
Victor

If I now right click and go tools, info Arp Cache (agent) I get "Error getting data from node: Parameter is not supported by agent."

I get the same message if I go tools, info , agent, Supported parameters.

Thank you for your help.

Some further info I confirmed  that libnsm_linux.so was available and had all its required libs.

ldd libnsm_linux.so
        libpthread.so.0 => /lib/libpthread.so.0 (0x4001f000)
        libexpat.so.0 => /usr/lib/./libexpat.so.0 (0x4006f000)

note I manually added the linux subagent incase that was the issue.

Notice the Requesting Parameter is empty ?

Try to build agent with configure option --disable-iconv. By default NetXMS uses iconv for character conversion, but it may be broken on your DSL router. Empty requested parameters most likely means that agent was unable to correctly convert UNICODE string received from server to single-byte string.

Victor you are a champion!  Thanks very much.
